DCOM Error 10010 The server {7D1933CB-86F6-4A98-8628-01BE94C9A575} did not register with DCOM within the required timeout

We've been experiencing this DCOM error message for the last month or two. It doesn't appear to be doing any harm, but it's worrying that it's happening so frequently.

What steps do I need to take to diagnose the cause and how can I correct this issue?
