4     Subject: [PATCH 1/2] rpc_server: Use the RPC TCPIP ports of Windows
5    
6     Since Windows Server 2008 Microsoft uses a different port range for RPC
7     services. Before it was 1024-65535 and they changed it to 49152-65535.
8    
9     We should use the same range as these are the ports the firewall in AD
10     networks normally allow.
