SCOM 2012 APM “An unhandled exception has occurred” event 1309


Within System Center Operations Manager 2012’s Web Console installation, the setup installs Application Advisor and Application Diagnostic – both, Application Performance Monitoring (APM a.k.a AVICode) components.

It’s all nice and good, but you may found yourself dealing with the below error while trying to access the Application Advisor and Application Diagnostic URLs:

“We apologize for any inconvenience caused by the temporary service outage”  ? A quick look at the event viewer will show us the below Warning (not the full data from the event):

Exception information:

Exception type: OleDbCommandException

Exception message: Login failed for user ‘NT AUTHORITY\ANONYMOUS LOGON’.


Connection: Provider=SQLOLEDB;Server=SQLSERVER\SCOM;database=OperationsManager;Integrated Security=SSPI;


Well, “Login failed for user ‘NT AUTHORITY\ANONYMOUS LOGON” – Let’s go to the IIS Manager and navigate to the Application Pools, there you will see too applications pools named OperationsManagerAppMonitoring & OperationsManagerMonitoringView which configured with “ApplicationPoolIdentity” – not good for us !

Setting these pool’s identities to domain user which has permissions to the DB mentioned above (“Provider=SQLOLEDB;Server=SQLSERVER\SCOM”) will do the job.


Next, please recycle the pools and.. walla…
