Hi

i have a small windows server 2008 R2 Domain with Symantec Enterprise Protection Suit as an AV solution and Microsoft ISA Server 2006 as a firewall.
its been about 2 weeks that all clients are showing the yellow  "No Internet Access" sign on their connection icon in the system tray although they are connected.
Any idea why this is happening and how to resolve it?

Many thanks

have you tried disabling the protection suite temporarily on a test machine? or disabling ISA for a brief moment on a machine that has the protection suite enabled. is probably one of the two. I know the troubleshooting sounds a bit haphazard or dangerous but it depends what you have inside the LAN as to how it would affect you momentarily to help decipher the cause.
