Invalid fs type <NFS>

[Ellis Carter]

I am having a problem installing NFS on ISC 2.21.  TCP is working fine and I
want to mount a file system from another box running ISC 2.0.2.   I should say 
that NFS installed ok, and initialized ok.  I got all the correct responses that
the manual says that I should have.  This only happens when I try to mount a
remote file system.  Other clients can access these file systems, but they are
currently running under 2.0.2.  I have in my fstab file the following command:

epca:/u /epca/u NFS,soft,rsize=4096,wsize=4096
 
I need the rsize & wsize (4096) entries because I have a 3COM card and the 
release notes say that I cannot use 8k buffers with this card.
When this filesystem is mounted, I get the errormessage "Invalid fs type <NFS>".
I have tried to mount it manually and I cannot get past this error.  
The /etc/exports file on the host has this machine listed for exporting.  I am
trying to move from 2.0.2 to 2.2 and am not having much success.  Any help or
direction can be directed to ellis at epca.wpg.com.  All help/direction is 
appreciated.
