Hi all, We do need to move an exchange server physically ( mean to put it in a car an take it back to headquarter ) during we and need it to work for Monday. It's Exchange 5.5 SP2 on Windows NT4 SP4. This server is the only one in the Exchange Site. It will remain in the same NT domain. Replication with Intersite Connector between sites. X400 and IMC on it. As we are going to change it's IP because it will be on another subnet. Any slide effects ? As far as I can see, we only need : - change IP entry in WINS to ensure new name resolution for clients and Intersite Replication - change external X400 systems to point to this new IP - change IP on the mail relay to send to this new one Regards.
