.NET ComException (0x800706BE) on Windows Server 2012R2 startup when querying Win32_Service

Bernhard Führicht 1

Hello,

when starting a service automatically on a Windows 2012R2 Server, during the startup of the server the service crashes with the following exception:

Stacktrace:
Exception: System.Runtime.InteropServices.COMException;
at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo)
at System.Management.ManagementObjectCollection.ManagementObjectEnumerator.MoveNext()

When the service is set to "Delayed Start" it works and stopping and starting on the running system works too.

During the service start the WMI-Query ("SELECT * FROM Win32_Service WHERE name like '%SERVICE%'") is made using the System.Management.ManagementObjectSearcher and the result set is looped to check if the service is already running.

Regards,
Bernhard

Since your service depends on WMI being started does your service specify it as a dependency?

No, but according to starting-and-stopping-the-wmi-service "If WMI is not running, it automatically starts when the first management application or script requests connection to a WMI namespace." so it should start automatically on the first request.

Well, why not set the dependency and test to see if it makes a difference?

I can try it and I assume it would work, since the delayed start works too.
Maybe I should have clarified in the question but it works everywhere else except on that server.

The error is "The remote procedure call failed."
Maybe its a timing issue related to starting the WMI service and the configuration of that particular server.
