I have 2 FBSD workstations that should have been configured the same.  
However, one has problems with NFS mounts, the other does not.  Except 
for hardware and vn option enabled on pserver, kernels configuration 
files are the same. 

Problem child is pserver.

bash# uname -a
FreeBSD pserver 2.2.7-RELEASE FreeBSD 2.2.7-RELEASE #0: Tue Jan  5 13:48:28 EST 1999     root@pserver1:/usr/src/sys/compile/PSERVER  i386
bash# mount akin:/u7 /mnt
bash# ls /mnt
ls: mnt: Permission denied

Running snoop on akin;

# snoop -o snoop.out pserver aliskingsport
Using device /dev/hme (promiscuous mode)
12 ^C
# snoop -i snoop.out
  1   0.00000 pserver -> aliskingsport PORTMAP C GETPORT prog=100003 (NFS) vers=3 proto=UDP
  2   0.00085 aliskingsport -> pserver PORTMAP R GETPORT port=2049

 12   0.00015 aliskingsport -> pserver RPC R (#11) XID=726953992 Can't authenticate (too weak)

Antares works as expected;

root@antares# uname -a
FreeBSD antares 2.2.7-RELEASE FreeBSD 2.2.7-RELEASE #0: Wed Feb 10 13:27:30 EST 1999     root@antares:/usr/src/sys/compile/ANTARES  i386
root@antares# mount akin:/u7 /mnt
root@antares# ls /mnt  ... listing follows as expected

Running snoop on akin;

Any help is appreciated.  Happy to provide any additional info.
