Am I Blocked? Proxy Servers...

That would be caused by DNS issues, but tracking down the problem isn't always straitforward.

Check the IP configuration of her network adaptor by typing ipconfig \all at a DOS prompt. If the output is too long, you might want to redirect it to a text file with ipconfig \all > ipconf_output.txt.

There should be entries for a DNS server listed in the output. Try pinging them in a DOS prompt with ping xxx.xxx.xxx.xxx where xxx.xxx.xxx.xxx is the IP address of a DNS server.

You should also double-check that there isn't an overriding entry in the Hosts file (located in the <boot drive>\<Windows folder>), since any entries in that file are considered first before querying a DNS server.

Jam it back in, in the dark.
