VPN client constantly disconnects on Windows 2000 Server

I have a Windows 2003 Server that is running the VPN client that connects back to a VPN terminated on a Pix Firewall. The connection on this will only stay up for about 5 minutes at most. I can take an XP machine and connect even via wireless on the same network and never have the connection die. I have tried different ports, port negotiation, etc. I have gone through several versions of the client hoping that the next release will work better but I have always had the same issue with the Client disconnecting on this system. Anyboy else every see this or have some ideas of what I can do?

Re: VPN client constantly disconnects on Windows 2000 Server

Check in VPN Clients with the keepalives and the response timeout setup:

Try to set some keepalives on the client machines. To do this you need to go to the VPN Client machine :

Start/programs/ciscovpnclients/vpndialer/options/properties/ and set the peer response timeout to 480.

Also try to set up the keepalive for the vpn client machine as well. You need to do the

following: Look for files: .pcf

if ForceKeepAlives=0 Please change it to ForceKeepAlives=1

Check in PIX lifetime of the isakmp policy and idle-time for the vpn clients:


isakmp policy 10 lifetime 86400

vpngroup counsvpn idle-time 7200
