Hi, We are about to open a new branch and unfortunately their is no high speed Internet available until a few months. As a result we have had to connect to our ISP using 56K dialup...YUCK! I have our VPN Client (made with CMAK) installed on the branch server and successfully connects back to head office using this connection through Windows 2000 Server with ISA 2000. The VPN Client "Disconnect when Idle" is set to never, however we find that after about 30 - 45 minutes the dialup link disconnects. What could be causing this?
