Are you accessing the internet thru the server?
Post the results of a ipconfig /all from the workstation accessing the internet

"The internet is going thru the server."

If there is no proxy then the internet does not go through the server. The internet goes through the gateway unless you are referring to the DNS which may be on the server. We need to see what the IPCONFIG /ALL reviles so we can see what the Gateway is and what the DNS is.

Also, when the internet stops working through the browser can you still access the internet at the command prompt. Try pinging yahoo after it stops in the browser. If you can ping yahoo then we know the problem is in your browser and not the router. Also try pinging yahoo by its IP to see if it is a DNS issue. I think ping 67.195.160.76 will do it. If it pings with the IP but not the FQDN then try putting the IP in the browser.

See the ip routing = yes? That means its going thru the server. No proxy involved.

KD did you engage RRAS or ICS to do this?
Any scheduled tasks on the server?
Running any GPO's?

Lets see a ipconfig /all from a workstation. Thx

Well the ping test was just to verify that it is not a DNS issue. If you are having problems with the DNS then you would be able to ping yahoo through the IP but not through the FQDN. I did not know that you where using this computer as the gateway for your network. Most gateways I have seen use Linux because it is just too expensive to use Windows for such a simple function.

This seems like this is your Public connection...

Its a little strange to have a Dynamic IP for your public side but not unheard of because ISPs do this all of the time so they can make you buy a Static IP.

So, who is in-charge of your WAN side of the network, would that be you?
Do you have a Firewall Between this computer and the WAN or is this computer acting as the firewall? Remember 2008 now has outgoing firewalls too that need to be configured.
Are there any other computers on the 75.105.152.0 network and are they having the same problem?
One last thing, can you post your ROUTE PRINT? Maybe you lost something in the routing table.

Curious as to how a scheduling issue with internet would be affected by a route? I am not seeing the connection.

KD your server is running ipv6 and your workstation is not or has a issue with ipv6. That is what the "?" are all about in your workstation post.

This has nothing to do with this 5 hr cutout of the internet.

I would suggest the next time you experience this internet outage go to the server and see if it has internet access.

We need to determine if the break is due to the server or due to the ISP

I have the external NIC set to odtain an IP address automatically and my ISP (wildblue.com) provides the setting above the Internal NIC is as static IP.

I us the firewall in 2008 when i had a outage i turned the firewall off with no luck still gets blocked.

When i have a outage the internet works on the server and thats were it stops all the PC on the network get blocked.

Look at the event viewer logs in the timespan internet goes out. Any services stopping? Any errors that may give us a clue? Look at the dns log also.

Interesting that its now 7 hrs before a cutout.

Time correct on the server?

If you tracert yahoo.com during the time the internet is operational and then when its not working from a workstation where does the tracert fail?

When internet is not working can you ping from the server to the workstations?
