Assuming you have an equivalent server to move to that is the cleanest "fix". Of course this assumes that the server tanking was caused by having both AD and Exchange on the same server. Although having Exchange and AD on the same server is not ideal it is a supported configuration. Do you have any additional domain controllers already or is this the only one? I assumed based on your statement of moving FSMO roles that this was your only domain controller. If it is, my first priority would be to create an additional domain controller. The current server is overkill for this role and unless the collocation of Exchange and AD is directly related to your sever having trouble it seems like adding the additional disruptions of moving all the mailboxes would not be warranted.

Either to promote or demote.

I want to know what's the best plan of attack to swing either AD or Exchange 2003 because yesterday the server tanked, I was able to get back up and stable again, however I think its probably I good ideal to separate the AD from Exchange so don't run into problems again. Someone suggested to me that I created a new AD and replicate it with the existing one, once its fully replicated and everything is working to snuff move over the fsmo roles and demote the AD on the eXchange. I am wondering what else I am going to need to do after that's done so that Exchange doesn't whipe out. Regards, Andrew
