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 -----Original Message----- From: isapros-bounce@xxxxxxxxxxxxx [mailto:isapros-bounce@xxxxxxxxxxxxx] On Behalf Of Gerald G. Young Sent: dinsdag 12 juni 2007 15:56 To: isapros@xxxxxxxxxxxxx Subject: [isapros] Re: PPTP tracing 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.

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
