Simple network. One Server and two clients. For a year the network was great. File shares operated perfectly. Last Tuesday windows automatically downloaded and installed security updates and the network connectivity went down.
I have discovered that if the firewalls are turned off the mapped drives will connect. When the firewalls are turned back on the mapped drives drop and communication goes bye bye. I have tried so many things. Adding new rules, opening ports
and still the network will fail when the firewalls are turned back on. If anyone has any suggestions I need help. The OS on the server is Windows Server 2008, the clients are running Windows 7 professional. The only other software on the
pc's is AVG business security edition. Any suggestions are appreciated. Thank You.
