One of the techs here removed one of our exchange servers from system manager by right clicking and deleting it thinking he could add it back. Well that stopped it from working.
I have tried running forestprep and domainprep. I also tried to run the setup again thinking it would fix the problem but it asks for a exchange 5.5 server and we do not have any of those around and I am assuming that is because it looks to active directory for the server name and can not find it.
How can I fix this?
