I have an Exchange 2k3 str Win2k3 member server in a Win2k Active Directory. After I demoted one of my DC and doing some DNS changes, mail seems to drag. On occasion, when a users view a message the “requesting data” box pops up. Or messages will hang in the out box. I’ve ran “Replmon” and have found an error related to deleting a server not being successful do to DSA and DNS lookup. I also notice that messages drag in the local delivery Queue, in inbound and internal.
