    @sashar-msft yes I am currently having this issue. I have installed the most recent version of AD connect on Windows SBS 2011.

    Unfortunately, Azure AD Connect cannot be installed on Small Business Server. The server must be using Windows Server standard or better. Please refer to Azure AD Connect prerequisites documentation for details.
