Frequent disconnects with NC running Vista, IE7 and NC 6.5r1

I am getting a lot of users who are frequently disconnected while using Network Connect. Not everyone is experiencing the issues though.

We have an SA6500 and mainly use Network Connect. When looking at the users logs, I see a lot of the following:

Info
JAV20023

id=firewall time="2010-02-16 12:21:46" pri=6 fw=147.179.49.30 vpn=ive user=n0063518 realm="Vista_PROD" roles="Personal Markets, Hosting Services, Vista_Network_Connection, Global_Web_Pages, New User" proto= src=75.68.143.193 dst= dstname=TUN-VPN type=vpn op= arg="" result= sent=1758746 rcvd=1136808 agent="" duration=3605 msg="JAV20023: Closed connection to TUN-VPN port 443 after 3605 seconds, with 1136808 bytes read (in 4353 chunks) and 1758746 bytes written (in 3947 chunks)"

in some cases the users get disconnected every 3600(ish seconds), in others it is fairly random.

We have users with normal home network setups...cable modem, netgear or linksys router...some with vonage.

Any help would be appreciated

you will want to get the nc.windows.app error number these users get when they get dissconnected. most of the Dissconnect information is found in user logs rather than IVE

What is your session timeout? Idle timeout?

Are you seeing successful key exchanges (if using ESP)?

Do you see any other messages around the failure time?

Do you have Host Checker or Cache Cleaner that are running every 60 minutes?

Does this happen for your XP/7 users or only Vista?

This was a couple of issues. We were not doing any split tunneling and the dhcp lease on old routers was set to expire every hour. Since we did not do the split tunneling, all traffic was sent down the tunnel and the lease could not be renewed. The tunnel would eventually drop, then the lease could be renewed and finally the network connect session automatically reconnected. To solve it we simply allowed access to the local subnet (not preferred from a security standpoint, but solved the issue).

The second set of disconnects seems to be resolved with reinstalling the software.
