The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
to the user IIS APPPOOL\ASP.NET v4.0 SID (S-1-5-82-794271414-2547205055-1060673776-2579641347-304524694) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.
This error is being logged into the System event logs in Event Viewer due to inadequate permission for the farm admin account on the DCOM component 000C101C-0000-0000-C000-000000000046. In order to change
the permission settings, perform the following steps:
Open Component Service by clicking Start > Administrative Tools > Component Services.
Navigate and expand the node Component Services > Computers > My Computer > DCOM Config.
Right Click the sub node “000C101C-0000-0000-C000-000000000046” and select “Properties”.
On the Properties dialog box, select Security tab. In most cases you will notice that the settings are grayed out. This is because the logged in user doesn’t have enough permissions on this component to
change the settings. In order to provide this permissions, perform the steps described in next section “Change Component Service Owner and Permission”. You may need to restart the server after doing this.
Once you set up the permission mentioned in previous step, in the Launch and Activation Permissions section in Security tab, select Customize option and click Edit.
In the popup window, add the farm admin user account and check Local Launch and Local Activation permissions.
Restart IIS and SP Timer. If possible, restart the server itself.
