Windows 2003 phantom duplicate IP and unable to login to the domain

Hey everyone,

I have a weird situation that I have never seen before.

I have a server (virtual on ESX) that is a windows 2003 R2 enterprise box.  For some reason I am getting IP Address  conflicts and presented with the error below:

Windows - System error

There is an IP address conflict with another system on the network.

What's weird is that nothing else is assigned that IP address.  When I shut down the box, I can no longer ping it.  I changed the IP address of the box and the error went away.

However, regardless of what IP Address I use, I cannot log onto the domain and I get the following error:

Windows cannot connect to the domain, either because the domain controller is down or otherwise unavailable, or because your computer account was not found.  Please try again later.  If this message continues to appear, contact your system administrator for assistance.

I can ping the domain controller and have verified that the computer is listed in the domain through AD Users & Computers.

Does anyone have any ideas what could be causing this?

    It looks like for some reson your pc has lost its connection to the domain, the easiest thing to do would be to delete the pc account in ads and remove and re add the pc to the domain.
    Im not really sure what could of been causing the ip problems though!

    I figured out what the problem was.  Someone turned on the old VMWare box, that had the pre-migration servers.  It caused all kinds of havoc.  Thanks for the input.
