We get lots of questions about Windows Server. By their very nature, most of these questions specifically involve a business environment and therefore do not belong on Super User, since both the help center and tour state that "issues specific to corporate IT support and networks" are off topic here.
I've already rewritten the tag wiki excerpts for the various Windows Server versions:
windows-server windows-server-2003 windows-server-2008 windows-server-2008-r2 windows-server-2012 windows-server-2012-r2 windows-server-2016
All of these tag wiki excerpts now contain the following text (changed to conform to "Questions about Small Business environments on topic?" and per Hennes's answer):
Questions about administering Windows Server systems that are specific to a business environment are off topic for Super User; please consider asking on Server Fault instead if your question is on topic there.
However, how do we deal with all those questions that are already on our site? Should we vote to close or migrate them en masse? What else should we do?
Of course, I recognize that people may run a Windows Server machine in a home or testing environment for any of a variety of reasons and questions of this sort should not be migrated. How do we distinguish between business and non-business Windows Server questions?
