With the most likely problem apparently out of the way, let's look at
the second: when you access the NFS export, three daemons get started
(mountd, nfsd and portmap) under their own account (apparently .\nfs?).
Those should see the following mount points according to cygcheck3.out:

C:\cygwin        /          system  binary,auto
C:\cygwin\bin    /usr/bin   system  binary,auto
C:\cygwin\lib    /usr/lib   system  binary,auto
cygdrive prefix  /cygdrive  user    binary,auto

and since they appear to be working correctly (but check the logfiles)
one can assume that these mounts are present.

When you run bash before starting the daemons you said you see these
mounts instead:

C:/cygwin/bin on /usr/bin type ntfs (binary,user)
C:/cygwin/lib on /usr/lib type ntfs (binary,user)
C:/cygwin on / type ntfs (binary,auto)
C: on /cygdrive/c type ntfs (binary,posix=0,user,noumount,auto)
D: on /cygdrive/d type ntfs (binary,posix=0,user,noumount,auto)

So there must be an fstab entry that changes /usr/bin and /usr/lib to
user mounts.  What happens if you get rid of those two entries, either
in /etc/fstab or /etc/fstab.d/<user>?


Regards,
Achim.
