Numerous errors and very slow load times tonight

[MikePA]

I'm certain it is on my end but even though I get a Page Cannot Be displayed in IE or just a blank page in Firefox...
I have a Dell Vista box and I am quite certain is has to do with either IE7 or the Vista or something between the two. I can take my old PC with XP and surf all day and not have this problem. This is the only site I can definitively say I have the problems with and it gets pretty frustrating. This is just about my favorite site!

Since you see errors with both IE and Firefox, I'd guess it has something to do with Vista.

Perhaps Bird's suggestion will help.

I know Microsoft claims they addressed a number of security issues with WindowsXP in Vista, it could be something Vista is preventing but XP allowed.

I don't have Vista so I'm not sure where to look, but in XP, you can go to

Control Panel
Administrative Tools
Event Viewer

to look at the Security, System and Application logs. If you right click on each log, you can Clear All Events. No need to save them.

Access TBN and reproduce the error.
Immediately look at all 3 logs

Maybe there'll be some helpful information there.
