I noticed a question that was heavily concerned with Active Directory that did not have the active-directory tag but rather used the windows-domain tag. As of this moment there are 382 questions tagged with windows-domain and 2,361 with active directory.
I've proposed a tag synonym from windows-domain to active-directory.
Is there ever a time when the concept of a domain within active directory should be tagged separately from active-directory? And if so, wouldn't it be better to keep the tag symmetry by naming it active-directory-domain which would leave open the possibility of active-directory-forrest and active-directory-site?
##EDIT 1: NT Domains
As John Gardeniers points out in the comments, NT4 domains are likely to still exist even in 2012, and that is not Active Directory.
New Suggest: All NT4 domain related posts should be tagged with something that clarifies that it's NT4. How about nt4-domain? Of course, this then means that the windows-domain posts would need to be winnowed for which ones are referring to NT4 and which are truly referring to AD.
