DCOM Properties greyed out in Windows 2008 R2

The system event log can get full of these types of message, it usualy means a DCOM service needs additional permissions to be set. But in Windows 2008 R2 you will find the DCOM settings are all greyed out. This is by design and you will not have permission to change these settings until you follow the guide below.

1. Event Log ID 10016


Look for the Event Log ID 10016 in the System Log and then open the event. Take note of the GUID that is referenced.

2. Search Registry


Open regedit32 and search for the GUID.

3. Key Permissions


When the key is found right click on the key and choose permissions.

4. Advanced Permissions


Click on the Advanced button.

5. Owner


Click on the Owner tab and then note the current owner is TrustedInstaller.

6. Change Owner


Click on the Security Group you want to change ownership to and then click Apply to change this. Note the change of current owner.

7. Change Permissions


Return to the permissions properties and highlight the Security Group you want and then assign the Full Control permission.

8. Confirm DCOM Properties


Open the DCOM MMC and you will see that the properties for the DCOM object are now not greyed out.
