Hi, I have an SCCM infrastructure where all servers running SCCM roles are on Windows 2008 R2 with SP2. I find myself having to install DPs and maybe PXE roles on Windows 2008 Non R2 (Not R2 and R2 also have different versions of IIS). Can anybody tell me if this is supported? That is, to have Windows 2008 non R2 with some SCCM roles (DP, PXE...etc) Thanks, Jesmat.

You can mix those operating systems as much as you want as long as you follow http://technet.microsoft.com/en-us/library/ee344146.aspx

Thank you Torsten! Jesmat.
