I'm not sure if this is a problem with WinGate, my Intel ethernet devices the motherboard or Windows but I'll post it here anyway.
Every now and then (maybe twice a week) all LAN clients lose connectivity and the usual "limited connectivity" exclamation mark is displayed over the network icon in the notification area. The server can still connect to internet, and everything seems peachy with ipconfig.
If I reboot the Wingate server, everything is fine again. The wonky thing is if I try to disable and re-enable the local network adapter, it won't turn grey. If I try again a few times, it does turn grey, but then won't turn on again. If I now try to reboot the Wingate server it will be stuck at "Restarting ..." and I need to hit the reset button.
