Preparing Outlook Clients for Migration from Ex5.5 to Ex2003

Preparing Outlook Clients for Migration from Ex5.5 to Ex2003

In my environment the clients are running Outlook 2000 or 2002. The
current Exchange server is called "George" and there is a hosts file
on each workstation that points to this server. Because we are
running DHCP for workstation ip addresses, the hosts file should be
unneccessary, but that's the way things are at present.

I'm planning to migrate our mail system from Exchange 5.5 on George to
Exchange 2000 or 2003 on a server called "mailserver". To prepare for
this I have created a DNS entry for mailserver in our DHCP
configuration and pointed this to the George server. I can tell that
the workstations are using this entry because I can ping mailserver
from any workstation. My hope was that I could change the server
designation in Outlook on my 35 workstations ahead of the server
migration. Once the migration was complete I would then simply change
the DNS entry in DHCP and all the clients would find the new
mailserver.

Unfortunately, when I change the server designation in Outlook it only
appears to be changed. When I go back to check it is back to George
even though I set it to mailserver. How can I prepare the Outlook
clients for this migration? I don't mind touching each workstation
before the migration, but I'd like to avoid having to do it under the
time pressures associated with my users having no email while they
wait for me to convert their workstation.
