SQL Server 2005 Remote Connection Not Allowed Error 26
Jan 11, 2008
Help! My web-application worked fine last week. I have made some enhancements and it still works fine when I test in locally in VS 2005 and from IIS when I allow unauthenticated users (by commenting out "<deny users="?"/>" in my web.config. However, with not allowing unauthenticated users, I get redirected to a login application (which also worked last week), where I supply one of several user names and passwords and it is supposed to redirect me back to my default.aspx page. Only, now it is taking the authentication parameters from the login screen but is not redirecting me back to my app's page and instead is putting up this Error 26 that states SQL Server 2005 does not allow remote connections.
The included stack trace has no information about what server it seems to be trying to connect with, but the strangest thing about it is I/we are not using SQL Server 2005 yet (still a future upgrade not too far off). The application database, the authentication aspnetdb database, and the Session aspstate database are all on the same SQL Server 2000 managed server. And, these were all working last week (and are all accessible). I have not changed any connection strings and as I said, it works fine without the loging in part both locally and from IIS. It is only when using the Login in application, which is working with other apps and the developer insists the problem has to in my application (after all the first line of the error message states: Server Error in '/deployment1' Application, which is my app!)
I am lost in finding the culprit, can someone please give me some ideas?

HiI'm going insane.I have a club starter kit on my local server which is working fine.I have migrated the database to my remote host and seems to have transfered ok.For a brief period I was able to connect to the database remotely, but now I cannot I get the following, even though SQL Server Surface Area Config is set to accept remote connections.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 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)This is my connection string;<add name="ClubSiteDB" connectionString="Data Source=xx.xxx.xx.xx,xxxx; Network Library=DBMSSOCN; Initial Catalog=tets; User ID=sqladminbob;Password=sqlbob4398;" providerName="System.Data.SqlClient="/>I hav also tried to use aspnet_regsql.exe to add the remote provider but I get the same message. Thanks

Just installed SQL Express but cannot connect since it says Remote Connections are not allowed ! This worked before. I have tried different protocols and even SQL Authentication. No luck here and I've been up all night...

I have a form to submit some data to a database located in the App_Data folder. I have the following connection string:
<connectionStrings>
<add name="ConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Siven.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
On the form I'm using a DetailsView control and using a SqlDataSource as the datasource, pointing to the above connection string. In realtime, when i submit the data, I receive the following error:
Server Error in '/' Application.
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
I'm using discountasp.net as the host, and I did not elect to use the SQL Server databases, I'm just going to use SQL 2005 express. I dont understand why it's not pointing to the db when it's there (and to make sure, I re-uploaded). Is there something I missed here?

My site works fine in VWD2008 express, but I get this error when I try to use it on my live website.
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.
According to this article: http://support.microsoft.com/kb/914277 I am supposed to:
1.
Click Start, point to Programs, point to Microsoft SQL Server 2005, point to Configuration Tools, and then click SQL Server Surface Area Configuration.
Ok, there is no such program in this folder. The only thing in there is "SQL Server Error and Usage Reporting"...
The other thing I am greatly concerned with is this: All is want is for my webpages to be able to access my database for user authentication. I DO NOT want to grant the internet rights to remote connect to my database.

I get the following error and have been trying to figure out why I keep getting it. Initially, I had placed my project under wwwroot folder and ran it under IIS and it gave this error. Then I moved it to my local C drive and same thing. I am sharing this project with two other co-workers and all our config files and code files are same...they don't get this error but I do. I checked that SQL Server Client Network Utility has TCP/IP and the 'Named Pipes' enabled. I thought maybe I have setting in the Visual Studio 2005 that I'm not aware of that's causing this problem...it can't be the server since my co-workers aren't having this error and can't be anything in the code since all of us are sharing this project through vss. I dont' think using different version of .net framework can create this error. I changed the version from 2.0 to use 1.1x and it gave same error... Any help would be greatly appreciated. Thanks in advance.

Hi
I have a simple FTP task that I am trying to connect to an FTP server. I can test the connection fine, however, when I try and execute the package from Visual Studio 2005 I get the "The Password was not allowed" message. I have found some threads that mention setting the protection level on the package to EncryptSensitiveWithPassword, however, I still get the same message appearing.
Has anyone any idea as to what is causing this and how I can get around it
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.

I'm using SQL Server 2005 version 9.00.1399.00, not the Express version. Should I update the SQL Server 2005 Network Configuration in SQL Server Configuation Manager? But I don't know what should be set to "Enable" or Disabled". Is any other place need be configured?
Thanks.

This has probably been answered before, but...
I have a local SQL Server 2005 instance running, and I would like to have another user on my network connect to this instance. However, when he tries to connect, he always receives the same error message:
"An error has occured 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: SQL Network Interfaces, error 28: - Server doesnt' support requested protocol)"
So, I checked the properties for the server, and under the connections tab the allow remote connection box is checked.
Any clue where to look next?

Its been almost 2 months i start running a test script page to check if i made the remote connection until now its getting worst.
I did follow every bit of the instruction and pre-evaluation in fact the script is working locally with this string:
cn.Open "Driver={SQL Server};" & _
"Server=global-static-ip;" & _
"Address=local ip,1433;" & _
"Network=DBMSSOCN;" & _
"Database=testdb;" & _
"Uid=xx;" & _
"Pwd=xx;"
i also review the ff post for client and server trouble shooting tips:
http://blogs.msdn.com/sql_protocols/archive/2006/09/30/SQL-Server-2005-Remote-Connectivity-Issue-TroubleShooting.aspx
surface configuration, sql browser, firewall exemption...
and nothing seems change when i access the uploaded script.
is there anything i am missing?
by the way the script is uploaded by company.

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?

Hi,
I installed SQL server 2005 express edition on my windows server and I had no problem with connecting it remotely through Management Studio, then I removed it and installed a full edition SQL server 2005. That's when it's gone all wrong.
Now I can't remotely connect the server through Management Studio. The error I get is the same as some of the people in this forum has which is:
"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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)"
The problem is that I have all protocols enabled and even when I disable firewall and unassign all the ip filters still no go.
I looked at te machine.config file at my server and the connection string bit goes like this:
<connectionStrings>
<add name="LocalSqlServer" connectionString="data source=.SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/>
</connectionStrings>
Can anybody tell me wether you think the problem lies here where it says SQLEXPRESS where I actually have Sql Server 2005 installed.
I've been in and out of every documentation regarding this but they all tell me to configure the protocols and nothing else which doesn't really help.
I have tried running .Net Sql server wizard on the server but it didn't connect probably for the same reasons why I cant connect remotely.
I would really appreciate any help
Thanks

I am using MSSQL Server 2005 Express Studio and tryig to connetch to the remore server but does not work.
I get this error.
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.
Though I have read like child and made changes according to it.
http://support.microsoft.com/kb/914277
Still says same error.
I am clueless how to do it.
Do any one know web based mssql editor where i can connect mssql?
Thanks in advance.

I have a SQL Server 2005 database (called BDHSE) in a PC which i call PC1. I have a second PC (PC2) and both are within a network (a WLAN).
What i want is to have access to BDHSE from an application in VB6 (APP1) running in PC2. All the INSERT, DELETE, UPDATE records process is done through APP1.
APP1 ia currently running in PC1 and is to be installed on PC2.
I have these questions:
1. What do i need to install in PC2 since all the INSERT, DELETE, and UPDATE is done using APP1? I guess i only have to install the Microsoft SQL Native Client (with all the prerequisites of course) but i am not sure.
2. In the APP1 made in VB6, do i have to change the connectionstring since i am accesing the database which physically is at PC1 and the APP1 will be used in PC2?
3. Any advice you can give me on doing this will be well received.
Thanks in advance,
BSc Fernando Martinez

hello there! i have a problem importing data from a remote connection using Sybase ASE ODBC driver(the sybase odbc driver is the only way we can access the database from the remote connection, we've already tried this in crystal reports). in the sql server import export wizard i chose the .net framework data provider for odbc. then below the wizard requires the following info: the connection string, DSN and driver. i specified the correct driver and dsn. in the connection string i specified the user id and the server name but it still produces error. the error says:
the operation could not be completed.
additional information:
ERROR[01000][SYBASE][ODBC Sybase driver][Sybase]ct_connect(): user api layer: internal Client Library error: HAFAILOVER: Trying to connect to server.
ERROR[01000][SYBASE][ODBC Sybase driver][Sybase]ct_connect(): user api layer: internal Client Library error: HAFAILOVER: Trying to connect to server.

I have a Rounding error: Between flat file connection manager Source & OLE DB Connection Destination (SQL Server 2005) in my Dataflow.
File looks like this lets call column names Col A,B,C,D
70410000 RD1 1223631.92 196042.42
70329000 ICD 11025.84 3353.88
71167300 COL 104270.59 24676.96
flat file connection manager settings: first row Column names then Advanced tab Col A float , Col B float , Col C string ,Col D float ,
OLE DB Connection Destination (SQL Server 2005)
CREATE TABLE [dbo].[PT_CUST_ABR](
[PARTY_NO] [float] NULL,
[PARTY_NAME] [varchar](75) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[TELECOMABR] [float] NULL,
[GENIABR] [float] NULL,
Problem: ColA (Source) Rounding error to PARTY_NO (Destination)
I have a field of text of in a flat file that the flat file connection manager Source picks up correctly €ś70000893€?
However when it gets the OLE DB Connection Destination the data has changed to 70000896. That€™s before its even Written to the database.
The only clue that something is wrong in the middle is the great Data viewer shows the number as 7.000009E+07
Other clues looking at the data it appears there is a rounding error on only the number that dont end in 00
ColA (Source) PARTY_NO (Destination)
71167300 71167296
70329000 70329000
70410000 70410000
Any ideas people?
Thanks in advance

Fellow Devs,
I have an instance of SQL Server Express 2005 running on another box and I have Remote Connections enabled over both TCP/IP and Named Pipes, but on my other box I keep getting the error that the server does not accept Remote Connections.
Any ideas why this might be happening? Is there some other configuration?

When copying data to a remote SQL2K5 destination from a SQL2K5 source database, both using mixed sql server security mode, my job generates the following error:
[Transfer SQL Server Objects Task] Error: Execution failed with the following error: "Cannot apply value null to property Login: Value cannot be null..".
This occurs after the destination database tables have been truncated and replacement data from the source would begin to copy.
The same process can be successfully completed from the Management studio with a simple data export process. However, when I run the saved package again from the BI interface, I get this error.
My search engine searches have yielded numerous hits of others having the same problem with one microsoft rep indicating it was a bug and would be resolved in sp1. I am working with sp1. Oddly, there is only mention of this in the forums. No KB article from MS addresses the problem and I do not see it addressed elsewhere at sqlservercentral.
It appears that others have switched to Integrated Security and resolved the problem. However, I do not have that option with a remotely hosted database.
Does anyone have any information concerning this problem?

Hi,
I am putting this question here but I am not limiting it to sql server 2005 express edition.
I am developing an app on a local machine (winxp with sql server 2000 personal edition) however I came to find out that full-text does not work in this setup unless I use a server type machine.
This fouls up my development somewhat and I would like to know if there is
a) a work around for my sql server 200 setup
b) does full-text serach work in sql server 2005 express edition which I have installed on my PC ?
Thanks for any input on this issue.
Tuka
