I think the 2K3 DC you're using is blocking authentication against
IPC$ but permitting GUEST which is a little strange from a logical
standpoint. I suspect it's a non-standard config as I believe there
are a lot of people using the filter against 2K3 DCs. There are some
workarounds that jcifs can do (e.g. jcifs.smb.client.logonShare) but
you might ask your domain admin about it as it could be a mistake. He
might have goofed editing the permissions on IPC$ or something.
