No Internet, Only Intranet

By mmorse ·
I have a Dell Latitude D800 laptop. I have it a network. The computer can't ping out to the internet. I rejoined the computer to domain, but it only will see the intranet. The network is just set up with a PDC and not active directory. The DNS server resolves all the internet sites, but won't ping them! HELP.

Firewall?

by mjfera In reply to No Internet, Only Intrane ...

What separates your internal network from the Internet?

This could be caused by many different things. It could be as simple as ICMP being blocked by a firewall or router. Or, it could be a deeper routing issue within the bounds of your internal network.

First, make sure ICMP is enabled. As an alternative, you can attempt to telnet port 80 on a well-known web-site. For example:

"telnet www.google.com 80"

Ping is only a good check of connectivity if all firewalls in the path allow ICMP packets to pass.
