Running Best Practice Analyzer on remote 2008 R2 domain controllers

Question

Hello Powershell World,
I'll start out by first mentioning that I am a powershell rookie so I gladly welcome any input to help me improve or work more efficiently.  Anyway, I recently used powershell to run the best practice analyzer for DNS on all of our domain controllers.
 The way I went about was pretty tedious and inefficient but still got the job done through a series of one-liners and exported the report to a UNC path as follows:
Enable-PSremoting -Force (I logged into all of the domain controllers individually and ran this before running the one-liners below from my workstation)
New-PSSession -Name <Session Name> -ComputerName <Hostname>
Enter-PSSession -Name <Session Name>
Import-Module bestpractices
Invoke-BPAModel Microsoft/Windows/DNSServer
Get-BPAResult Microsoft/Windows/DNSServer | Select ModelId,Severity,Category,Title,Problem,Impact,Resolution,Compliance,Help | Sort Category | Export-CSV \\server\share\BPA_DNS_SERVERNAME.csv
I'm looking to do this again but for the Directory Services best practice analyzer without having to individually enable remoting on the domain controllers and also provide a lsit of servers for the script to run against. 
Thanks in advance for all your help!

Answer 1

What do you mean by "without having to individually enable remoting "?
You cannot remote without enabling remoting.  You only need to enable remoting once.  It is a configuraiton change.  If you have done it once you do not need to do it again.
Here is how to runfrom a list of DCs.
$sb={
Import-Module bestpractices
Invoke-BPAModel Microsoft/Windows/DNSServer
Get-BPAResult Microsoft/Windows/DNSServer |
Select ModelId,Severity,Category,Title,Problem,Impact,Resolution,Compliance,Help |
Sort Category |
Export-CSV "\\server\share\BPA_DNS_$env:COMPUTERNAME.csv"
Invoke-BPAModel Microsoft/Windows/DirectoryServices
# etc...
ForEach($dc in $listofDCs){
Invoke-Command -ScriptBlock $sb -Computer $dc
¯\_(ツ)_/¯
