Logging onto a MS Server 2003 domain?

I cloned my PC and was able to log into our MS Server 2003 domain at work.

But about 2 hours ago, Windows stopped allowing it during boot up and says:

"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."

The original PC still allows me to log into the domain at work, so there is nothing wrong with the MS Server 2003 side.

I figure somehow Parallels no longer is allowing a pass through to share the network, but I still have it set up to share.

Any ideas?
