I have DNS but no Internet on Windows Server 2003 - HELP!

[palindrome]

Suddenly my server stopped being able to access the internet today. It is able to pull the proper DNS and can even ping webpages from the command prompt. But, I am unable to access the internet. Anyone willing to point me in the right direction?

PS - All of the other computers on the network can still access the internet, so the problem on the server only.

What about using telnet to try and connect to a remote web server on port 80? That will at least tell you if it's system wide or browser specific.

Tell me what i have to do for telnet. Sorry I'm not a server guy


Also, I tried "netsh int ip reset c:\reset.log". Everything cleared and reset, but no change in the ability to access the internet.

telnet anywebserver.com 80

If you get a timeout then something is preventing outgoing connections destined for port 80.

If that doesnt work, I'm going to reinstall the driver.

Ok, I did the "telnet www.google.com 80" and it flashed with a line and went back to an empty prompt. I assume that means I got out.

I installed a new driver for the NIC, 6 years newer, still not dice. I'm going to install firefox and try that...

Did you check your proxy settings? Perhaps the server was setup to go through a proxy for web traffic and the proxy either moved or is down?

Not sure where to go from here, think the NIC might be bad?

No proxy or proxy settings. This is a very basic small office type setup.

I appreciate your help btw.



I just can't get my head around that I have DNS, I can ping, I've reset everything on planet earth and still can't browse...

Check out this screen shot of my tracert to google.com

Well, DNS uses port 53 while http uses port 80, so a firewall anywhere along your route to the internet could be preventing your from connecting to web servers but still allow you to use DNS. Your trace looks just fine, I ran one to the same IP and my last two hops are the same as yours.

No firewall to speak of. Plus the telnet didn't hang when assigned to port 80 (but did on the default port of 23). I'm baffled here...

Maybe the PCI slot on the motherboard is going out?

EDIT: Also, the server cannot access the local router, when all the other computers on the network can.

Ordered a new NIC card, hopefully that will solve this problem.

From the SERVER, can you browse a web site HOSTED by itself??
