SUMMARY
If you use Network Monitor in Systems Management Server version 1.2 or Network Monitor from the Windows NT Server version 4.0 compact disc, you will not be able to view Point-to-Point Tunneling Protocol (PPTP) or General Routing Encapsulation (GRE) packets. At the time these products were released, it was not known what port would be used for PPTP.



MORE INFORMATION
To view PPTP and GRE packets, follow these steps:  In the parsers directory created by Network Monitor, edit the Tcpip.ini file. In this file, find the [TCP_HandoffSet] section. At the bottom of this section, find:

5678 = PPTP

 Change 5678 to 1723. Save the file.

When you run Network Monitor, you will now see PPTP session packets, and GRE packets initiated by PPTP.
