Can't Access An IP From Home Network

[em2ab]

Hey guys, I'm at my girlfriend's house and for some reason not a single computer on her network can access any of my websites that I have with the same hoster. Not sure if she's actually set up on a network but I know she's got a single cable modem hooked to a router with 2 desktops wired to it and it's also wireless so a laptop can hook on wirelessly. Out of these three computers, none of them can access my websites. They used to be able to but someone messed with the router and now she can't. Anyone know what could cause it? When I use a URL redirect page like people use at work to access Facebook and stuff, I can get to it no problem. But that doesn't allow me to log in at all, I can just view.

So to clarify, she cannot access any of my three websites, she can't even access the homepage of the hosting provider which is even more bizarre. So basically anything on that server is inaccessable from behind this modem. All other websites work fine. The hoster is www.hostgo.com and when I try to ping it from the command prompt, it gives me the following...

C:\Documents and Settings\Ferraro>ping www.hostgo.com
Ping request could not find host www.hostgo.com. Please check the name and try again.

If you connect a PC directly to the modem are you able to access these web pages? Do the URL's resolve via DNS?

Never tried hooking the computer right to the modem, her dad does important work for his business and I didn't want to mess up anything. What do you mean by the URL resolving?
