Hello

I see from the Microsoft website that the high ports that are needed are
random. I am looking for away to make it static as they FireWall policies
will not allow us to make a rule that opens all the high ports. (I was able
to do this for RDP using TCPIP Endpoints and assigning a static high port to
it)

Application protocol Protocol Ports
RPC TCP 135
Randomly allocated high TCP ports¹ TCP random port number between 1024 - 65535
random port number between 49152 - 65535²
NetBIOS Datagram Service UDP 138
NetBIOS Name Resolution UDP 137
NetBIOS Session Service TCP 139
SMB TCP 445

Have you read http://support.microsoft.com/kb/154596 ? It explains how to
restrict which ports are used for dynamic RPC.
