We are running above server. Today all user can't connect to ad.
We encountered an error in eventlog that CheckEssentialsSKUUsersLimit was executed and that the maximum amount of domainuseraccounts exeeded. Windows Server 2012 R2 Essentials only support 25 domainusers....
We counted user and ended at 22.
Do we have to count all the builtin-users and other users that have been created by system (e.g. DiscoverySearchMailbox, IUSR_MY_SERVER_NAME, IWAM_MY_SERVER_NAME, ...)?
If we do, we reach 50 users.
So, is there any blocked cal? Is there any possibility to deblock old licenses (from older pc)?
What should we do?
Thanks for your help
