Hi Jim, I like very much Wireshark or NetMon, but it's not always convenient or even possible to install that thing on a users pc to diagnose VPN connection problems through sharing/NAT devices. Nevertheless we have to prove that those sharing/NAT devices or the culprit. Therefore the call for another method to collect some hard evidence ;-) BTW --- why isn't there an SSL/TLS parser in Netmon 3.1?

NetMon3 parses PPTP quite nicely. -----Original Message----- From: isapros-bounce@xxxxxxxxxxxxx [mailto:isapros-bounce@xxxxxxxxxxxxx] On Behalf Of Stefaan Pouseele Sent: Tuesday, June 12, 2007 6:36 AM To: isapros@xxxxxxxxxxxxx Subject: [isapros] PPTP tracing Hi, Is there any way to trace the PPTP negotiation itself, particular the Call ID negotiation, without using a Network Monitor on Windows XP, 2003 and Vista? I've looked at the "netsh ras set tracing Component enabled" command, but it's unclear which component should be enabled or if it is possible at all.
