Internet Explorer, Wine? Parallels?

I just purchased my first MacBook Pro, and I have to run Internet Explorer for work. Its the only browser that will work with my portal.

Is there any programs that will run IE other than parallels? I tried wine and cant figure it out.

Any suggestions would be great.

Thanks

I would definitely suggest Parallels or Fusion for this. It would be real straightforward. You will need a legit OS that meets certain requirements though.

I use parallels now, i was just hoping for a more efficient way.

What kind of portal is it? I've found that often, IT techs are quick to jump the gun and say things like "you have to use IE".
