You may be disconnected from the domain controller and the user that is able to log in has logged into that machine before and is using cached domain credentials.  To test this see if another user who has never logged into this machine can log in.

I would perform the above test and also some basic network diagnostics (ping, etc.). For the latter you can use one of the "successful" accounts on that computer.

Boot it up in safe mode and re-enable the local Administrator account.

Do-not-ever disable it again, assign it a crazy password, write it down on a note and lock it away if something like this happends again.

Also, don't virtualize all your basic networking services (like a domain controller). Install windows server on a old PC, configure it as a domain controller, global catalog, DNS and DHCP (if you use DHCP), and place the PC somewhere else in the building.

Cheers..!!

I'm fairly sure I should receive credit for this answer.  Not my fault the one who posted the question never responded.  I'm a Director of IT of a software company and I'm familiar with Domain Controller interaction.
