You don't say whether the existing domains are NT or AD domains. It can make a huge difference on a large project like this. With AD building the first DC is a crucial step and generally the solution to make changes is to rebuild the entire domain.
I think the best advice is to contact Redmond, cough up the dough, and get some of Microsoft's best engineers to analyze the situation and determine the best solution. _VT_VT_VT_VT_VT_VT_VT_VT_VT_VT_VT_VT_VT_VT_VT Todd Pukanecz MCSE, GCWN Virginia Tech, AHNR IT Blacksburg, Virginia --- The object and practice of liberty lies in the limitation of governmental power. - Douglass MacArthur > -----Original Message----- > From: Keith Beahm [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, February 26, 2002 11:52 AM > To: NT 2000 Discussions > Subject: Merging Dissimilar Domains > > > We have a situation in which we will have to merge (as quickly as > possible) 5 separate domains into a 6th one.
