I have a couple of Win2k pro machines that have lost access to the domain. I am running all NT40 SP6a Servers. After logging on to the Win2K Pro system locally the system reconfigures itseld for workgroup access and I can no longer access the domain. I have tried removing and recreating the machine account. I changed the SID. I don’t know what else to try. The only way I have been able to get these systems back on the Domain is to reinstall from scratch.
