There are quite a few ways to tell. Here are a few I found.

The correct version of the ADPrep.exe tool for Windows Server 2003 R2 is 5.2.3790.2075.

The value of the Schema Version registry subkey and the objectVersion attribute are in decimal.

  • 44=Windows 2008

I ran into that issue today, thanks to petri.co I found the answer and I thought I’d share.
