Here's a thought....
Maybe the culprit on these boxes is the modem or modem driver. I had the
client remove the entire network stack including LAN and modem drivers,
run regclean and then re-install the whole shooting match because of one
symptom dhe reported: after making a PPTP connection, none of his
DUN functions worked until he rebooted the computer.
I'll let everyone know what the outcome is.
I will also submit some detailed "Win 9x client" instructions once I get
the documnet finalized and stress tested. Perhaps if several people
contribute a version of these instrctions we can narrow down what works
and what doesn't into a "Win 9x PPTP How-To" or some such idea.
In the near future I'll also be working on getting the users who use AOL
for their connectivity connected via the tunnel...this oughta really suck
;)
