The following error appears in a SharePoint Server 2010 farm server system log:
Log Name: System Source: Microsoft-Windows-DistributedCOM Date: [date] Event ID: 10016 Task Category: None Level: Error Keywords: Classic User: [domain]\[FarmAccount] Computer: [FarmServerName] Description: The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID {000C101C-0000-0000-C000-000000000046} and APPID {000C101C-0000-0000-C000-000000000046} to the user [domain]\[FarmAccount] SID... from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.
This error is being logged to the System event log due to the farm account not having permission to access the DCOM component at 000C101C-0000-0000-C000-000000000046.
If after changing the key ownership, you find that these options are still disabled, close Component Services and then re-open it.
When initially added, the account will only have (Allow) Local Launch checked.
You may see your administrator group here and think that you can set Full Control for your group. However, if you try this, you will get an Access is denied error prompt
By default, the Current Owner will be the TrustedInstaller account.
