What needs to exist in a PowerShell script to assure Get-WMIObject works?

Hello Expert,

My goal is to export the desktop computer names from active directory, place the output into a text file and loop the names through the script to determine the administrator accounts on over 700 desktops.  When I tested the script I received an error:

"Get-WmiObject: The RPC is unavailable
     $AllLocalAccounts = Get-WmiObject -Class ...
   + CategoryInfo: Invalid Operation: (:) ... "

What is the script missing the 'AllLocalAccounts' variable? What is the best syntax?
Set-StrictMode -Version Latest
Set-ExecutionPolicy remotesigned -Force
import-module activedirectory

Get-ADComputer -Filter '*' -SearchBase "OU=Computers,DC=company,DC=com" -Properties Name | Select Name |  Out-File C:\Scripts\DesktopAccounts.txt


Param
(
	[Parameter(Position=0,Mandatory=$false)]
	[ValidateNotNullorEmpty()]
	[Alias('cn')][String[]]$ComputerName=(get-content c:\Scripts\DesktopAccounts.txt),
	[Parameter(Position=1,Mandatory=$false)]
	[Alias('un')][String[]]$AccountName,
	[Parameter(Position=2,Mandatory=$false)]
	[Alias('cred')][System.Management.Automation.PsCredential]$Credential
)
	
$Obj = @()

Foreach ($Computer in $ComputerName)
{
	If($Credential)
	{
		$AllLocalAccounts = Get-WmiObject -Class Win32_UserAccount -Namespace "root\cimv2" `
		-Filter "LocalAccount='$True'" -ComputerName $Computer -Credential $Credential -ErrorAction Stop
	}
	else
	{
		$AllLocalAccounts = Get-WmiObject -Class Win32_UserAccount -Namespace "root\cimv2" `
		-Filter "LocalAccount='$True'" -ComputerName $Computer -ErrorAction Stop
	}
	
	Foreach($LocalAccount in $AllLocalAccounts)
	{
		
        Set-ExecutionPolicy remotesigned -Force
        Import-Module activedirectory

        Set-StrictMode -Version Latest

        $Object = New-Object -TypeName PSObject
		
		$Object|Add-Member -MemberType NoteProperty -Name "User Name" -Value $LocalAccount.Name
		$Object|Add-Member -MemberType NoteProperty -Name "Full Name" -Value $LocalAccount.FullName
		$Object|Add-Member -MemberType NoteProperty -Name "Logon Account Caption" -Value $LocalAccount.Caption
      	$Object|Add-Member -MemberType NoteProperty -Name "Disabled" -Value $LocalAccount.Disabled

		$Object|Add-Member -MemberType NoteProperty -Name "Domain" -Value $LocalAccount.Domain
		$Object|Add-Member -MemberType NoteProperty -Name "Description" -Value $LocalAccount.Description
		
		$Obj+=$Object
	}
	
	If($AccountName)
	{
		Foreach($Account in $AccountName)
		{
		    $Obj| Where-Object{$psitem.Name -like "$Account"} 
		}
	}
	else
	{
		    $Obj | Export-csv c:\Scripts\DesktopAccounts.csv
	}
}
