Hi ..I am facing a sever problem in internet connectivity on few computers in the LAB. They are connected to domain but don't connect with internet. Shut down and restart resolves the issue but sometimes this trick doesn't work.
I can ping the server and gateway but can not ping the website and this issue occurs on random computers. There is proxy settings but they are correct.
Can anyone help me with that. I am in serious trouble. Don't understand why is this happening.
I had many many issues when I was changing over from IE7 to IE8 we use proxy.pac (FQDN config script) and wpad.dat in our DNS/DHCP. Automatic configuration failed randomly for some clients - no reason at all. I spent many days fault finding custom install folders in IE, DNS, DHCP. In the end I decided IE8 was crap, however, the proxy configuration script via FQDN always worked. so a few GPOs later and I was good to go.
Check your GPOs, strip them down and have ONE that deals with IE configuration (per logon path that is, obviously one per forest would be unworkable for most people! but make sure each person only has one possible IE configuration GPO in their "path")
