I'm having a problem with one of the computers on my network. When the user goes to https://accounting.quickbooks.com/, she gets the following error:

Firefox is able to acces, but only has limited funtionality.

What I have done:
1) I have tested the SSL using fortify.net. Using firefox I get "AES cipher, 256-bit key", but with IE, I get "Triple-DES cipher, 168-bit key".
2) I clicked on Help -> About and cypher strenght says 128 Bit. I have editied the Advanced IE options for SSL/TSL many times and in every comination possible.
3) I have re-installed IE6 and upgraded to IE7.
4) I have re-installed Win2000 High-security pack.
5) I have used the batch file found here http://meikleprogramming.com/main/node/24
