A recent migration of over 1500 Active Directory user accounts involved handling deep file names and other file issues. We had to use a number of scripts to solve those issues, and also used LDAP queries to identify which users with Exchange mailboxes were disabled in the Active Directory.

We have also just solved some problems for a client around Active Directory replication across more than 30 sites where a hub site had suffered a catastrophic disaster. Matters were complicated by a custom replication topology, but all problems were put right in good time.
