We're experiencing this issue as well with our network. However, we have a mixed W2003 and W2K server AD environment.

Both of other W2K servers are pretty much defunct now. Hopefully sometime tonight or tomorrow, we're going to demote them both to test this W2K theory out. Ideally, we want to introduce our Windows 2008 servers into the AD domain, but can't do so until we raise the forest level.
