Hi
Our company is planning to migrate to windows 20003 and
exchange 2003 from our existing Nt4.0 and exchange 5.5.We
are also replacing all old with new compaq dl 530.There is
almost 250 users and same mail boxs for all users. When we
are migrating we don't want to loose any mail, file
permission. Our existing network is like one PDC called
company_nt and BDC is for mail server(exch01) and there
are two more bdcs.One of my new server I install NT 4.0
and made it as a BDC then isolate from network upgrade to
promote to PDC,then upgrade it to first DC in the
forest.Now usres can login to new 2003 server with old
user name and password.I made a second DC and a member
server on new server we want member server is a mail
server. When am trying to connect to Exchange 5.5 using
ADC I am getting error that exchange name ,port or
permissin problem osccur while trying to connect to 5.5
(deffrent organisation name ). I create a two way trust
between the both server,still I am getting the problem.
Please advise me is any other way I can do my migration
with least configuration changes .
