Registry hacks to turn-on verbose GPO logging


The default logging levels for GPO processing in Windows 2000 are minimal.
Applications don’t log to the Event Viewer when they make registry changes Event
Viewer. GPO processing logs some high-level events in the Event Viewer, but
they’re not a great deal of use if you run into problems. The following registry
hacks will help allowing you to change from default to verbose logging.

RunDiagnosticLoggingGroupPolicy will turn GPO event logging to verbose.

Hive: HKEY_LOCAL_MACHINE
Key: Software\Microsoft\Windows NT\CurrentVersion\Diagnostics

Name: RunDiagnosticLoggingGroupPolicy
Type: REG_DWORD
Value: 1
Note: After you make that change and restart the
system, you will see a lot more information reported, especially during errors.
In many cases, this will be enough to get the information you need.

RunDiagnosticLoggingApplicationDeployment will turn on verbose logging
specifically for GPO application deployments.

Hive: HKEY_LOCAL_MACHINE
Key: Software\Microsoft\Windows NT\CurrentVersion\Diagnostics

Name: RunDiagnosticLoggingApplicationDeployment
Type:
REG_DWORD
Value: 1
Note: In the case of an administrator who is
trying to deploy antivirus files or other apps via GPO, this key would
definitely be helpful in improving logging.

RunDiagnosticLoggingGlobal will turn on verbose logging for all GPO
processing events, including those listed above.

Hive: HKEY_LOCAL_MACHINE
Key: Software\Microsoft\Windows NT\CurrentVersion\Diagnostics

Name: RunDiagnosticLoggingGlobal
Type: REG_DWORD
Value: 1
Note: As a catch-all it will log lots of events
that may not have anything to do with your specific problem.

Beware that when you switch on verbose logging modes with these values, your
Event Viewer logs will fill up quickly. You’ll need to review the settings for
the Event Viewer logs to ensure that everything you need is being logged and
that you don’t lose or overwrite any part of the logs you may need to keep for
reference, security, and/or legal reasons.
