WinCVS client commit displays "The current directory is invalid"

[Jon]

When I perform a commit from a remote client the following appears:

Checking in main.h;
/cvsrepo/KickStart/main.h,v  <--  main.h
new revision: 1.37; previous revision: 1.36
done
The current directory is invalid.


***** CVS exited normally with code 0 *****


Note: I'm running the following version:

Client: Concurrent Versions System (CVSNT) 2.0.49 (client/server)
Server: Concurrent Versions System (CVSNT) 2.0.49 (client/server)
