Hi Bob,
unfortunately the DCs are VMs, which is why none of the users can connect with their credentials. None of the PCs are getting IP addresses so naturally the DHCP is on one of those virtual DCs. I don't know the vcenter nor the ESX root passwords. Everything here was extremely well planned for disaster events - all IP addresses and credentials are stored on the network which I naturally can't access. I do know the ESX ip addresses though.
You have any ideas?
Cheers,
Luke
