Could you provide a bit more info on your setup? How are you accessing the web, via a router, proxy server etc.? Is this from home, or at work?

I'm connecting from a cisco router to one of the server nic cards.  I use the server as a firewall. 2 nic cards. The network connecting through this server access the internet without a problem, so I have eliminated the router as a problem.  I see no problem with communication with either of the two nic cards in the server.  I'm using IE7.

Soo your saying that the server is one which cannot access the web, but the network machine's can?

Are you using a proxy server?

Have you just upgraded to IE7? did it work with IE6? How long have you had this issue? Have you installed any service packs or patches?

I guess my machine is the proxy server. It is plugged directly into the router, and provides internet and print functions for the rest of the company. I noticed the problem a few days ago when attempting to download new virus definitions.  I am current with all patches,and some were recently installed, so that might be a possiblity, but the ability to pull down email and run vpn sessions, but not got to a web address on the same server really confuses me.

So you are trying to browse from your server machine? It has two network cards? How have you configured them? One is external and connected to the router? The other one is internal and connects to a switch with all your internal client machines?

Yes the cards are set up that way, and it can download email, and connect via vpn, but can not browse

Is there any proxy settings that you enter on the clients for them to browse the internet?

I manually put in dns addresses into clients, but run dhcp off the server.

As I was trying to download anitvirus files to update due to the lack of connectivity. AVG had a posting about lost connectivity from the last update.  The last automatice update "broke" connectivity.  THey had a fix, and it worked like a charm.

Thanks for the try.
