On our domain 2003 server we having running our proxy server (Wingate). We were running all our Internet/Email and VPN through one internet router without problems until recently when we installed a second line and switched our Internet and Email traffic over to it.
Now user keep getting kicked off the internet with Sock 500 errors. Even stranger is that the new router will ping from every machine on the whole network apart from the Domain server, which of course is a problem. If the router is rebooted it will ping from the domain server for a short while and then stop.
We have tried replacing the router but the problem continues. If a user is directed to the internet directly through the router there is no problems. So the problem lies in either the domain server or the proxy server Wingate.
