Hi all, i'm not sure if this is the right place to put this post, so if anyone has an alternative place for it to go then please, suggest away.
My problem here is a database (DB1) that resides on a 2005 server with 20 other databases. Around 6pm DB1 is innacessible. Yet all the other db's are able to be accessed. Now DB1 web client is held on another server, it is through the web interface that i receive this error message. I have checked that the settings on the server i.e. Named Pipes were enabled and they are. I checked the logs and the event viewer and nothing seems obvious to the cause of the error. I'd appreciate your help on this. Thanks in advance.
Server Error in '/' Application.

Hi,
1) Please double check your connection string
2) Please make sure your DB server connects and user/pass is correct in the connection string.
If the above points are fine. Then your code should work.
Thanks
