Description
Unconstrained delegation enabled on a computer can allow the computer account to be impersonated without limitation. If delegation is required, it must be limited/constrained to the specific services and accounts required.

Check Text (C-243478r959010_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.
