ping IP but not netbios name

[Greenbean]

I recently lost my internet connection from all of the computers in my Windows 2003 home network. I use Small Business Server 2003 and use Cable Internet with Charter Communication. I have a SMC Barricade Router.

From any of my PCs I can access my home network resources but when I try to connect to the internet, I can Ping an IP Address but not the NetBios name. This causes my Internet Explorer not to get to any webpages

It certainly must be something with my DNS settings but I don't know where to start. Need help

NetBIOS and DNS are different things. For Internet stuff, it's DNS all the way.

The nslookup tool is useful for troubleshooting this sort of thing. You can type "server ipaddress" to pick a specific DNS server, and just type a name or IP address by itself to resolve it.

So I'd start with this (put your router's IP address in for the first one):

nslookup
server 192.168.1.1
www.google.com
server 209.225.8.42
www.google.com

If the first one fails but the second one succeeds, the DNS resolver in your router is flaky (not that uncommon, unfortunately). In that case you should be able to work around it by manually configuring each PC to use 209.225.8.42 and 24.240.141.241, both of which are Charter DNS servers.
