Restrict Port-Range DCOM

SpugnaJun 7 2011 — edited Jun 7 2011

Hi,

I have to configure HFM (9.3) and dcom for use it through firewall.
If I have understood, I should open the port 135 for RPC.
Usually I should open a wide range of ports:

1024 - 65535 for windows before 2008
or
49152 - 65535 for windows 2008

because this is the port-range that dcom process will use, choosing randomly one from this.

I can restrict this range how it's described in the kb
http://support.microsoft.com/kb/300083
or
http://support.microsoft.com/kb/154596

then I have 2 questions.

1) This is the right way to solve the problem?
2) If I have to restrict the range, what is an acceptable range? 100 ports? 1000 ports?
should I use a formula to calculate the minimum or maximum number of ports?

thanks in advance.

Danilo
