Server 2019 Essentials user licensing limitation
I have an environment where Windows 2019 Essentials is the domain controller. There are 9 user accounts in the environment. The SILSVC logs state that there are 43 user accounts in the AD and that licensing is in violation. This status causes the Essentials DC to shutdown once every 7 days.
Investigation has shown that the variation between the 9 user accounts and the 43 reported is accounts created for services attached to applications in the environment. With Essentials 2016 there was a way to not include accounts created for services from the licensing count by hiding them from the GUI management application using set-wssuserdashboardvisibility.
With Windows server 2019 Essentials is there a way to not include accounts created for services in the count of users toward the 25 user account limit?
Well, the Product Terms state for Essentials server edition explicitly "25 user accounts" - emphasis is on the word "accounts". For all other products, like CAL, normal Windows Server etc there is no rule specific to the (technical) account, but only the "user" - defined as the person. So from a licensing perspective I tend to say that even when you would be able to do what you described technically, it does not change the fact that there are more accounts as license terms allows.
Relevant text in Product Terms (https://www.microsoft.com/en-us/Licensing/product-licensing/products😞
"Customer may use up to 25 user accounts. Each user account permits a named user to access and use the server software on that server."
And - the same statement was there for Windows Server 2016 Essentials btw.
@samlhc I'm not sure I understand - you can look up the number of accounts the current server is configured for in the same area where you have defined the user accounts. When the server is shutting down every 7 days, and only 5 accounts are created it might also be to other reasons (e.g. you moved FSMO role from the server).
