Could anyone please help. I had one Win2k3 DC on my site. I added another win2k3 server and later promoted it to a DC using DC promo. Then i demoted the old DC using dcpromo. Now the event log of my new DC fills up with a recurring DNS errors 4015. This is then followed by DNS errors 4513 and 4514. The server wont replicate with the other in the domain. I use single domain with multiple sites. I am new to Active Directory, DNS,etc. Does anyone have an idea of what could have gone wrong and how to solve my problem.
