Dear all,
I have installed MS Exchange 2013 and MS Exchange 2013 CU1 several times (maybe 10 times) on Exchange 2012 servers in different test environments. Sometimes the Error "C:\Windows\system32\inetsrv\config\ApplicationHost.Config'. The configuration file may be corrupted."." was shown directly after the installion, or in some cases Exchange 2013 was running fine a view days or weeks and suddenly the Exchange Server 2013 is offline and shows this error in the event log. What is going wrong here, because I think this a generally bug?
