Server Error in '/' Application. Hi, can you please help to get rid of this error. we are building a custom moss application where the UI built user controls. we are using SmartPart webpart to render user controls. we have our business logic as custom dll. when I was trying to do someting with my code, suddenly this error has popped up. I feel there is nothing about the database, other applications are running properly along with central admin, SSP. Also i can log into database and see things there.There is something else wrong and i am not able to figure it out. Please help me.

error is coming for PDB\Administrator account. please verify this user for database rights. check your application identity pool user also on IIS to make sure it has the proper rights on database. can you browse to any of your sharepoint site other than central admin and SSP? most probably those two are running under a different user id in application pool identity and your sharepoint web application is running under a different user which does not have rights on database.

That may not be the case PDB\Administrator is the domain admin account (within the VPC image). all application pools are running with the pdb\administrator credentials only. Yes I can browse other applications other than SSP and central administrator, where i didnt do any custom programming like user controls etc any other ideas?

Check out this post on my blog: http://greggalipeau.wordpress.com/2008/06/07/sharepoint-cannot-connect-to-the-configuration-database/ It has a link to the Microsoft article talking about how SharePoint might not be able to connect to configuration databases. Also, it has a link to a specific database issue I found once that showed up my SharePoint environment. Maybe these links will help you debug through your issue. Your issue seems to have a little different behavior than the error message these links talk about. But, the debug steps they take you through might help you uncover your specific issue. Good luck, Greg

Hello! I have exactly the same daily in 5 servers farm. "unable to connect to database". MOSS is IU1. WFEs are in DMZ, SQL in backend. No idea what it is. It happens at exactly the same time. My Network, DBA and Antivirus teams have no idea what is it. No idea from MS support. :-( Googling and Blinging does not help also. Plan to setup sniffer between WFEs and SQL tomorrow. Will see. Cheers, Alexey
