You will need to run the below in Powershell. This will update the Managed Services Account with the default GUID.
$DomainDN = (Get-ADDomain).distinguishedName $TargetOWKOIDString = "1EB93889E40C45DF9F0C64D23BBB6237" # Identifier for wellknown SID.  $TargetOWKOTemplate = "B:32:$TargetOWKOIDString`:{0}" # String.Format replacable string. $TargetDN = "CN=Managed Service Accounts,$DomainDN"
$OtherWellKnownObjectsOG = (Get-ADObject -filter "objectClass -eq 'domainDns'" -Properties otherwellknownobjects).otherwellknownobjects $TargetOWKOIndex = $OtherWellKnownObjectsOG.IndexOf( $OtherWellKnownObjectsOG.where({ $PSItem -like "*$TargetOWKOIDString*"})[0])
Set-ADObject -Identity $DomainDN -Add @{ 'otherwellknownobjects' = ($TargetOWKOTemplate -f "$TargetDN") } -Remove @{ 'otherwellknownobjects' = $OtherWellKnownObjectsOG[$TargetOWKOIndex] }
(Get-ADObject -filter "objectClass -eq 'domainDns'" -Properties otherwellknownobjects).otherwellknownobjects
