Error Message in the log files

YYYY-MM-DD HH:MM:SS.xxx >> XXX >> [ERR] SCOM connectivity error: unknown or non-specific error
Microsoft.EnterpriseManagement.ConfigurationReaderException: The service type 'Microsoft.EnterpriseManagement.Runtime.ITaskRuntimeService, Microsoft.EnterpriseManagement.Runtime, Culture="", PublicKeyToken="31bf3856ad364e35", Version="7.0.5000.0"' for the component named 'TaskService' cannot be found.

at SquaredUp.Connector.Scom.Authorization.ScomConnectivityTest.Authorize(IImpersonation identity)

Cause

The problem appears to be with loading the SCOM SDK binaries from the Global Assembly Cache if the server has ever had any SCOM components installed on it (e.g Reporting, Web Console)

Workarounds

  • Remove the SCOM Reporting Server component
  • Re-install the SCOM Web Console component if previously installed but has been removed
  • Install Dashboard Server on a server without the SCOM components
