We are a school system with servers nw6 servers in every school at present
each school has it own tree. We are thinking of merging all the servers into
one tree.

I would appreciate feed back on the pros and cons in doing this.

Are main reason is to replicate the dns. backup
and management of one tree.

I would think some conns would be time sync issues over a wan. and Upgrading
servers (when you patch one server you need to patch all the servers at or
close to the same time to keep the ds the same)

what are your opions?
