Sorry for my last post i mistaken not the references. if you try using web.config it you using asp.net project. Im also experience with same error when i try to connect my Sql server 2005 standard Edition.

step 1.
try to check Sql server if you are using this configuration Servername:192.168..\databaseschema
username:xxx
password:xxx

step 2.
{Server side sql server Standard Edition}

locate Sql server Configuration Manager
- Protocols for mssqlserver
-TCP/IP ,Enabled
-Name Pipes, Disabled

Sql Native Client Configuration
-TCP/IP , Enabled
-NamePipes, Enabled

step 3. Web.config {webservice project}

——————————————————————————————-
{ Possible cause of error’s }

——————————————————————————————-

servername configuration server = 192.168.0.8;uid=…etc
is defferent from server = 192.168..\databaseschema;uid= .. etc

Correct me if i mistaken. thanks

pls give reply to this error

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server)

I have followed the steps demonstrated in this article but I have yet to find where the problem lays with my situation.
Here is the error I am getting:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 – Error Locating Server/Instance Specified)

Perhaps it is addressed here but being a novice with this kind of stuff I haven’t seen it.

Thank you if you can shine a light on this problem.

thanks Vince! enabling inbound port 1433 and forcing sql server to listen to that port instead of dynamic solved it! thanks again.

thanks. I was searching for the solution of error 10061 for hours. My mssql server was stopped and works fine after I initiated mssql server. I feel like so dumb now.
thanks.

Mr. Dave – Thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you!

your fix provided the tip to allow the sqlbrowser.exe thru the firewall. i’ve only been looking for this resolution for…um…a couple of weeks now. Your Fix worked with 2008 R2 & SQL 2012 RC0 – that I was trying to access via Office 2010 Access database front end.

Happy Holidays

Hi,

The servers need to have Static IP. Because we tried to connect this server from the outside not in the same network.

Please advise.
Regards,
Mike

I followed your steps, but still couldn’t attach. Found elsewhere to check the port number SQLExpress was using. Turns out SQLExpress was using dynamic ports. I forced it to use 1433, and (including all the above instructions), could finally connect. Yeah!

I’m a programmer who’s usually admin-challenged especially when it comes to networks, protocols, ports, and yet I really didn’t have any trouble getting all my SQL servers set up and all accessible from a workstation-hosted copy of Management Studio.

Now, making sure they are using the strongest security best practices, that’s a topic for another day…

Hello Mr. Dave
This is the first time i am sending a post to you. But I always follow your advices. your advices helped me lot when no one was near me to suggest.

today i faced a problem that when i want to connect to sql server 2008 on the windows server 2008 then in the udl file the server name is showing but when i connect through windows authentication or sql authentication then it is giving me an eror as sql server doesnot exist or access is denied.
but when i tried from other pcs i can connect to the database and my windows application is working fine.
all the pcs are in the same network and in the same domain also.
but why then the problem is only for this 1 pc only.
i checkd all the issues above which you suggested me but also the same problem.
please guide me.
