Get-VM is doing nothing for Hyper-V

We have Windows 2008 R2 on our server. We are trying to write a PowerShell script to start/stop our VMs, but the get-vm command isn't working. There is no error message. The command is just not returning anything, but should be. The code looks like this: ``` $temp = Get-VM -Server usa..... | where-object {$_.State -eq 'Running'} ``` We tried doing ``` $temp = Get-VM -name VM-VMNameAsSeenInHyperVMgr ``` and it doesn't return anything either. We installed the update for PowerShell to get version 3 and that made the get-vm command work (not give error message), but it's still not returning any VMs. I saw the forum post PowerShell "Get-VM" error. But Hyper-V is installed now and shows up when I type at the PowerShell command line ``` Get-Module -listavailable ``` At the start of my code I have ``` import-module Hyperv ``` There's also this: ``` [system.net.dns]::GetHostEntry(ip) ``` works and so does Get-Host. We tried ``` Enable-WindowsOptionalFeature -FeatureName Microsoft-Hyper-V -All ``` but the command wasn't recognized as the name of a cmdlet. I tried disabling UAC like this link , but it didn't work. This link shows commands I used: http://www.ehloworld.com/1026 When I typed ``` Set-UACStatus -Computer usa...net -Enabled [$false] ``` it gave the error message that Set-UACStatus wasn't recognized as the name of a cmdlet, etc. either. It didn't recognize Get-UACStatus either. I'm not sure if there's another thing I need to import to use Get-VM. Or my co-worker was thinking maybe we're running into unknown AD issues. I think if it was Active Directory, it would be giving an error message about not having permission to do something, but it's not.
