No, but on the AD DC.

I was talking about the *client* options.  For XP all I said can be
ignored, except the provider order.  On XP you can simply use a passwd
and group file (NOT the Cygwin passwd and group files!) for identity
mapping on the client machine.

SFU *is* the NFS client.  You seem to expect that there's some user
space executable which constitutes the NFS client, but that's not the
case.  The OS driver *is* the NFS client.  Full stop.
