We have a basic windows network behind a Cisco ASA firewall/router. The Cisco runs into two Linksys gig switches which go out to the computers. There are only about 6 windows computers on the network. We were having problems with all the computers connecting to secure sites like Gmail and hotmail so we reconfigured the Cisco ASA from scratch and that problem has been fixed, everything else has stayed the same. Every since the router work windows file shares have been very unreliable. Sometimes they work, sometimes they dont, and it seems very random. When the shares do not work I get either a "System Error 53" or a "System Error 6118" when I run net view. During the file share problems I am still able to ping the gateway and get out to the internet. I can still resolve IP's of other machines but I am not able to ping them.
I have checked, and double checked to see if windows firewall was to blame, however, even with the windows firewall off the issues still persist. I have tried turning off windows XP auto disconnect feature and I have tried changing the Nics to run at 100mbps instead of auto detect.
attached is errors in command promt.
Any ideas what could be going on here?
