Windows cannot access \\servername from Windows Server 2008 R2

I recently set up a new Windows Server 2008 R2 64-bit machine in a network which is predominately XP and Server 2003.

  • After a reboot, \\servername works
  • A while later, \\servername -> "Windows cannot access \\servername"
  • \\192.168.1.xx works
  • \\servername.full.domain works

So, I've got work-arounds, but I'd still like to know why short-name resolution is failing.
