I want to think this is a firewall issue with an 08 server. Its roles on the network are DC/DNS/FPS.
Approxamatly once a day, users are no longer able to connect to thei fileshares on the server. All other services remaining function DC replication/ DNS etc etc. I can ping, and 3389 over to it.
Start/stopping the firewall does nothing... if I reboot the server the problem goes away. There are no errors any of the logs.
Any help appreciated.
