We have 2 Windows 2008 server dc's in 2 AD sites. When I ping the 2nd dc (from my pc)it resolves the address of dc1. I noticed this yesterday and in the dns mmc on dc1 I manually entered the correct ip address of dc2 in the forward lookup zone: _msdcs.domain.local, also have a host A record for dc2 in domain.local with the wrong IP (auto updated itself) this morning. Why is this occurring? Dcdiag has errors, (failed test Kccevent) and DS event log is full of 1311 and 1566 id's.
