Question : Cisco VPN Client 5.0.05.0280 disconnects after about 10 minutes

Cisco VPN Client 5.0.05.0280 disconnects after about 10 minutes.
I've removed all other unused network connections (like wireless) and still have this problem.
Running on Windows XP SP3, Windows firewall: OFF, McAfee firewall: OFF.
Any ideas?
Below is the VPN Client log portion where it disconnects:
