We are in the process of changing our domain name so we will have to
change our DNS name that our GW clients use to talk to the server.
I know how to do it in the registry if the user is in online mode
HKLM\SOFTWARE\Novell\GroupWise\Client\5.0\DefaultI PAddress
HKCU\Software\Novell\GroupWise\Login Parameters\TCP/IP Address

But how can I push out the changes automatically for the users that are
in caching mode as GW in caching mode does not look at the above
registry entries?

Thanks in advance
