Thanks Tom!
I will continue to look for a KB that will help. (what does IIRC mean?)
Clients are all XP pro and one 2k Pro using Outlook 2002 (updated and patched).
Neither ISA shows anything in the System / Application event logs ...... except
for a crap load of :15105 notices
"ISA Server detected an all port scan attack from Internet Protocol (IP)
address x.x.x.x"
Should I be doing something with these source IP addresses?

Hi Joseph,
It could be the client operating systems. I recall a KB article that mentioned
a fix for PPTP connections that dropped early -- but IIRC, the drops took place
after a minute or two.
What client OS's are they using?
The Event Viewer on the VPN server usually says why the connection was dropped,
if the VPN server was aware of the droppage.

Subject: VPN Clients - No PPTP traffic
I am at a remote site - inwhich which all users connect to the main
office via individual VPN clients (temp situation for next 2 months). After
approx 20 minutes, no traffic seems to go through the PPTP tunnel.
If I disconnect, then re-connect all works well. I don't know if one of
the ISA boxes are to blame.
My laptop is also connected to the main office, with the same
applications opened and I have no problems.
Main Office Firewall: Windows 2003, ISA 2004.
Remote Office Firewall: Windows 2003, ISA 2000.
Help! Please Help!
