Thanks guys for the speedy response.
So I can only assume that if the option to leave the domain isn't there, then the CPPM probably isn't apart of the domain?
It is currently reporting that it is not apart of the domain.
Sorry if this seems strange. We had one admin that got a little ahead of us and said the CPPM had to be joined to our new AD domain before it was ready.
On a side note, if you have two CPPM servers in a cluster, do you have to join each CPPM server individually?
