Hello,
after a complete reinstallation of a windows 2003 SBS server i get always a
error 733 (TCP/IP CP reported error 733: Your computer and the remove
computer could not agree on PPP control protocols), after I successfully
passed the authentification and the server asked for a callback.
I checked the following properties for vpn connection already:
-Client & Server are using the MS-CHAP v2 & MS-CHAP Protocol
-VPN-Type is PPTP-VPn on both sides
-The IP adresse is assigned from a static pool defined in RAS server
-My Router does not cause this problem, i still have it, when i try to
connect through local network with the ISA server not running
I have no more ideas what could cause the problem, but i would be grateful
for any hint to solve this problem.
Thanks,
Chris
