Error Message

Remove-SCVMNetwork : VMM is unable to delete the VMNetwork 'Test Network' because other objects, such as VMSubnets, Load balancer templates and  Virtual network adapters depend on it. (Error ID: 15011)

Remove the VMNetwork association with all dependent resources, and then remove the VMNetwork.

To restart the job, run the following command:
PS> Restart-Job -Job (Get-VMMServer localhost | Get-Job | where { $_.ID -eq "{somehash-hash-hash}"})
