I could be wrong but I thought I saw an announcement on this come across
the NTBUGTRAQ mailing list.  I thought there was a patch to either
WinNT/2k or WinXP to allow the interoperation.  I'll look through the
knowledge base and see if I come up with anything but I'm not certain
I'm remembering correctly.
