Event ID 10016, DistributedCOM: The application-specific permission settings do not grant Local Activation permission for the COM Server application

There are 2 reg keys you have to set permissions to before you go to the DCOM Configuration in Component services.

First one is CLSID key and the second APPID key.

If you noted above keys, you should use same methodology for different apps that creates Event ID:10016.

Error message:

The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
{C2F03A33-21F5-47FA-B4BB-156362A2F239}
and APPID
{316CDED5-E4AE-4B15-9113-7055D84DCC97}
to the user IIS APPPOOL\DefaultAppPool SID (S-1-…….) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

Solution:

1. Open Regedit.
2. Go to HKEY_Classes_Root\CLSID\*CLSID*.
Note: *CLSID* stand for the ID that appears in your event viewer error. In your case, it’s {C2F03A33-21F5-47FA-B4BB-156362A2F239}.
3. Right click on it then select permission.
4. Click Advance and change the owner to administrator. Also click the box that will appear “Replace owner on subcontainers and objects”(below the owner line)
5. Apply full control.
6. Close the tab then go to HKEY_LocalMachine\Software\Classes\AppID\*APPID*.
Note: *AppID* is the ID that appears in your event viewer. In your case it’s {316CDED5-E4AE-4B15-9113-7055D84DCC97}.
7. Right click on it then select permission.
8. Click Advance and change the owner to administrators.
9. Click the box that will appear “Replace owner on subcontainers and objects”(below the owner line).
10. Click Apply and grant full control to Administrators.
11. Close all tabs and go to Administrative tool.
12. Open component services.
13. Click Computer, click my computer, then click DCOM.
14. Look for the corresponding service that appears on the error viewer.
15. Right click on it then click properties.
16. Click security tab then click Add User. Add SYSTEM then apply.
17. Tick the Activate local box.

So use the relevant keys here and the DCOM Config should give you access to the greyed out areas:
