Changing the IP Address of a Host

Before changing the IP address of a domain, back up your IMail registry.

To change the host IP address:

1. If you have not done so, bind the new IP address to the NIC (network interface card).
   • Navigate to Control Panel/Network Connections/LAN or High Speed Internet Connection.
   • Right-click on the Connection icon and select Properties. Scroll through the list under This Connection Uses the following items to (Internet Protocol ) TCP /IP. Click the Properties button.
   • The General tab appears. Enter the new IP address in the appropriate text box.
2. Run Regedit and locate the following key:

   HKEY_LOCAL_MACHINE/Software/Ipswitch/IMail/Domains

3. If you see keys for both the old and the new IP addresses, delete the old one. First, make sure that the "Official" value under the new IP address key shows the correct host name. If you only see a key for the old IP address you can rename that key to the new IP address.
4. Highlight the host name key associated with that IP address, and make sure its "address" value is set to the correct (new) IP address for that host. If it is not, then change it.
5. Stop and restart all services.
