Hi Ramesh Sir,

i have installed SQLTest in my laptop and there is default instance of sql server and named instance of sql server in my laptop.
i have changed the connection string to point my named instance but the connected is failing with the below error message.
So as work around i have disabled the firewall checked the browser service and the network protocols. and they are fine.
it is not able to connect even to default instance on my laptop.

Could you please help me on this.

Error Message.

Hello Madhu

Are you able to connect with SQLTest to the default instance?
Are you able to connect to the named instance from SQL Server Management Studio?

Normally this should work fine, can you paste your connection string masking out server name, user name, password etc.

Best Regards
Ramesh
