Faulting application services.exe... faulting module esent..

Archived from groups: microsoft.public.windowsxp.perform_maintain (More info?)

Hi there,

We recently removed 5 workstations from our domain and set
them up on their own workgroup with a file share on one of
the computers serving data and the FrontRange Goldmine 6.0
application (BDE version not SQL). Since then all of the
Windows XP machines have had this message appear in the
event log 5 to 6 times a day and then reboot
automatically:

Faulting application services.exe, version 5.1.2600.2180,
faulting module esent.dll, version 5.1.2600.2180, fault
address 0x00023352.

Along with this event is the SceCli 1202 event:

Security policies were propagated with warning. 0x428 : An
exception occurred in the service when handling the
control request.

For best results in resolving this event, log on with a
non-administrative account and search
http://support.microsoft.com for "Troubleshooting Event
1202's".

And occasionally this:
SOURCE: Userenv ID: 1085
The Group Policy client-side extension Security failed to
execute. Please look for any errors reported earlier by
that extension.

These machines are all up to date (Windows XP/SP2) and
have full antivirus protection / protected by hardware
firewall / the whole works...

So.. what the hell is going on?? I can't find any
information on Microsoft's website or Google. Any ideas?
Note that one of the five machines is Windows 2000 SP4 and
seems to be fine...

Thanks,
Drew
