YYYY-MM-DD HH:MM:SS.xxx >> XXX >> [ERR] SCOM connectivity error: unknown or non-specific errorMicrosoft.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.GetGroupName(IImpersonation identity)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 SquaredUp DS on a server without the SCOM components
