And you believe that in shops of 50-100 workstations it's the general rule that they run their networks without any domain security?
Around 75 or so is when they really start noticing that, but yes.
I’ve walked in on entirely too many 50+ Windows workstation sites in the course of contracts where there was no domain server at ALL. (I do contracting as well as straight up consulting.)
A clarification: I have never seen a network (outside of a school) with more than 100 Windows workstation that didn’t have a domain controller, etc.
I have seen far too many 100-and-under networks that didn’t.
