I set a new client Friday with two new Windows 7 pro stations connected to a single switch. They are both domain members but share files from station1 (one of the new machines). I had a mapped drive from station 2 to station 1, etc and it all worked fine. Now today station 2 cannot access station 1. It cannot ping it, rdp to it, etc but it can access all other network stations. Station 1 can RDP to station 2 but cannot ping it probably because its firewall is on. I then disabled firewalls on both stations and have the same issue. What could be happening with this? Maybe there was a bad update.
