Stopping maintenance mode

Hi,

I was trying to run your script and I'm getting the errors like:

Method invocation failed because [System.Object[]] doesn't contain a method named

'GetRelatedMonitoringObjects'.

At C:\MaintenanceMode-test.ps1:24 char:56

+ $healthServices = $computer.GetRelatedMonitoringObjects( <<<< $healthServiceClass)

Does the script run for SCOM 2007 or MOM 2005 only? What may be a problem?

You cannot call a method on a null-valued expression.

I ran the script from its absolute path.

Any help is appreciated.

$computer = get-monitoringobject -monitoringclass:$computerClass -criteria:$computerCriteria

For some reason the value of $compter is Null.

That is the reason it is not able to access the method to stop the maintenane mode.

I have valid values for $computerClass and also $computerCriteria but still have a null Value being returned by get-monitoringobject
