Check Text ( C-46753r723467_chk )
Open "Windows PowerShell" on a domain controller.

Enter "Get-ADComputer -Filter {(TrustedForDelegation -eq $True) -and (PrimaryGroupID -eq 515)} -Properties TrustedForDelegation, TrustedToAuthForDelegation, ServicePrincipalName, Description, PrimaryGroupID".

If any computers are returned, this is a finding.
(TrustedForDelegation equaling True indicates unconstrained delegation.)

PrimaryGroupID 515 = Domain computers (excludes DCs)
TrustedForDelegation = Unconstrained Delegation
TrustedToAuthForDelegation = Constrained delegation
ServicePrincipalName = Service Names
Description = Computer Description
Fix Text (F-46710r723468_fix)
Remove unconstrained delegation from computers in the domain.

Select "Properties" for the computer object.

Select the "Delegation" tab.

De-select "Trust this computer for delegation to any service (Kerberos only)"

Configured constrained delegation for specific services where required.
