Error while runnign web appication using Visual studio 2005

Hello,

I have made one application in asp.net using C#. It is running perfect in my visual studio 2005 and also on localhost.

Currently i have installed visual studio 2005 in new PC. Now that application is running fine under Localhost. But it is giving me error when i run

it through visual studio in New PC and the error is

" Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed. "

One more point is that i have used DSN and so i checked the DSN also and it is also correct.

Second thing is I have two directoryadmin anduser.If I run the pages of admin directory then it is running fine. But if i run the page of user directory then it is showing

me the above eror. I have also made different config files for both directory and one general config file for whole directory.

I have also search on google for this problem and they asked me to delete SQLEXPRESS directory from C drive but it is not get deleted and it shows the error that

"it is being used by some other program please try again."

So you might have understood my problem. Please help me to get out of this problem. Thanks a lot for reading my problem.

Regards,

Hardik B.

Well if you're looking to delete that directory, you will probably have to shut down your Mircosoft SQL Server service (control panel -> admin tools -> Services). I'm not sure if that will fix your problem though.. Also, make sure to restart your service after you finish your delete.
