[Gary Ren]

Hi Brian,

Many thanks for your email.  I tried "exec /sbin/sh". It does not work for 
root. Anyway I have power off the workstation. By the way, could you please 
tell me how to creat a root2 which have same right with root. With group 
and which UserID should I use.

I appreciate a lot.
