Default Domain Controllers Policy -version mismatch - EventID 1202

[DanielUK]

I've been getting EventID 1202 filling up the application log over the past couple of weeks so I decided to look into it properly. I've followed the Microsoft troubleshooting guide here:

http://support.microsoft.com/default.aspx?scid=kb;en-us;324383

and also:

http://support.microsoft.com/?id=279432

It's specifically the 0x534: No mapping between account names and security IDs was done error.

I've followed the guide and finally got from the gpo tool this output but not sure how best to interpret it:

The guide says to remove or replace the problem entry...from where exactly?

Thanks
