Am I correct that each "DC" is the instance of Win2K8 running AD/DHCP?
It appears they have multiple NICs on the same subnet with differing IP's and have NetBIOS enabled? -sc From: Sean Rector [mailto:[email protected]] Sent: Wednesday, September 02, 2009 8:15 AM To: NT System Admin Issues Subject: NetBT errors... Pair of HP ProLiant DL380G6 servers with dual Quad Xeon Nehalem processors & 32GB of RAM. These servers host my VMs and are my DC's as well as 50/50 split DHCP servers (65 workstations). I'm getting a ton of NetBT errors - ID 4319. Only thing is, I can't find an IP address in conflict. I have two physical adapters for each VM (under Hyper-V) as I have the VMs clustered. The VM's physical adapters get their IP's from DHCP, and the virtual adapters within the VMs have static IP's. Let me know if you need any further info... Thanks for your help!
