Hello,
If you have some equipments that can’t understand the SID compression (NAS), you’ll need to disable it, you can do it with that registry key:
HKLM:SOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystemKDCParametersDisableResourceGroupsFields
If you put that key to 1, you disable it.
Disable SID compression on Directory Services 2012R2
Set-ItemProperty -Path HKLM:SOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystemKDCParameters -Name DisableResourceGroupsFields -Value 1
Enable SID compression on Directory Services 2012R2
Set-ItemProperty -Path HKLM:SOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystemKDCParameters -Name DisableResourceGroupsFields -Value 0
