Is the problem possibly hardware specific? What kind of hardware are you using? I'm just curious if you've tested it on multiple systems. Good find.

Please excuse if this has been posted before, I did a quick search of the archives and found nothing This hasn't been sent to MS, as I don't know an email address to send it to, Aleph, if you find it worthy of sending, please forward a copy to the MS people for their attention. Cheers. I was playing around with PPTP last night, and discovered that, with "very" minimal effort, I could cause my friends NT Server (version 4, service pack 4) to reboot instantly, without shutting down. All I did was telnet to the port (1723) on the NT box, and then send the following data. hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

hhhhhhhhhhhhhhhhhhhhhhhhhhhh (that's 256 'h's for those who don't want to count:-) and hit return. nothing. BUT, then I hit ^D and all hell broke loose. The NT server dropped like a stone, full hardware reboot. I tested this multiple times and always got the same response. The NT Server was version 4, with Service pack 4 applied. Cheers Simon
