PhoneFactor might do the trick:

Free too for < 25 users I believe. – gravyface Oct 14 '11 at 16:05
It is. I've used it to provide two factor authentication for web services. – joeqwerty Oct 14 '11 at 16:07

If you use Radius for authentication, all the major two-factor authentication systems are options for you. You probably need to run the RDP through ISA.

Here's a tutorial I wrote some time ago: Note that IAS has been replaced by NPS in 2008+.

we don't use radius, because we are looking for a "simple and affordable" solution ;) – perler Jan 20 '12 at 20:19
hmm, I find radius to be pretty simple. And free since the MS radius plugin is free and on linux, freeradius. – nowen Apr 18 '12 at 16:20
