Unable To Connect To An Existing SQL Express DB But No Idea Why?

Feb 6, 2008

Within SQL Express 2005 running on Windows server 2003 using asp.net as the interface

This Is the Situation, at first i recieved this error
"

Previously we received a €œfailed to generate a user instance of SQL due to a Failure in Starting the process for the user instance. The connection will be closed€?

I looked up this error and it seams to be a flaw/bug in sql server express the error occurs because of the use of remote login on the windows 2003 server.

The solution to this was to delete an sql server directory that resides here
C:Documents and SettingsUSERNAMELocal SettingsApplication DataMicrosoftMicrosoft SQL Server DataSQLEXPRESS.

This indeed solved the failed to generate a user instance once the server was re-started however now I get a responce within the asp.net pages (which will have been built into those pages)




Your login attempt was not successful. Please try again.



now i have checked the simple errors caps lock etc and tried to log on to the SQL pages directly on the server with exactly the same result. the system was built by somone else and has not been modified "intentionally" just recently i added a few extra databases to the same server location, could this have caused the problem. to my knowlage (e.g i cant recall changing any settings)


there are one or two extenuation circumstances just recently the whole file directory was transfered from one HDD to another and then back to it's original position now i dont think this altered data but possibly there is some inbuilt security or something, i would most sincearly appreciate any questions or answers about this possibly things i havent mentioned that you need to know, just let me know i will get back to you



thanks in advance

Sql Server Express And VB.net Express - Unable To Connect...

May 31, 2007

Hi!

I'm trying to connect a DB in SQL express with a program in VB.NET Express. I'm using the Data Source Configuration Wizzard. When I select the file (.mdf), the following message appears:



Unable to open the physical file "path to my file". Operating system error 5: "5(error not found)".

An attempt to attach an auto-named database for file 'myFile' failed. A database with the same name exists, or secified file cannot be opened, or it is located in UNC share.



I'm using the Windows authentication for this, but if I try with the sa user, I get the following message:



Failed to generate a user instance of SQL Server. Only an integrated connection can generate a user instance. The connection will be closed.



Any ideas to solve this?



Thanks

Unable To Connect .NET To SQL Express 5!!!!

Feb 10, 2008

Cannot someone please help me with following problem.  I am trying to create a program to update a sql datbase from.NET 2003.  I am doing this by using SQL Server Express 5.  The problem is, is that when I run the program and click the button to view the table in SQL Express 5 I keep getting an 'System.NullReferenceException' and the table is not shown. When I look at the debug details it says that 'object reference not set to an instance of an object'.
Am not sure where am goin wrong as the connection is opened to the local server in SQL Express and I have created a connection object and initialised it to the address fo the datatable in SQL. 
Please find below the code I am working on which shows the connection string in question and the table being called in button 6  which causes the exception.
Any help would be greatly appreciated....thanks

Unable To Connect To Mssql Server Using Sql Express

Oct 13, 2006

Hi,

I installed Sqlexpress server 2005 and am able to connect to the server using the sqlexpress manager.

The connection parameters are:

server: 127.0.0.1 (This is an alias name pointing to TMD03SQLEXPRESS)
username:sa
password:test
mode: sql server and windows authentication mode
TCP/IP : enabled and listening on port number 1433.

But I am not able to connect to the server using PHP's mssql_connect function.

I tried various combinations like

mssql_connect("127.0.0.1","sa","test")
mssql_connect("local","sa","test")
mssql_connect("localhost","sa","test")
mssql_connect("TMD03SQLEXPRESS","sa","test")
mssql_connect("127.0.0.1,1433","sa","test")

but none of them works. I also tried OSQL and SQLCMD and they don't work either. They give me the following error message.

[SQL Native Client]Named Pipes Provider: Could not open a connection to SQL
Server [2].
[SQL Native Client]Login timeout expired
[SQL Native Client]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.

Can anyone please let me know what am doing wrong here?

Regards,
Celia

[Express 2005] Unable To Connect To Datasource

Aug 21, 2006

I've never used SQL Server before. I installed VB 2005 Express (I've been working with VB since I was 16), and SQL Server 2005 Express.

I installed the server with all the default settings and created a small database to handle customer information (a remake of some Access and Oracle databases I've made before).

I'm told, however, each time I try to connect to the database via VB, that SQL Server isn't accepting remote connections...

Remote? It's on a local computer. So is VB...what is going on here? Is there a setting I've missed?

Unable To Connect To SQL Server Express Locally Or Remotely

Jun 22, 2007

I have read all of the posts regarding this subject as well as 3"Dummies" guides and I keep having the same problems. I have a verysimple multi-user application that has to hit a database. Wecuerrently have this system deployed and it is working fine on adomain based network. We are scaling back and the network we will beusing is now a workgroup not a domain.It should be simple. I have XP boxes (clients) trying to hit the SQLServer Express database on a Windows Server 2003 machine. It is aclosed network so security is not an issue. I am trying to make thisthing wide open. All I want is for the user to be logged in on hisclient machine, run the application, and access/update the databasewithout having to re-authenticate to the SQL server. I want windowsto handle all of the authentication between the XP machines and theServer 2003 machine.Any suggestions would be greatly appreciated.

Unable To Connect To Sql Server Express From Virtual Folder

Apr 11, 2008

My situation: I have one virtual folder on a customer's server that hosts a web service which connects to Sql Server Express. This has been working for months.

The connection string that i use is:
(obviously the names have been changed to protect the innocent)
User ID=auser;Password=apassword;Initial Catalog=acatalog;Data Source=0.0.0.0SQLEXPRESS

I have recently added another virtual folder to the server, and it needs to connect to the same sql server. In this case it is a "regular" web site. I have it set up to use the same connection string as the web services site ( I can't think of any reason why it wouldn't be the same), however when I try to open the connection ( when I call mySqlConnection.Open(); ), I get get this error:


"SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified"

I am stumped as to why code in one virtual folder has no problem, while the other does. Both virtual and physical folders are on the same machine, and the Sql Server Express is installed on that machine.

The server is a MS Windows Server 2003 machine.

More details as requested.

Thanks,
Kirk

Nov 19, 2006

Getting error 1326.

I'm running SQL Express on Server 2003 SP1 (workstation - although, I did dcpromo promote and demote prior to installing SQL Express).

I'm trying to connect from SQL Studio Express on Vista.

TCP and Named Pipes are selected in Surface Area Config; sp_config remote, access..., 1 was run (per KB); ports 1433 & 1434 are open (I think 435 also was opened when I ran the KB instructions); Mixed mode is selected, user is set for SQL Auth, password is correct; all permissions are granted.

I found an article online which stated that mixed versions of MDAC can lead to the problem. The server has 2.82.1830 and the client has 6.0.5600.16834. Could this be the problem? If so, how to solve?

Thanks, John

What could be the possible reason for this and how can i configure sql

Unable To Use SSMSE To Connect To SQL Express Server On Secondary IP Address

Apr 28, 2006

I am having trouble to use SSMSE to remotely connect SQL Express server using IPs other than the base IP of the machine.

Machine settings:

(1) Has multiple IP configured. Those IP are accessible remotely

(2) Firewall is not on.



SQL Express server configuration:

(1) TCP/IP and named pipe are on



Browser service state:

(1) running

(2) listening at 0.0.0.0:1434 (UDP)



SSMSE connection results:

(1) with <baseIP><instance>, connects OK

(2) with <otherIP><instance>, connection failed.

Both connections use exactly the same authentication information.



Testing results using telnet:

(1) telnet <baseIP> 1434, OK

(2) telnet <otherIP> 1434, OK



Does SSMSE actually only listen on the base IP even it shows to listen on all the IPs?

Unable To Connect Remotely After Upgrading A SQL Instance From Express To Enterprise

Mar 4, 2007

Problem: I upgraded a SQL Server Express instance to SQL Server Enterprise, but I'm unable to connect to the SQL server from any remote machine. Only local connections work -- and I've verified that Remote Connections are allowed in the SQL Surface Confg. utility.

Scenario: Server1 has an SQL Enterprise edition installed as a default installation. SharePoint Server 2007 was installed later, and during that install a SQL Express edition instance was installed which is part of the standard SharePoint install. That Express instance contains all the SharePoint content databases.

So Server1 has SQL instances:
Server1 <default install running Enterprise>
Server1OFFICESERVER <previously running SQL Express, now upgraded to Enterprise>

After upgrading Server1OFFICESERVER to Enterprise, everything seemed to work fine (i.e. SharePoint works fine). However when I try to connect remotely to Server1OFFICESERVER I can't. I've verified through the SQL Surface configuration tool that remote connections are allowed. I've rebooted the server as well. I've tried connecting remotely using various PCs and various applications (e.g. SQL Server Mgmt Studio, Visual Studio, etc.).

Any other ideas to try?

Visual Studio 2005 Unable To Connect To SQL Server Express 2005

May 26, 2008

Hi,
I have VS Pro 2005 and SQL Server Express 2005 installed on an XP Pro machine. When using VS 2005, in the 'Server Explorer' window I can see and attach to two SQL Server databases that I have set-up. But if I attempt to access the same databases from withn the 'Solution Explorer' window I get the following dialog box message,

"
Required Component Missing (Dialog box heading)

Connections to SQL Server Files (*.mdf) require SQL Server Express to function properly. Please verify the installation of the component or download from the URL: http://go.microsoft.com/fwlink/?LinkId=49251
"

I have uninstalled and then reinstalled both VS 2005 and SQL Server Express twice but it has helped.

I don't understand why I'm getting this error because all of the server configuration tools and connection utilities seem to work fine but VS say's that SQL Server Express is not installed.


Thanks,

CLN

P.S.
I had another application that required MSDE 2000A to be installed. When I removed the other application I also removed MSDE 2000A and that's when the problem began.

Import Existing Database Into SQL SERVER EXPRESS Management Studio Express

Feb 18, 2008



Hi,

I am a newbie so i apologies beforehand for any mistakes i make on this forum.
Anyway, i created an asp.net website using the MS Visual Web developer tool. This has a couple of SQL SERVER databases within it.
I then latervinstalled the SQL SERVER management studio express in order to manage the SQL SERVER DBs that i had as part of my website but they do not appear within the management studio db list.
As this is the express version, is there anyway of importing the existing SQL SERVER dbs that i have to the management studio so i can manage them from there?

Unable To Drop Login Due To Existing Event Notification

Aug 20, 2007

Hi

I am unable to drop the above login. The error is Error:15141 The server principal owns an event notification and cannot be dropped.

I have looked in the table sys.server_event_notifications and there are rows returned that have a server_principal_id of the user I am trying to drop. No events have been created on this server, so I am assuming these notifications are either created by default or are somehow related to Database Mail?

All the event notifications belong to service name "SQL/Notifications/ProcessWMIEventProviderNotification/v1.0" and begin with SQLWEP (i.e. SQLWEP_RECHECK_SUBSCRIPTIONS, SQLWEP_B415ADB8_A604_4057_976F_600002FA5AF6). How can I find out what these are for and how they were created?

What purpose do these event notifications have? Is there some syntax to change the owner of these event notifications so I can successfully drop the login? If the only way is to directly update the system view, is this safe and what repercussions could this have?

Thanks
Martin

Cannot Connect W/ Java App But Can Connect W/ .Net App - SQL Server Express 2005

Dec 12, 2006

I'm having a problem connecting with a Java application but I CAN connect using my .Net application - the user name and password are the same for both (using the same database on SQL Server Express 2005).

The error I get is: "com.microsoft.sqlserver.jdbc.SQLServerException: Cannot open database "CORNERS" requested by the login. The login failed." An interesing note - I get the same message if the database is not running.

SQL Server Express 2005 is installed in mixed mode.

Here is my connection string in the .Net appplication: <add key="connectString" value="Server=(local);UID=sa;PWD=myPasswd;Database=CORNERS" />.

These are my values in my Java app web.xml -

<init-param>
<param-name>DBDriver</param-name>
<param-value>com.microsoft.sqlserver.jdbc.SQLServerDriver</param-value>
</init-param>
<init-param>
<param-name>DBURL</param-name> <param-value>jdbc:sqlserver://localhostsqlexpress:1055;databaseName=CORNERS</param-value>
</init-param>
<init-param>
<param-name>DBUser</param-name>
<param-value>sa</param-value>
</init-param>
<init-param>
<param-name>DBPwd</param-name>
<param-value>myPasswd</param-value>
</init-param>.

And yes, the port is 1055 - I checked to find it.

I am using Microsoft SQL Server 2005 JDBC Driver 1.0 (sqljdbc_1.0.809.102).

Does anyone have any idea what is wrong so that the login fails in the Java application but works in the .Net application?

Unable To Re-create Snapshot Of Existing Publication Due To Missing Publisher's Identity Range Allocation Entry

Jul 21, 2006

I re-created a publication that was having problems and it gives this error when I start the snapshot agent from SQL Server Management Studio:  I am stuck on how to resolve - any ideas?

"The publisher's identity range allocation entry could not be found in MSmerge_identity_range table.  Transaction count after EXECUTE indicates that a commit or ROLLBACK TRANSACTION statement is missing.  Previous Count = 1, current count = 2."

select * from MSmerge_identity_range returns 19 entries but I don't know how to fix. 

I have tried deleting and re-creating but always get this error.

My other publications and subscriptions are working fine and I was able to create a new test publication that worked but can not get this one to work that worked fine up until today. 

 Any ideas?

Unable To Open A SQL Express DB Created In Visual Basic Express

Dec 14, 2007

When I start Management Studio I get the following message and a suggestion to change a setting:
(I can choose to continue and the system databases appear, but the DB I created does not.) 
 "Unhandled exception has occurred in a component in your application. Cannot create a stable subkey under a volitile parent key."
 
 ************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
Any assistance is appreciated.

Unable To Re-install SQL Server 2005 Express And Also SQL Express Toolkit

Jul 28, 2007

Hi,


I had some issues on my server and had to uninstall .Net Framework 2.0, SQL Server 2005 Express, and SQL Express Toolkit. I installed SQL Server 2005 Express and it seemed to be ok.


Then my problems all started when I tried to install SQL Express Toolkit because I needed to install DTS Wizard again, and it errors out and wouldn't let me install it. So I uninstalled everything that's listed above again.


I then tried to install SQL Server 2005 Express again, and on the second from last screen, while its listing all the components and configuring them, I get the following error as it's configuring the last component... which was the SQL Server Database Services.


TITLE: Microsoft SQL Server 2005 Setup
-----------------------------------------------------------
The SQL Server service failed to start. For more information, see the SQL Server Books Online topics, "How to: View SQL Server 2005 Setup Log Files" and "Starting SQL Server Manually."


I tried to re-install the SQL Server Express another 7 times wth no luck.


If anyone can point me in the right direction I'd really appreciate it.


Thanks,
Bill

Unable To Connect To DB

Nov 27, 2006

Hello everybody
I wrote a vb.net win app that uses a mssql 2005 express DB.
On my localcomputer everything worked without a problem.
Now I wish to deploy my app on a remote computer (that has mssql 2005 express installed), so. I added an app setup project to my project using the vs2005 setup tool, installed the app on the remote computer, and copied the mdf file to the remote computer.
I'm able to see the DB through the remote computer mssql manager, But when I try to start the app on the remote computer I get this error massage :
A connection was successfully established with the server, but then an error occurred during the pre-login handshake. error: 0 - No process is on the other end of the pipe.)
my connectionstring (in the config file) looks like that :
    <connectionStrings>        <add name="Info_Manager.My.MySettings.MaxinetConnectionString"            connectionString="Data Source=DOTAN-XPSQLEXPRESS;AttachDbFilename=C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataMaxinet.mdf;Integrated Security=True;User Instance=True"            providerName="System.Data.SqlClient" />        <add name="Info_Manager.My.MySettings.MaxinetConnectionString1"            connectionString="Data Source=DOTAN-XPSQLEXPRESS;AttachDbFilename=C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataMaxinet.mdf;Integrated Security=True;User Instance=True"            providerName="System.Data.SqlClient" />    </connectionStrings>
by the way changing the user instance attribute to "false" didn't help.
Does anybody know how to fix this problem.

Unable To Connect

Apr 1, 2002

Everything has been working fine our SQL Server (lets call it Server A) (v2000 under NT 4), however sometime over the weekend it is unable to connect to one of our other SQL Servers (Server B).

In the Event Viewer I found this error:
SuperSocket info: Failed to get Exclusive port use(MSAFD Tcpip (TCP/IP)): Error 10013.

Everything on this server appears to be working fine, as in everything can connect to Sever A that needs to, but Server B can't connect to A, nor is it working the other way.

Also, Server A SQL Services run on port 2006, and B is on the standard 1433. Everything has been working with this up until today?

Any ideas?
Thanks!

MS SQL 6.5 Unable To Connect.

Jul 23, 2005

Let me start by saying that, yes we know v6.5 is no longer supported byMicrosoft and that moving to SQL2000 might resolve our problem.Actually the migration to SQL2000 is 1 to 2 months out and in the QAphase now. Unfortunately we need to resolve the current 6.5 issue nowas it heavily impacts a major revenue stream for the company with everyoutage we encounter.The Problem:At least once every 24 hours the SQL Server begins disallowing new userconnections. When this happens the 2 CPUs begin to thrash. About 5minutes later the error log begins to print out the following errormessage: "Unable to connect. The maximum number of '500' configured userconnections are already connected. System Administrator can configure toa higher value with sp_configure." No new connections can be made to theserver; however, the existing connections continue to function normally.We never see anywhere near 500 user connections in the system (it tendsto average around 350 connections). If we begin to disconnect users theserver continues reporting that the maximum number of users isconnected. Eventually running queries thru an open connection will hangand we have to resort to a hard reboot of the server as neither SQLServer will not shutdown nor will the operating system.The Server:Compaq Proliant DL380 with dual 863 MHz. processors (x86 Family 6 Model8 Stepping 3 GenuineIntel), 917,020 KB of physical memory, MicrosoftWindows 2000 Server (Version 5.0.2195 Service Pack 4 Build 2195), TotalVirtual Memory 3,138,688 KB, Page File Space 2,221,668 KBSQL Server:Microsoft SQL Server 6.50 - 6.50.479 (Intel X86). Some pertinentconfiguration settings: memory - 244100 (in 2K units), user connections– 500, RA worker threads – 3, max worker threads – 255We found one reference to the above error message in the MicrosoftKnowledge Base and that refers to a condition where the server has 2GBor more of physical memory with 1.5GB assigned to SQL Server. This doesnot pertain to our situation. Have any of you ever encountered thisproblem?I appreciate your insights.*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
