We have recently experienced constant disconnects on users' WS sessions. All PC users have a WS session file to connect to our AS/400. We have recently installed a ServGate M30 sercuity device/firewall. Aftewards, sessions constantly disconnect after periods of inactivity. All PCs are running XP pro, SP 2. All users are connected to our internal network. There are 2 users connected to our DMZ that do not experience this problem.
My troubleshooting has included the following:
1. A constant ping to the IP of the AS/400 shows no communication loss.
2. I created a KeepAliveTime DWORD in the registry (LocalMachine\CurrentControlSet\Services\TcpIp\Parameters\ and set it to 3600000 seconds (decimal)
3. I created a startup script at login - CWBCOPWR /KA:1 /MKA:60,3600
I have looked navigated through the ServGate device and do not see anything that would cause the disconnect because of inactivity.
Any help or suggestions is much appreciated.
