Here is the situation.
We have a customer that has a 2003 server standard backup domain controller running Exchange 2003 that has problems with Exchange services starting.
When trying to browse DNS manager we can connect to the primary domain controller from the bdc but cannot connect to the install of DNS on the domain controller that has Exchange installed. This was setup before I got involved and obviously according to Microsoft a domain controller should never have had Exchange installed on it.
We were thinking that theoretically since the other domain controller is working that we could demote this domain controller to a member server and Exchange should still work.
Anyone had experience with this or any suggestions on how we should proceed?
