WMI and Remote Share Permissions

 Being a contractor I have been on many sites that are just frustrating. 
One of the biggest pains in the butt is having to use workarounds on top of workarounds just to use PowerShell. Currently, I am at a location that has really tight security. It’s one fight after another trying to get things done.
Does anybody else have these head banging on the desk struggles? I cannot do any remoting so I am falling back to using WMI.
Below is an example of the code I am using (very scald down but hopefully you get the idea.

I have reasonable success doing it this way but have run into a problem with share permissions. I could probably put some code together that is a one liner for NTF permissions an have that dumped to a CSV that I pull back but I am struggling with the share permissions. 
Does anybody have any suggestions on how I can go about getting the local share permissions?
My PC:
C: Drive:  Blocked access
PS Ver: 3.0
Running scripts: Disabled (I can get by this by copy and pasting the code into a PS window to load the cmdlets
PS Ver: 2.0
Remoting: Disabled (on most)
Running scripts: Disabled (I can still run WMI commands I just can run something like “Powershell ./Myscript.ps1”
# Example code
$Creds = Get-Credential "Domain\UserName"
$LocalPath = "H:\Data"
# Create an array with one liber commands
$CMD = @()
$CMD += "cmd /C C:\Windows\System32\schtasks.exe /Query /V /FO CSV > C:\ScheduledTasks.csv"
$CMD += "Powershell gwmi Win32_Share | select  | Export-csv C:\Shares.csv -NoTypeInformation" 
# map a drive to each of the servers
$Servers | % {
New-PSDrive -Name $_ -PSProvider FileSystem -Root ('\\' + $_ + '\C$') -Credential $Creds
# Execute WMI commands on remote systems
$CMD | % {
Invoke-WmiMethod Win32_process -name Create -ArgumentList ($_) -ComputerName $Servers -Credential $creds
$Servers | % {   
# Move exported data to personal drive for later manuiplation
Move-Item -Path ($_ + ':\ScheduledTasks.Csv') -Destination ("$LocalPath\$_-ScheduledTasks.csv")
Move-Item -Path ($_ + ':\Shares.Csv') -Destination ("$LocalPath\$_-Shares.csv")
# Remove mapped drive
Remove-PSDrive  $_


Does anybody else have the frustration with an enterprise that has not adopted PS? PS 5.0 brings so much more to the table and with remoting I could accomplish the task at hand in a few hours but I have ben working on different workarounds for a couple weeks now. Hitting one roadblock (like no remoting, or old versions) after another.

  • Do you have any influence? I'd say this company needs a major education into PowerShell, automation and the future of Microsoft Windows administration. It sounds like they are clearly stuck in the past.  Part of the education could be financial. You tell them it takes you X amount of time at $Y/hour to complete a task, but if PowerShell were properly enabled, you could do the same task in Z amount of time and saving them money.

    Otherwise, I'd be brushing off my VBScript files.

    Oh, and if you think the customer would be better off hearing this from an outside expert, I'd be happy to help.
