Re: [ActiveDir] There must be an easier way...
Hello Larry, Unfortunately there is no way around doing a metadata cleanup against those 2 DCs that have been removed from your domain and are not going to come back. You would want to figure out the machines in that particular subnet where the 2 DCs were, have connectivity to an existing and functional DC to be able to logon to the domain. Also, from your description, it seems that atleast 1 DC which is giving the error, is part of that domain from which the 2 DCs were yanked off. If there are more DCs, and are set to replicate with either of the 2, they will also give replication errors unless a metadata has been performed.

RE: [ActiveDir] There must be an easier way...
Brian, I never did this, but I guess I should try it if one domain tree established the forest, another domain tree is added, but then the initial tree is removed won't that cause problems for the other domain tree, even if they clean up the forest and seize the FSMO roles. The schema and configuration containers will reflect the naming context of the root forest. Also that is where the enterprise roles will exist. I think the only thing the non-root can do is reinstall the Forest, while the forest root can just do the clean-up.
