The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID {61738644-F196-11D0-9953-00C04FD919C1} – SharePoint 2010


After completing a fresh install of SharePoint 2010, if you followed least privileged installation, you may notice the following error being logged into the System events in Event Viewer. This is because the farm admin account, on behalf of which the SharePoint timer service is running, doesn’t have adequate permission on the DCOM component “IIS WAMREG admin Service”. In order to fix this permission issue,

  1. Open Component Service by clicking Start > Administrative Tools > Component Services.
  2. Navigate and expand the node Component Services > Computers > My Computer > DCOM Config.
  3. Right Click the sub node “IIS WAMREG admin Service” and select “Properties”.
  4. 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.
  5. 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.
  6. In the popup window, add the farm admin user account and check Local Launch and Local Activation permissions. The screen should look like this.

  7. Restart IIS and SP Timer. If possible, restart the server itself.
