Hi @Oliver
The Admincount is set to 1 automatocayy by the process SDProp for accounts and group with high privilege in the domaine.
But when you remove a account from high privilege group , the admincount still keeping the same value 1. So in this case you should reset it manually.
There is no impact to reset admincount manually. If you reset by mistake a high privilege account , SDProp will set it again the value 1 I have a script to cleaup Admincount automatically on non provilige accounts
