I was able to add a workstation into the PVM configuration from the
Paragon. A few users have been telling me for some time that the Paragon
bug had been fixed. Our site uses pexec and I have not figured out how
to run pexec using rsh from my workstation.

If your site doesn't use pexec, you might try adding the Paragon from
another host. Please let me know if you still have problems.
