On your SBS 2011 [gs server], do you find a lot of DCOM errors in your System Event Log? These are relatively common on SBS boxes. Microsoft’s guidance is that these can be safely ignored. However, when an error is reported, I expect it to be something that should be investigated. If it can be ignored, it shouldn’t be reporting it as an error.
Fortunately, there is a fix for these.
Each event listed below is has the same alert level of “Error” and the same Event ID “10016″. The fixes are all mostly the same with a few differences. Below, I outline each specific error I saw on a specific SBS 2011 box and highlight the differences in fixing each different error.
The key differences are the different user account account missing the rights and the different CLSID and APPID. If you find other DCOM errors that this fix works on, let me know and I’ll add it to the list.
