Website unreachable

[tcharp]

I've been having what is turning out to be a very tough problem. I seem to have exhausted other resources that I have tried in finding a solution.

I'm finding that I cannot access the Southwest Airlines website at Southwest Airlines

In checking with some friends that are running Vista, they report no problems getting the website to load.

I have a dual boot machine and have no problems getting the website to load when I'm booted into XP but it will not load when my computer is booted into Vista. It times out. A tracert command also times out on the 9th hop.

While I don't believe this is a network problem, I have reset router and swapped network adapters without success. I have also executed the following commands without success:

ipconfig /flush
netsh int ip reset
netsh winsock reset

I have also tried accessing the website with just the numeric IP, still with no success.

I'm pretty stumpped by this and would appreciate whatever ideas you might have.

Thanks,
TC Harp
