It doesn't work for me as well with the credentials that you posted in both Firefox and Google Chrome.

Did this ever worked before in Firefox or only in IE?

Two answers first, to cor-el, it did work in both FF and IE, it just suddenly stopped in FF - and to FredMcD, I did all that stuff - same result.

In the end, I appreciate your efforts and thank you, but I have talked to some other IT folks familiar with the site, and it seems that no one else can get at it except in IE - must be something with the site....

Thanks for your efforts again.
