i am using ASE 12.0 on Windows 2000

The problem i encountered when i load a database into sybase
it doesn't work giving the following error in the error log


00:00000:00010:2004/03/10 10:39:07.41 kernel Connectivity Library (Directory Control Layer) Error: Error returned by service provider.

I have restarted the backup server and it is working fine.

Can anyone tell me how and what to change in the interface file so that sybase starts working?
