Welcome to Androidforums.com we are glad you are here.
As for your question, have you tried Skyfire or Dolphin Browser? They act like IE very well. Wow, just tried both and firefox, no go. To be honest, I do not know if it is possible on android. I'll keep looking and if I find a way, I'll let you know
EDIT = I have looked everywhere I can think of and I was unable to find a solution. It seems there are a lot of people very unhappy with this. From what I can see, the website is coded to ONLY allow a real IE browser; even if you fakeout your browser, it still sees it and blocks entry. Just for the heck of it, I pulled out my old Tilt2 windows phone to see if it would work and I get the same error, looks like this is a windows PC with IE only website.
