Very helpful link.
Im not 100% on which errors would impact it, but I seem to have a lot of the following in the system category:
"The McAfee SpamKiller Server service failed to start due to the following error:
The service did not respond to the start or control request in a timely fashion.
For more information, see Help and Support Center at [url="http://go.microsoft.com/fwlink/events.asp.""]http://go.microsoft.com/fwlink/events.asp."
Timeout (30000 milliseconds) waiting for the McAfee SpamKiller Server service to connect.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp
Not sure if that is the error that is causing the issues. I had a few other warnings, but that one seems to happen most frequently..
