This idea of this post is to help those unfortunate enough to be looking for an SCCM 2007 r3 standalone trial. Microsoft offers an SCCM R3 Trial, but it’s the R3 upgrade only. Furthermore, if you try to install the R2 or R3 upgrade trial on the SCCM 2007 R1 trial, you’ll get an error message about the server being in evaluation mode. This means that’s it’s currently not possible (as far as I can tell) to evaluate the latest and greatest version of SCCM currently released (as of this blog post date). Very frustrating.
The good news is that SCCM 2012 is awesome and Beta 2 is available as a 180 trial. I still can’t get multicast working on either version though :(.
