What’s going on? The service account specified for “Windows Service – SharePoint Server Search” does not have permissions in DCOM to launch and activate.

The fix:

1. Go to the Control Panel on the SharePoint application server running search
2. Launch Component Services
3. Browse to Component Services – Computers – My Computer – DCOM Config – OSearch14
4. Right-click OSearch14 and choose Properties
5. Go to the Security tab and click the first Edit button (under Launch and Activation Permissions)
6. Add the domain\username of your service account and make sure the check boxes for Local Launch and Local Activation are checked

You should no longer receive Event ID 6482 errors.
