Powershell Equivalent of NET USE /DELETE?

Question

I've been searching through the PowerShell documentation to find a way to clean up my client session connections.

I can use Get-SMBConnection to list open connections but there is no corresponding delete/close-Connection

I can use the NET USE /DELETE command interactively - is there a PowerShell equivalent?

Answer 1

It's a two-step process in PowerShell.

1. Remove-SMBMapping
2. Remove-PSDrive

It looks like the original link (https://blogs.msmvps.com/russel/tag/remove-psdrive/) for a bit of code is no longer producing the expected result (i.e., doesn't work). Here's another link to a problem that was posted on GitHub that had the PowerShell code: https://github.com/PowerShell/PowerShell/issues/7829

BE CAREFUL! The code will remove ALL mapped drives! It doesn't take any parameters!

I'll repost that code below:

<#
.SYNOPSIS
Unmaps network drives
.DESCRIPTION
Unmapdrives removes all currently mapped network drives. It's smart enough to 
remove drives mapped with "net use", "New-SmbMapping" and "New-PSDrive". This 
cmdlet accepts no parameters and assumes -Force for all unmappings. 

.EXAMPLE
UnMapDrives 
Unmaps all currently mapped network drives

# Build a dynamic list of currently mapped drives
$DriveList = Get-WMIObject Win32_LogicalDisk `
     | Where-Object { $_.DriveType -eq 4 }

# Don't bother running this if we don't have any mapped drives
 if ($DriveList) { 
    $SmbDriveList = $DriveList.DeviceID
 } else {
    Write-Host "No mapped drives found"
    Return
}

Write-host "Unmapping drive: " -NoNewLine
Write-Host $SmbDriveList
Write-Host " "

Foreach ($drive in $SmbDriveList) {
    $psDrive = $drive -replace ":" #remove unwanted colon from PSDrive name
    Remove-SmbMapping -LocalPath $Drive -Force -UpdateProfile
    If ( (Get-PSDrive -Name $psDrive) 2>$Null ) {
       Remove-PSDrive -Name $psDrive -Force
    }
}
Write-Host " "

# Report back all FileSystem drives to confirm that only local drives are present. 
Get-PSDrive -PSProvider FileSystem`

It wouldn't take much to make this into a function that does take a parameter (maybe a single drive letter, or a list of drive letters, to remove). Until then, use this at your own risk!!!
