DBCC shrinkfile error - Msg 8985

Hi

I am getting following error when I try to shrink the transaction log:

DBCC SHRINKFILE (wslogdb50_Log, 2000)

Server: Msg 8985, Level 16, State 1, Line 1Could not locate file 'wslogdb50_Log' in sysfiles.DBCC execution completed. If DBCC printed error messages, contact your system administrator.

Any ideas?

Regards
