frsevent error

If I am running DcDiag then I am getting the below error message:

Starting test: frsevent
Group Policy problems.

......................... RLPBW2K3ORG2 failed test frsevent

What should I do to find out the cause of this problem and how can I repair this problem? I am running Windows 2003 server. Replication seems to be working properly but GP does seem to be having some sort of problem ar some sites. Any ideas? Thanks
