Hello all.

We currently have two domains (domain A = Windows 2003 at operations, domain
B = Windows 2000 at branch) joined by two-way trusts, split across a T1 WAN
connection (1.544 Mbps). The branch office has less than 120 users. We
currently have one Exchange 5.5 server at each location, configured as a
single organization, dual-site system. These two are connected using a Site
Connector and Directory Replication Connector.

We need to accomplish two things; the first being to merge domain B into
domain A (I realize that this is for another newsgroup), however, from what
I understand about this, my ADMT should take care of resetting the
permissions on the mailboxes of the branch Exchange 5.5 server to reflect
the merged/migrated user accounts. We would love to also consolidate the
Exchange servers into one Exchange 2003 Server, however, I am concerned that
there will be bandwidth issues. I have read that Exchange 2003 has the
capability to do so with it's over-the-wire MAPI compression and client-side
caching, however, I really do not want to cause much delay to the end users
at the remote branch. Should I simply plan on having an Exchange 2003 server
at the remote site? Are there any guidelines available when dealing with
bandwidth issues, server consolidations from Exchange 5.5 multi-site to
Exchange 2003 single site via T1 connection? Any recommendations? What have
others experienced?

Thank you in advance,

Tony
