An Audit Collection Service forwarder may be unable to retrieve the distinguished name for the ObjectGUID in the collected events in System Center Operations Manager 2007 Service Pack 1

Consider the following scenario. An event contains certain fields that are formatted as an ObjectGUID. The ObjectGUID requires a lookup to Active Directory to obtain the distinguished name of the object. A new event is generated when the Audit Collection Service (ACS) forwarder obtains the event. However, immediately after the new event is generated, the lookup value in Active Directory may not be available. In this scenario, a lookup failure occurs, and the forwarder forwards the event that contains the ObjectGUID instead of the distinguished name to the collector.

How to create a required registry key on affected agents

This hotfix lets you create a new registry key on affected ACS Forwarders. This registry key allows for a retry on any ObjectGUID that cannot have its distinguished name resolved on the first attempt. This registry key must be created on all affected ACS Forwarder roles because it does not exist by default. A suggested initial retry value in milliseconds is provided. The retry value may have to be tuned, depending on the environment.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: To create the required registry key on affected ACS Forwarder roles, follow these steps:

1. On an ACS Forwarder role, use Registry Editor to locate the following registry subkey:
   HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\AdtAgent\Parameters
2. Under the following subkey, create a new DWORD value key that is named RetryDelay and that has a value of 100 (decimals):
   HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\AdtAgent\Parameters
3. Stop and then restart the Operations Manager Audit Forwarding Service from the Services MMC snap-in so that the value can take effect.

Note The RetryDelay value is the number of milliseconds (ms) that the forwarder will wait before the operation is retried. An initial value of 100 ms is suggested. If the initial value is unsuccessful, increase the value 20 ms at a time, restarting the Operations Manager Audit Forwarding Service every time for the new value to take effect. If the RetryDelay value is too large, unwanted ACS Forwarder performance issues may occur. Keep the value as low as possible for successful distinguished name resolution.
