# 4780(S): The ACL was set on accounts which are members of administrators groups.
**Applies to**
- Windows 10
- Windows Server 2016
Every hour, the domain controller that holds the primary domain controller (PDC) Flexible Single Master Operation (FSMO) role compares the ACL on all security principal accounts (users, groups, and machine accounts) present for its domain in Active Directory and that are in administrative or security-sensitive groups and which have AdminCount attribute = 1 against the ACL on the [AdminSDHolder](https://technet.microsoft.com/en-us/magazine/2009.09.sdadminholder.aspx) object. If the ACL on the principal account differs from the ACL on the AdminSDHolder object, then the ACL on the principal account is reset to match the ACL on the AdminSDHolder object and this event is generated.
For some reason, this event doesnt generate on some OS versions.
