I have absolutely no problem connecting to my SQL 2008 database remotely when using RazorSQL. However, I have never been able to connect successfully when I try connecting via SQL Server Management Studio.

Please see that the string did’nt come up properly when I used less than and greater than symbols…

Server name = servername,portname

Thanks to SL.Kwok.
I was searching for the right string format to give in ‘Server name’.

, worked for me.

Who would expect to give a ‘comma’ instead of a ‘colon’

Greetings,

This article helped me solve a connection problem to SQL Server 2005 installed on Windows Server 2008 R2

I added the sql service executable SQLSERVR.EXE located in the SQL Server folder to the firewall exception list and it worked just fine.

Thanks for the help

What kind of Authentication are you using in your connection string and in your IIS for that published Weblink ?

Please provide more details.

Here’s a definite way to solve this problem.
Open SQL Server 2008
At Server name select ‘browse for more’
Go to Network Servers and select the listed server(which would be like [URPCNAME]/[INSTANCENAME]).
Connect using Windows Authentication mode and u are done!

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) (.Net SqlClient Data Provider)
