Event 1202 with status 0x534 logged on Windows Server 2008 R2 domain controllers after modifying security policy

When modifying any security setting in the Default Domain Controllers Policy using the Group Policy Management Console (GPMC) from the console of a Windows Server 2008 R2 domain controller, GPMC incorrectly translates the SID for the Wdiservice account in the policy to a user name which is not recognized by the local machines where the policy is enforced.

This issue also occurs when a Windows 7 or Windows Server 2008 R2 member computer modifies any security setting in the Default Domain Controllers Policy on a Windows Server 2008 R2 domain controller.

Edit the %SystemRoot%\Sysvol\domain\Policies\{6AC1786C-016F-11D2-945F-00C04fB984F9}\MACHINE\Microsoft\Windows NT\SecEdit\GPTTMPL.INF file:

Replace the value of a SeSystemProfilePrivilege: *S-1-5-32-544,NT Service\WdiServiceHost (initial value: *S-1-5-32-544,WdiServiceHost).

If you use IIS on server:
Add the “IIS AppPool\” prefix to ‘DefaultAppPool’ and ‘Classic .NET AppPool’ object.
