Hi Gerald,
I'm just looking for another method but a NetMon trace to easily collect some
hard evidence that some sharing/NAT devices breaks PPTP VPN connections.
Therefore we have to analyze the PPTP negotiation itself and in particular
check out if those sharing/NAT devices properly handle the CALL ID's. In fact,
a similar method as the Oakley log for L2TP/IPSec would be great.
BTW --- Google doesn't give the answer I'm looking for ;-)
Thanks,
Stefaan

I assumed you were having issues with connectivity and asking for ways to
troubleshoot them.
What is your objective here? To troubleshoot an issue? Or are you simply
asking a yes or no question (i.e., is it possible to trace a pptp negotiation,
exposing the call id negotiation natively in Windows using netsh)?
If the latter, my guess would be no, but then I'm not sitting in front of a
server running RRAS. Try using netsh ras show tracing for a list of components
and see if anything related to PPTP is listed.
Otherwise, I'm thinking a Google (Ahem, Desktop Live) search is probably
justified.

Gerald,
I do *not* want the PPP trace but the PPTP trace! The PPTP stuff itself is
happening *before* the PPP negotiation starts ;-)
Best Regards,
Stefaan

Stefaan,
Try the catchall version of that command:
netsh ras set tracing * enable
Then run your test again. Once complete - and assuming the problem was
experienced, disable tracing:
netsh ras set tracing * disable
Take a look at the log files in %windir%\tracing.
You may need to engage the MS RRAS team to further determine any underlying
cause of your problem. Based on current posts to
microsoft.public.windows.vista.networking_sharing, they seem a pretty active
bunch.
Specifically, though, I believe the component you're looking for is just ppp.
netsh ras set tracing ppp enable/disable
After tracing ppp, you should see a ppp.log file in the above mentioned
directory.

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.
Thanks,
Stefaan
