Hi all

Hope you can help me with this one.

First of all some backgound:-

This is a windows 2003 enterprise server running 2003 exchange enterprise. The server has been running fine for 6 months. It is also the DC. (Only server on the network)

I receive hundreds of the error below and the server has to be restarted to get back up and running again.


Event Type: Error
Event Source: MSExchangeAL
Event Category: LDAP Operations
Event ID: 8026

Event Type: Error

Description:
Windows cannot query for the list of Group Policy objects. Check the event log for possible messages previously logged by the policy engine that describes the reason for this.


Now this is what I have done so far:-

I have ran netdiag and dcdiag both passing ok.
I have checked the receipient update policy in system manager and the domain/exchange server/ and windows domain controller all appear to be correct.

Any help would be greatly appreciated.

Many thanks
