We have successfully migrated Exchange 2000 to Exchange 2003 on a new dell server in our two server domain. Now, I need to uninstall Exchange 2000 from our Windows 2000 server. When I went to uninstall, it said that this server cannot be uninstalled because it is a member of the routing group. Please make some other server a master router in order to uninstall. I am not sure what to do? i do see both the servers under the Routing and messaging group. All excahnge services are turned off on the old server but still this error please advice?
