VPN issue - LCP: timeout sending Config-Requests

I have been having issues with my VPN connection on my server. If I try to connect to it I get the following error:

2010-12-08 18:29:49 EST --> Client with address = 192.168.0.XXX has hungup

Can somebody please provide me with some insight into the reason why this would be happening?

Thanks

I am having the exact same issue. On my end the problem is with Windows 7 clients who receive this log on the VPN server side. If you find a solution please post. I am using 10.6.4.

VPN has been a continuing issue in or organisation. There could be more than one issue problem causing the issues we have, however we have found that our Netgear router appears to have issues. After a bit of research on other forums I found other people who had flagged other Netgear routers as having similar issues and that VPN connections could be reestablished buy turning on and off settings with in the control panel for the router. Doing so jogs it working again for no apparent reason, even when the resulting settings are exactly the same as before.

It is because of this reason and other issues I have had with other Netgear routers that I have decided that I cant fully fix our issues with VPN until we have replaced our router with something more suitable.

I don't know if it's a router issue. We used to use a Netgear router and the VPN worked better than with the new Cisco router. I'll play around with the Cisco router and see if that helps.
Mac users have no problem connecting to the VPN, just windows 7 users.

Problem solved. It was not a router issue for us.

It was the setup on the PC side. It only will connect via PPTP so we are using that and turned off L2TP.

under Options/PPP I have only Enable LCP extensions checked.
Security tab Challenge Handshake checked and MS CHAP Version 2 checked. Require encryption(disconnect if server declines).
Networking/Advanced TCP/IP checked Use default gateway on remote network
WINS/ Enable NetBios over TCP/IP is circled.

That's pretty much it on the client side.
