We are running GW 8.2 on a Windows 2008 r2 2 node cluster. These servers reside in a Windows 2000 domain. We are upgrading to a 2008 domain. I know we have to completely rebuild the cluster. How will that affect GroupWise, if at all. Also the new domain will have a different name since there is no upgrade path from the 2000 domain to 2008. This only affects the servers running the po's, and mta. GWIA and WebAccess are in a separate domain that will not be affected.
