Since implementing AD about 4 years ago we've seen a continuing thread of users needing to be deleted then re-added to global groups to get access to resources. It seems that the larger the group is the more issues we have with it. Another group issue that just appeared in the last week is that a newly created and populated group loses all of its members. The normal AD health checks says replication is hunky dorey. What should I be looking at to resolve this? Dennis
