Well Jim I finally got it cracked. I have always known how to restrict the
port range in DCOM
which I did (I used Ports 5000-5025) and opened up TCP Ports 5000-5025 on my
access rules
accordingly. The thing I was missing to get it all to work was to uncheck
the option "Enforce
Strict RPC Compliance". This was mentioned in the Beta 2 release notes.

Thnaks for all your help.
