STIG Description
This STIG is applicable for all Windows servers if a forest architecture is implemented for the Active Directory (AD). The settings required by each check will be applied to each Forest as a whole. This STIG does not apply if a forest is not implemented. The system must also be hardened using the Windows 2003 (or 2003 R2) or Windows 2008 (or 2008 R2) STIG. The system must also be reviewed using the applicable Windows and AD Service STIG, depending on the Windows version installed on the server. Comments or proposed revisions to this document should be sent via e-mail to the following address: disa.letterkenny.FSO.mbx.stig-customer-support-mailbox@mail.mil.

When the Windows Time service is used to synchronize time on client computers (workstations and servers) throughout an AD forest, the forest root domain PDC Emulator is the normal default to...
V-8527	Low	Changes to the AD schema must be subject to a documented configuration management process.	Poorly planned or implemented changes to the AD schema could cause the applications that rely on AD (such as web and database servers) to operate incorrectly or not all. Improper changes to the...
