Computer Monitoring Error Workaround if you have a Mac on your Network
A wiki article is up for those of you who are receiving a computer monitoring error in the Dashboard of Windows Home Server 2011 after installing Update Rollup 2.
There are several reasons that the Alert service will generate “Computer Monitoring Error”, including:
- Client or Server are missing Powershell execution engine.
- An alert evaluation component throws unhandled Exception. (That’s the most common cause we have seen)
- An alert evaluation component can’t find its Feature Definition file that includes the evaluation rules.
- An alert evaluation component does not report results after a certain time.
When these situation happen, those alerts evaluated by that component will never show up. But other alerts or product features will not be impacted.
More information and a workaround if you also have Mac clients in your network can be found here.

Additionally, Susan Bradley has been helping me (us) out determining other causes of the “Computer Monitoring Error”. Apparently another cause of the problem is communication with older routers, See http://social.microsoft.com/Forums/en-US/whs2011/thread/54de4f77-f237-41c6-b3fb-8a1b6d85b4f8 near the bottom.
