the user group is a system group (read: installed by default USUALLY depending
on the system).  It is also generally not exported by the NIS group map (unless
you edited /var/yp/Makefile, which I get a feeling you did not).  To verify
this, try 'ypcat group | grep user' on one of your NIS clients.  Then try 'grep
user /etc/group'.  If I have read your mind correctly so far (not knowing what
OS the NIS server is running nor any of the clients),  you should notice that
the client which displays GID 100 doesn't have  the user group in /etc/group.  
Adding it will make that pesky 100 change to user.
