I have a small app server that I have recently lost the ability to connect to my clients. I have tried using windows explorer, remote desktop, vnc viewer, PSExec, various other pstools, all with no luck. The only connection that works is the other machines on the same vlan. This did work before yesterday however, and nothing has changed in network infrastructure, no firewall rules have changed, and the other servers from the same VLAN and switch can talk outside their VLAN. I installed Spybot as a precautionary measure and I believe TeaTimer is having a problem, but I don't know how to un-immunize(if that's a word) and I've even tried uninstalling and reinstalling TeaTimer, to no avail. This is my WSUS server, please help!!!
