Background: Windows/exchange 2003 servers across 2 uk sites
Domain / Top of AD = abc.com
southampton site = abc.abc.com
London site = abchq.abc.com
Some of the users at the abc.abc.com site are not visible to the users at the abchq.abc.com site - however most are!
Emails get through to the missing users, so thats fine, they just do not appear anywhere in the GAL at the abc.hq end. In AD users and computers there is no trace of these users. However the people that administer the abc.abc.com can see these users in their AD users and computers and in their GAL.
Any help would be greatly appriciated
