The thing that confuses me is my Windows 7 box has worked for 2 or 3 months. The XP machine worked for closer to 2 years. The problem started yesterday morning.
If I do ping www.google.com it times out time and time again. The instant I issue a flush on the MT the query starts working. I can see the www.google.com CNAME and the A name associated with it every time I look on the MT.
