Hi, Well we sorted out our domain issues - it was all due to the Broadcom network bonding/teaming software we use from Dell. Removing the software and using one NIC worked like a charm, and we now have 2 W2k8 domain controllers up and working very well. Will probably go native with W2k8 tomorrow or Monday. That lead me onto another question that I have with my Vmware installs. Does Vmware allow you to do network bonding, or is this even a recommended configuration? I am asking because I can see a requirement to have the management port and the server ports on two different network cards (though they can of course share the same interface if you wanted), but I just wanted to know if it did bonding at all of interfaces? We bond across switches, but just use the standard host-based bonding, where if one card can't communicate, the system tries through the other card. Thanks.
