Offisite DB Connection Failure
Dec 18, 2006
I am trying to write a simple program for test purpose with VB .Net 2005 and SQL Server Express 2005. My server is not even in the same state as me, but I have the following on the server:
Server 2003 Web Edition SP1
SQL Server Express 2005
I am writing in the following:
Visual Basic 2005 Pro Edition
I have read where you can setup Express to allow TCP/IP connection, and I have done what it stated HERE (http://www.datamasker.com/SSE2005_NetworkCfg.htm). However, I am still not able to connect to the DB on the remote server.
I go to:
Tools --> Connect to Server --> Type IP and get the connection failed to connec to server "xxx.xxx.xxx.xxx"
I even tried:
Tools --> Connect to Server --> Type IPSQLEXPRESS and get the connection failed to connec to server "xxx.xxx.xxx.xxx"
Has anyone been able to do this, or am I wasting my time? If I can get the SQL Server to do as requested then I am going to purchase and work with it, however, I want to test out before I spend the $$$$$ to begin the full project. If anyone can be of assistance here I would appreciate it.
Thanks in advance.

Hi
My flatform is NT4 with Sql 7 server. At least one a week user loose connection to the database on the Sql server. I can ping the server ok but an error message pops up each time they try to access the database that the server is not known to be running. What performance monitor counter can I monitor to determine if there is a problem accessing the database.

hi all,
my problem is failure in the connection to SQLserver2000 remotly( to city a) by enterprise manager or query analyzer via windows authentication ( this error appears "login failed for (domain/user)" ),while no problems happened in the connection when i would to connect to other servers at other locations(to cities b,c) via windows authentication.
note that i can access to (city a)server via sql server authentication , but i want to access to this server(city a) via windows authenication as the other locations because this authentication mode is policy of our system, and note also that persons in city b can access to all servers (city a,c) via windows authenication .

Hi, I was using an accounting software which uses sql server 2005 express and while I was processing a transaction my machine got stuck and didn't allow to do any operation and I had to restart the machine.I've connected to a domain and after I logged in to the software I can process all other transactions but Couldn't process the one I tried when the machine got stuck. It says connection failure and Select * command dosent work. the software runs in the domain and it need .net frame work 2.o and Windows Installer 3.0 for installation.(Sage Pastel Evolution).I removed sage and Sql server completely and reinstalled but the result was same. Then I applied a patch for clearALLPool but I'm in the simmillar situation

Hello there!
This is my issue: I do have a database which back end is in SQL Server 2005 and front end is in ACCESS 2003. When one of the forms is trying to write duplicate information in any of the tables, there is a message coming "ODBC -- call failure", I wrote code trying to avoid that situation, but is keeps on coming. Does anybody have any idea about how to handle this exception? I would really appreciate a help on this subject.
Thanks;

My application (written in a proprietary old 4GL) is connecting to a SQL 2000 database via ODBC
This works fine nearly all the time, but occasionally, it throws the following error when trying to connect :
Connection Failed
SQLState '01000'
SQL Server Error: 10060
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]Connection Open(Connect()).
Connection Failed:
SQLState '08001'
SQL Server Error: 17
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]SQL Server does not exist or access denied.
This error is displayed in a Windows dialog box. When the OK button on this dialog is clicked, it throws up a login/password box. When this is filled in and submitted, the connection is usually made cleanly and the application continues.
The big problem is that the application is an unattended service, and this dialog can go unnoticed for quite a while.
If these dialogs are 'Cancelled' rather than 'OK'd, the 4GL receives the error and arranges to re-try the connection itself.
Is ODBC responsible for popping up the interactive dialog, and, if so, can I do anything to force it to return an error instead ?

I am having a problem getting the ODBC driver to connect.
I just installed VS2005 and can't connect to my SQL2000 server. It is there. I can't connect using either one of the mix mode authentication.
I can login to SQL from another pc when logged in with this user name. It has to be something on this pc blocking it.
Iam not rying to do this from a ASP web page just trying to setup a ODBC driver and I get these errors.
I get the error:" Login failed for user (null)" Not associated with a trusted connection
Thanks

Hi,I need some help. I am getting this error after I complete the asp.net register control and click on the continue button. It crashed when it tries to get it calls this Profile property((string)(this.GetPropertyValue("Address1")));When I look at the stack, it is coming from my ProfileWrapper class which adds user address, city, etc.. from a class which inherits fromSystem.Web.Profile.ProfileBase. From the stack, it is calling the System.Web.Profile and crashed when it tries to open a connection atSystem.Data.ProviderBase.DbConnectionPool.GetConnection(DbConnection owningObject). I already migrated all aspnet_user, aspnet_roles, etc.. and don't get any connection errors. It is only when I try to get the profile data. This works on my pc, but throws an error on my lunarpage website.Any help is greatly appreciated.Thanks,AJAn error has occurred while establishing a connection to the server.

Hi all,
I installed a MSDE on a Windows XP SP2 and configured it for accepting remote connections. But It shows the "SQL Server doesnot exist or connection denied" message whenever I try to connect to this server. For more information I am adding more facts
* It is an MSDE and not a WMSDE
* Firewall is turned off
* Server process is listening on 0.0.0.0:1433
* TCP/IP and Named Pipes are enabled using server network utility
* LoginMode=2 is set for mixed mode authentication in the registry
* Tried restaring the Process and even windows after the changes.
Please help me !!
Thanks in advance

Hi,
Yesterday, one of the computers on the network of our SQL server experienced a connection failure while using two specific jobs in a table containing assignments for jobs. The data interaction occurs from a Data Access Page, and from what I've learned, the nature of a DAP is such that the client not only connects to the web server but actually also establishes a direct connection to the SQL Server (we use a backend of MS SQL Server 2003). The data is still inside the tables, but on the Data Access Page, any data that was opened during the connection failure does not show up anymore from any computer.
My guess is that there was corruption of some sort on another layer beneath the actual data layer that cannot be accessed directly or viewed. To remedy this problem, I am going to try to recreate all affected records and rebuild all table ID ties manually with append and update queries. Does anyone know the actual problem or corruption that occurs during a connection failure? Is there a way to access the affected layer(s) and undo the corruption or remedy the affect so the records can be used? Is the problem with the SQL Data itself or on a layer with MS Access/MS DAP?
This data is very important and needs to be used today and was supposed to be used yesterday. If anyone could help me in this matter or provide a better way to undo the supposed corruption, it would be greatly appreciated :)!
thanks in advance,
mellamokb
PS - I don't know if this makes a difference, but other data has been changed in the same database/tables since the connection failure, so a complete reversion back to the system at that point in time would mean loss of other updated data.

Just stumbled over the interesting bug -
if you have an SQLExpress server and the "allow remote connection" in SQL Instance is turned ON, it doesn't means that it works if you create some aliases for this instance
If Im trying to connect to SQLExpress via new created alias ('localhost' for example) I got the "SQL Server does not allow remote connections" error. Albeit, connecting to ".SQLExpress" is successful.
I've checked the properties of locahost DB instance in SQL Management Studio - remote connection is allowed.
I've restarted the SQLExpress instance.
There is no SQLServer or other instances on my PC
But it doesn't work
How to fix this and allows to connect to sql instance via aliases?

I have some tables that I need to wipeout and reload once per day. So I have created a T-SQL task that does a truncate table, then a data flow task, then a update statistics task. Running those works fine, but as soon as I put them all into a sequence container and set the container to require transactions, the first step gets a connection failure. "Failed to acquire connection "<name>". Connection may not be configured correctly or you may not have the right permissions on this connection". I am using a .Net SQLClient data provider for the T-SQL task and in the data flow task I have to use a OLEDB provider so that I can run the task locally in development.
Is there something I am doing wrong or is there some other way to handle truncate, load, update stats all in a transaction?
Thanks.

Hello,
I have encountered a problem with my data source connection. I have a data souce that uses a SQL Login to access a remote server. When I test the connection in the Data Source Designer all works fine. Even when I add the data source as a new data connection in my SSIS package an use it in a OLE DB Source component it works fine, in the preview window.
But when I try to run the package in debug mode i get the following error message,
SSIS package "rXolapform.dtsx" starting.

Does anyone have any idea of what it could be?

Hey all, 2 questions.
Is there a way to 'refresh' the value of adodb.connection.state? and When my ado class reconnects after a dropped connection i still get connection failure errors.
I'm trying to make the connection b/n the my work's app and mssql server more 'robust'.
Our ado class tests the connection in the 'execute' method ie if connect() execute db task
.connect() is
IF this.loConnection.State = adStateOpen
*-- The connection is already open.
ELSE
create connection
ENDIF
return (this.loConnection.State = adStateOpen)
Now, this works fine when starting up the app, and everything runs fine, but *in theory* it should be able re-establish the connection at any time. So i kill the connection @ on the sql server while the app is running and try to perform a task that requires a db connection.
problem is that 'this.loConnection.State' is still equal to 1 even though the connection is no longer there.
It gets changed to 0 when the .execute fails but the failure is less than graceful... and although it reconnects (sp_who shows a new connection), it seems like the ado object is trying to connect using the old connection rather than the new one. command.activeconnection is set to the new connection in the .connect method so i dunno what's up.
Any ideas?

Overview. I am converting over from MSDE to SQL Express. My front end program is unable to connect to the database. To troubleshoot, from the remote computer I tried connecting with the management program and I get the Error 26 unable to connect.
(The connection string worked previously (yesterday) when using MSDE as the server. When I installed SQL Express I named it the same instance as the server name under MSDE. I also use server authtication on both with same user name and password. As stated below I cannot connect using the managment console.)
Here is what I have done: I made sure that the SQL Server configuration has been changed to allow network connections (both TCP and named pipes). I have disable windows firewall on both machines. I confirmed that I can connect from the remote machined to the server by network browsing. Both machines are running XP Proff. There is no other security software running on either machine.
More Info. when attempting to log on I am using the server authntication, I use "sa" as the user id plus my password.
Goal. The front end of database program connects to the server remotely using a program called Hamachi over the internet. This works without a problem on MSDE. But for now I am simply try to connect using the managment program which lets you browse for other serves. When I do this it shows the remote computer, but not the name of the computer but not the SQL server which I type in like the following: "INTELsql1"
What I have not Done: I have not changed any permissions or added any users to the server, since this does not seem necessary. As stated the user of remote machine can connect to the server and change files.
Would appreciate any suggestions or tips. Thanks.
I HAVE READ THE POST FROM MAY 13, 2007 AND TAKEN ALL STEPS SUGGESTED EXCEPT MAKING SURE THE BROWSERS SERVICE IS RUNNING ON SERVER WHICH I WILL DO NOW.

Hi,
I have very little, to zero, IT configuration knowledge and I am hoping that someone is able to help me out.
I am currently writing the SQL scripts and developing the reports in the SQL Server Business Intelligence Development Studio, and then deploying the reports to the server for managers to eventually view.
Recently the IT section updated the test database (temp) that is connected to SQL Server 2005, with the live database (production), so that the data and database structure were up to date for me to create the reports.
When the update was done, the connection to SQL Server failed, and the newly appointed IT person responsible for SQL does not know how to resolve the problem. Up until yesterday I was getting a message that said that the connection has failed and then today I have the following message (she has been trying very hard to get it working):
An error occurred during local report processing.
An error has occurred during report processing.
Query execution failed for dataset 'Division'.
The SELECT permission was denied on the object 'Dim1', database 'payglobal', schema 'dbo'.
The reports that were deployed to the server prior to the update are still accessible however I am unable to review any reports I edit within the Development Studio. It has been out of action now for nearly two weeks.
Could someone please give me very detailed instructions on where the IT person should look, and what she should do to fix the problem. I will then pass these onto her.
Thanks.

I'm having a big problem with a SQL 2K5 cluster (using standard edition). I can get onto the box and connect to the sql server locally fine. However when I try to connect remotely I get errors.
Let's call the two sides of the cluster, CL1 and CL2 and the "virtual server" is CL3. Locally I can connect without any problem at all to the SQL server, but I just can't connect to it from any remote machine.
The server in question is instance name LMS_PRD running on CL3, port 10051. TCP/IP is definitely enabled for local and remote connections (I have checked this in the SQL server surface area configuration). I can connect locally without any problem. Also, locally, if I do,
telnet CL3 10051
it connects fine
From a SQL 2000 box - when I try to connect from sql query analyzer, I get
"Unable to connect to server LMS_PRD Server Msg 17 ... SQL server does not exist or access denied"
Client network utility shows server alias - LMS_PRD, TCP/IP, CL3LMS_PRD,10051
[I can connect to other SQL 2005 servers OK from this same server using this same method]
On this box, when I do telnet CL3 10051 , I get "Connecting to CL3...Could not open a connection to host on port 10051 : Connect failed"
[When I do a similar one for another SQL 2005 box, "telnet U01 10051", it connects fine]
From another SQL 2005 box - when I try to register the server, I get
"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: TCP provider, error 0 - No connection could be made because thew target machine actively refused it.) (Microsoft SQL Server, Error: 10061)"
IN the SQL native client configuration it shows alias name - CL3LMS_PRD, server=CL3LMS_PRD, protocol tcp, parameters 10051
Again if I do telnet CL3 10051, I get the error above.
From this same box I can register another SQL 2005 server without any problem and do the telnet to it OK
Just to emphasise:
(a) The SQL server configuration manager shows that TCP/IP is enabled, and that 10051 is the port (in IPALL, TCP port). Also I have checked the SQL server errorlog - it is definitely using 10051 as the port.
(b) The SQL server surface area configuration shows under local and remote connections using both TCP/IP and named pipes selected (I've tried both this and the using tcp/ip only option)
(c) SQL server browser is running
(d) There are NO firewalls etc involved
Any help or advice MUCH appreciated
Any thoughts anyone?

I have a problem establishing multiple connections in Management Studio. It is hard to describe, but it happens consistently when I try to open a new connection.
I can connect to the database engine successfully but when I try to open a "new query" the application just goes away without any errors. Both of these features requires their own connection and currently I cannot open both of them together and constantly have to switch back and forth by closing the tool. There are no messages in the sql error log, event viewer or windows log.
I believe it may be a problem with the installation of Management Studio because I only get this problem through my remote connections. I don't encounter this error when I access the server through Management Studio from my workstation and open multiple connections.
Has anyone seen this or can someone offer me some direction as to where to look?

This has me totally baffled. I have a default instance of SQL Server 2005 on a server and I installed a second instance on the same server. It worked fine until I rebooted the server. Now I cannot connect to the second instance. The error message mentions remote connections but I'm not trying to connect to the instance remotely. The entire error message is below. Has anyone come across this?
===================================
Cannot connect to SERVERINSTANCENAME.

Hello,
I'm looping through a set of IP's (sql servers), i'm changing the property ServerName for OLE DB connection dynamically.
So, I'm having a DataFlow Task inside a For each Task.
Data Flow task has OLE DB Source & OLE DB Destination. I've set ServerName of OLE DB Source to a variable which gets updated by For Each Loop.
Till now everything is working fine. However, if a Server (IP) is down it causes OLEDB Source to give an error.
So in my case, if one server is down, it gives error and does not proceed further. I want it to continue with other
servers.
How do i error handle this ?
Thank You,
Sandeep.

I'm having a big problem with a SQL 2K5 cluster (using standard edition). I can get onto the box and connect to the sql server locally fine. However when I try to connect remotely I get errors.
Let's call the two sides of the cluster, CL1 and CL2 and the "virtual server" is CL3. Locally I can connect without any problem at all to the SQL server, but I just can't connect to it from any remote machine.
The server in question is instance name LMS_PRD running on CL3, port 10051. TCP/IP is definitely enabled for local and remote connections (I have checked this in the SQL server surface area configuration). I can connect locally without any problem. Also, locally, if I do,
telnet CL3 10051
it connects fine
From a SQL 2000 box - when I try to connect from sql query analyzer, I get
"Unable to connect to server LMS_PRD Server Msg 17 ... SQL server does not exist or access denied"
Client network utility shows server alias - LMS_PRD, TCP/IP, CL3LMS_PRD,10051
[I can connect to other SQL 2005 servers OK from this same server using this same method]
On this box, when I do telnet CL3 10051 , I get "Connecting to CL3...Could not open a connection to host on port 10051 : Connect failed"
[When I do a similar one for another SQL 2005 box, "telnet U01 10051", it connects fine]
From another SQL 2005 box - when I try to register the server, I get
"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: TCP provider, error 0 - No connection could be made because thew target machine actively refused it.) (Microsoft SQL Server, Error: 10061)"
IN the SQL native client configuration it shows alias name - CL3LMS_PRD, server=CL3LMS_PRD, protocol tcp, parameters 10051
Again if I do telnet CL3 10051, I get the error above.
From this same box I can register another SQL 2005 server without any problem and do the telnet to it OK

Hi!
I've a computer with W2K SP4 installed. Previously SQL Express 2005 worked but according to the user it "just stopped working".
When selecting database on the server in the "Data Link Properties"-window he is given the following error message:
"Microsoft Data Link" "Login failed. Catalog information cannot be retrieved"
followed by
"Microsoft Data Link Error" "Connection failure"
Note: He is not given the error message "Server does not exist or access denied!"
- The SQL service is started (can be stopped and restarted without problem)
- I've re-installed SQL Express.
- I've checked and is certain the server name is correct (i.e. computernameSQLEXPRESS)
Any ideas here because I'm getting desperate?
Thanks in advance,
Peter Hartlén

SQL 2012. I am working in understanding more the feature <AlwaysOn>. I have already worked with FCI (Failover Cluster Instance) and I would like to understand more about <AlwaysOn>.
Browsing internet/documentation I am getting more knowledge about <AlwaysOn> but a doubt persists:
1)Â Combination of FCIÂ + AlwaysOn (2 SQL servers for FCI providing cluster instance: SQLClusterSQLReporting + 1 SQL server (at least) for <AlwaysOn>: SQLAOn/SQLReporting)
If the FCI instance is called SQLClusterSQLReporting, all the connections are mapped to this name.
But if the<AlwaysOn> feature is added to the system, in case of failure the name of <SQL Instance AlwaysOn> must be used therefore I am obliged to re-map all my connections to  SQLAOn/SQLReporting.
QUESTION: IS it correct?
If yes, I do not understand the usefulness for the <AlwaysON> feature that lead to re-map all the connection.
In my opinion it should be a <MAIN> SQL Instance covering both <FCI> + <AlwaysOn>.

I unable to setup a linked server on sql server 2012. The destination server is on sql server 7.0.

More and more often, I am seeing this error message in RS subscriptions. I would assume it means the IIS server can't connect to the corporate exchange server. However I was wondering if there is some timeout setting/configuration in RS or the IIS server (or any other kind of setting) I can change to help alleviate this problem.
Has anyone else experienced this? Or know how to fix it?
Thanks,
Jeff
UPDATE: After looking closer at the subscriptions, I have noticed that subscriptions set up by a RS Admin (who is also a server admin) seem to be working fine. It is the subscriptions that are set up by ordinary users that are failing...

I have started getting this error since a week now when I try to schedule a report or change a schedule of a report. An error occurred within the report server database. This may be due to a connection failure, timeout or low disk condition within the database. (rsReportServerDatabaseError) Get Online support For more information about this error navigate to the report server on the local server machine, or enable remote errors..
We have SQL Server 2008 installed along with SSRS running on the server. I have never seen this happening before for almost a year now but suddenly it appeared.  Along with this, report subscription is also messed up and some report are not been emailed as they have a error like..Failure sending mail: An error occurred within the report server database. This may be due to a connection failure, timeout or low disk condition within the database.Mail will not be resent.Â

I apologize in advance for posting yet another connection failure issue. I went through quite a few posts and could not find the actual answer so here is the issue. I have a main SSIS package to call five other packages. This seems to work fine in my BIDS workstation; however, when I copied it, including the bat file that was created by dtexecui utility, to the production environment (which runs on 64 bit - probably has nothing to do with the 64 bit platform), the main package executes fine but the child packages failed with this error:
Description: An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult:
0x80004005 Description: "Login timeout expired".
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult:
0x80004005 Description: "An error has occurred while establishing a connection
to the server. When connecting to SQL Server 2005, this failure may be caused by
the fact that under the default settings SQL Server does not allow remote conne
ctions.".
It seems that the child packages are still using the old connection strings from my workstation. My question is how can I pass the connection string from the batch file to all the child packages that the parent (main) package is using.
Thanks,
Andrew
