Neither live.com or hotmail.com working or pingable. No malware found.

I ran into an interesting program this morning. I have a business customer that has his outlook setup to check his hotmail account. As of Sunday, he can't send or receive messages and can't login to the webmail.

I tried the most obvious things. Manual virus check, TDSS Killer, GMER, Combofix, HijackThis, Malware Bytes, etc. all clean. Winsock reset, Norton & McAfee Removal tools multiple times, flush DNS etc. Nothing. All hardware diagnostics come back clean, all drivers updated, clean Hosts file, reinstalled network driver, still nothing.

The funny thing is, all other computers on the network can connect. If I go to login.live.com I can connect, but hotmail.com and live.com do not work. Pinging also doesn't work to either address or pop3.live.com or smtp.live.com.

I am totally out of ideas. Any tips?
