i followed some of the infomation here to resolve some replication issues,
i specifically did this,
Imran Hashim (Last update 5/9/2005):
This event sometime occurs in an environment with large number of sites and domain controllers when connectivity to one or more sites is lost. ISTG tries to reach that site through alternate routes available and creates new connections for this purpose. By design in Windows 2003, these connections should be deleted automatically when original connectivity is restored, but in Windows 2000 these links are not deleted. You have to go to NTDS Settings of all the servers in affected site and delete all connections, and initiate "Check Replication Topology". ISTG will create all the links from scratch for all of these servers and problem will disappear.
but now i cannot get anything working on this DC. DNS stopped running, i cannot get back into sites and services and i am getting a bunch of errors.
is there something i can do to revert back?
