PowerShell Issue regarding entering a PS Session and setting permissions - powershell

Question

I am currently making a script to create a folder which then creates an AD group and links them together. I then connect to our server in the data centre to set the permissions.
To do this I need to enter a PSSession and find the folder and set the permissions. Unfortunately, it's not working. Any help would be appreciated.
Script
#Get ADM Credentials
$Cred = Get-Credential
# PowerShell's New-Item creates a folder
$Name = Read-Host "What is the name of the folder?"
$Location = Read-Host "What is the folder path? i.e B:\Collaboration\"
New-Item -Path $Location -Name $Name -ItemType "directory"
#Invoke-Item $Location
# Powershell creates an AD group
$Groupname = Read-Host "What is the group name? i.e. SS COLLABORATION BEN"
New-ADGroup -path "OU=StorSimple Centralisation Groups,OU=Groups,OU=Northgate PLC,DC=northgatevehiclehire,DC=net" -Name $Groupname -GroupCategory Security -GroupScope Global -DisplayName $Groupname -Description "Access to $Location" -Credential $cred
#Connect to StudFS01
$Folderpath = Read-Host "What is the path of the folder in StudFS e drive? i.e. Vehicle Sales\TOM Information"
Enter-PSSession -ComputerName Studfs01 -Credential $Cred
Start-Sleep -Seconds 10
Set-Location -Path E:\CentralisedData\Data\$folderpath
#Set Permissions
$rule=new-object System.Security.AccessControl.FileSystemAccessRule ("northgatevehiclehire.net\Domain Admins","FullControl","Allow")
$rule2=new-object System.Security.AccessControl.FileSystemAccessRule ("northgatevehiclehire.net\StorSimple Centralisation Administrators","FullControl","Allow")
$rule3=new-object System.Security.AccessControl.FileSystemAccessRule ("$Groupname","Modify","Allow")
$acl = Get-ACL E:\CentralisedData\Data\$folderpath
$acl.SetAccessRule($rule,$rule2,$rule3)
Set-ACL -Path E:\CentralisedData\Data\$folderpath -AclObject $acl
Error Im getting is below
Set-Location : Cannot find drive. A drive with the name 'E' does not exist.

Answer 1

Instead of Enter-PSSession which is meant for interactive use, you need to establish a new PSSession and then use Invoke-Command against it. Something like this:
$PSSession = New-PSSession -ComputerName Studfs01 -Credential $Cred
Invoke-Command -Session $PSSession -ScriptBlock {
<CODE TO EXECUTE ON REMOTE SYSTEM HERE>
}
If you need to pass parameters/variables, you have two choices. The easiest (in newer versions of PowerShell) is the using statement like this:
$PSSession = New-PSSession -ComputerName Studfs01 -Credential $Cred
Invoke-Command -Session $PSSession -ScriptBlock {
Set-Location -Path E:\CentralisedData\Data\$using:Folderpath
}
Another option is to pass your arguments with -ArgumentList and use Param() in the script block like this:
$PSSession = New-PSSession -ComputerName Studfs01 -Credential $Cred
Invoke-Command -Session $PSSession -ArgumentList $Folderpath -ScriptBlock {
Param($Folderpath)
Set-Location -Path E:\CentralisedData\Data\$Folderpath
}
