I ran in to this error on a default Single Server install for my customer, a small real estate agency in San Diego. Normally I would have caught this DCOM authentication error in the system log, but instead focused on the symptoms of the problem in the application log, and wasted 60 minutes of time doing so (Bad John). So in order to help save some time in the future, I'll post the quick fix below.
1. Open Start Menu > Administrative Tools > Component Services Tool
2. Drill Down and Expand DCOM Config
3. Navigate to the OSearch, Right Click Properties
4. Select the Security Tab
5. Add the Network Service Account to Local and Activation Permissions
6. Add the Network Service Account to Access Permissions
7. Restart the Office SharePoint Server Search Service from Start Menu > Administrative Tools > Services Tool
