We are having difficulty prepping A.D. for an upgrade to 2003 Server R2.  We appear to be having a replication issue.  Here are the errors we are getting from adprep /forestprep:

"There is a schema conflict with Exchange 2000. The schema is not upgraded."

When we ran dcdiag /test:fsmocheck on one of the DC's... we got this error:

"Warning: DcGetDcName(GC_SERVER_REQUIRED) call failed, error 1355
A Global Catalog Server could not be located - All GC's are down."

We host our own internet DNS and our domain name was switched from AD-integrated to standard primary.  We aren't sure if this is what is causing the replication issue/errors we are getting or if it's just part of the problem.  Or... not the problem at all?

Anyone have any ideas?  We need to get this fixed asap!
