not bad, especially since AD prior to 2003 (at 2003 forest functional level, which activates LVR - link valure replication) only supports roughly 5.000 members to a group, due to these version store limitations...  I doubt you can increase the storage for the version store, but an intermins solution would be to split your users into mulitple groups and nest them - then, after you've increased the FFL to 2003, re-add all of them to the original group but don't add more than 5.000 at a time.  LVR no longer has a group-size limitation, but still has the version store limitation for the changes.

Subject: [ActiveDir] Replication problem related to large groups.

 
Right now in our Active Directory environment we have 2 groups with 80,000 people or so.  I know that this is bad and we are working to fix it.  Replication was working before we tried to promote three DCs to W2K3.  Now after the promotion, we are getting errors with the Event ID: 623.  I think the replication of the large groups is the long-running transaction.  Would it help if the version store max size was larger, and if so how do I increase it?  Below is the Event Log entry I get.
 

NTDS (576) NTDSA: The version store for this instance (0) has reached its maximum size of 104Mb. It is likely that a long-running transaction is preventing cleanup of the version store and causing it to build up in size. Updates will be rejected until the long-running transaction has been completely committed or rolled back.

Possible long-running transaction:

SessionId: 0x00B705A0

Session-context: 0x00000000

Session-context ThreadId: 0x00000A78

Cleanup: 1
