There are a few things which may be helpful if you installed Exchange Server 2013 CU2. If you have a virtual machine and you keep getting a blue screen or failure., I have two things which may help:
2. Monitoring System configuration change along the lines of
Add-GlobalMonitoringOverride -Identity exchange\ActiveDirectoryConnectivityConfigDCServerReboot -ItemType Responder -PropertyName Enabled -PropertyValue 0 -Duration 60.00:00:00
3.Install Exchange 2013 CU3
I saw this issue in a production situation recently so please watch your versions if you have this occurring in a virtual machine.
