Cannot ping Win 7 from other connected computers
Hi, I am new to this forum, this is my first post.
I have setup a test LAN with 4 computers, 3 running different versions of Ubuntu and one running Windows 7 Ultimate 32 bit. Until three days ago I did not have a problem pinging between any of the computers. My project is build one of the Ubuntu boxes to be the gateway/router/firewall/VPN server for the LAN.
On Thursday I suddenly could not ping the Win 7 box from any of the Ubuntu boxes. The Win 7 box can ping any of the Ubuntu boxes. But what is even worse, I no longer am able to connect via Putty from the Win 7 box to any of the Ubuntu boxes.
I have disconnected the LAN from internet access and turned off the firewall on each of the boxes. I have checked all network settings. I have searched the internet for an answer. All without success.
The only clue I have to the cause of the problem is that on Wednesday night Windows 7 performed an automatic update. In my focus on building the gateway/router/firewall/VPN server I failed to do two critical things on the Win 7 box. Turn off automatic updates and create recovery points.
Does anyone have an ideas on how I can correct the ping and Putty problems short of reinstalling Win 7?
Thanks,
