问题
Hey I am very new to PowerShell and found one of Ed Wilson's helpful scripts on his blog: http://blogs.technet.com/b/heyscriptingguy/archive/2012/11/12/force-a-domain-wide-update-of-group-policy-with-powershell.aspx.
I needed to customize it a little for my needs and just need some help getting the right code down.
I will just use his code because all I did was replace it with my credentials and AD info:
$cn = Get-ADComputer -filt *
$cred = Get-Credential iammred\administrator
$session = New-PSSession -cn $cn.name -cred $cred
icm -Session $session -ScriptBlock {gpupdate /force}
What I added was the next two lines to attempt to pause the script to allow the gpupdate to process then restart the computer(s):
Start-Sleep -s 120
Restart-Computer -ComputerName $cn.name
When I run the script all together it seems to just hang after I enter my credentials. My guess would be it doesn't like the way I present the Start-Sleep cmdlet because I can run the Restart-Computer cmdlet with success without Start-Sleep. The problem is it doesn't wait for gpupdate to finish so the policy doesn't get pushed. I do not get any errors when I run the script, it just hangs. I have left it running for about 10 minutes with no success.
I appreciate any help or suggestions to make this script work properly. Thanks in advance for any input.

There's nothing wrong with your sleep invocation but it isn't the best way to go. You can wait on the job to finish with a timeout (in case the command hangs) e.g.:
$job = icm -Session $session -ScriptBlock {gpupdate /force} -AsJob
Wait-Job $job -Timeout 120
Remove-PSSession $session
Restart-Computer $cn.name

@Keith Hill is right, sleep looks good. Another thing you can do is push the sleep/restart commands onto your target machines:
icm -Session $session -ScriptBlock {
gpupdate /force; Start-Sleep -s 120; Restart-Computer -Force}
