@msff-amman-Itofficer said in what windows server should I choose for Active directory?:
For me, it depends on the clients/users OS. For example if I have an environment full of Windows 7 SP1 users f go with 2008 R2 SP1
Due to I believe that server OS would've been tested plentiful using that client OS.
If you have mixed bag of client OS, go with the latest.
This argument is still invalid. Why would you go out and purchase an old operating system, to support your old work stations?
You upgrade or run the most current (outside of beta software) because it offers you the most benefit, and comes with support for the longest period of time.
Server 2016 is completely compatible with Windows 7 (which is now 8 years old). Running Server 2008 is even older than Windows 7!
You'd purchase CALs for whatever clients / users you have no matter what, but never purchase out of date software, to support other out dated software.
