Hi, We have installed windows SBS 2011 and have a SolidWorks Program which they say only supports Windows Sever 2008R2. I read that SBS 2011 was built on Windows Server 2008R2. My question is if SBS 2011 is Windows Server 2008R2 with other packages added or is it a lighter weight version of Windows Server 2008R2? My next question is if the SBS2011 is lighter weight can I convert that license and cals to Windows Server 2008R2? Thanks, Andy
