I'm having AD issues running VMWare. I have 64bit Windows 2003 Enterprise running as the host OS. I have multiple VM machines that are running Win2k3 Standard edition. Everything was working fine with the VM Machines until I created a new site and made the host OS a Domain Controller. The IP addresses for the host and guests are all on 192.168.5.x network with same subnet mask. DNS and AD appear to be working correctly between the two sites. However, the VM machines now cannot authenticate to this DC since I changed their IPs so they would be in this new AD site with the host DC. I have no problems throwing a standalone workstation on that subnet and joining the domain and having the workstation authenticate to this DC on this new AD site, but I'm having problems with the VM Machines. VMware is setup so that the phyical NIC is bridged. Any suggestions?
