如何在远程用户会话上获取映射驱动器

Question

I need to get real mapped drives on remote session, I read remote registry for Path and Name but the label (drive letter) are missing in \\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\MountPoints2

If I read HKCU\\Network I have only the persistent drive (GPP drive with status Replace are missing).

how do I find the path, the name and the label ?

function get-Drives {
        param ( [ValidateNotNullOrEmpty()] $Computername, [ValidateNotNullOrEmpty()] $SID )
        try {
            $Reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('USERS', $computerName)
            $RegKey = $Reg.OpenSubKey("$SID\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\MountPoints2")
            $lecteurs = $RegKey.GetSubKeyNames()
            $lecteurs | ?{$_ -notlike '{*}'} | %{
                $RegKey = $Reg.OpenSubKey("$SID\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\MountPoints2\\$_")
                $_LabelFromReg = $regKey.GetValue('_LabelFromReg')
                if ($_LabelFromReg) {
                    [pscustomobject]@{
                        Name = $_LabelFromReg
                        Label = ''
                        Path = $_ -replace('#','\')
                    }
                }
            }
        } catch {
        }
    }

Answer 1

Getting mapped drives remotely is error-prone. It is far simpler and less trouble to get the list from the user. Here is a short WSH JScript script you can give to users. Users can run this to get a quick dialog box of mapped drives and locations:

// mappedDrives.js

var wshNetwork = new ActiveXObject("WScript.Network");
var networkDrives = wshNetwork.EnumNetworkDrives();
var results = "";
for ( var i = 0; i < networkDrives.length; i += 2 ) {
  var resultLine = networkDrives.Item(i) + " -> " + networkDrives.Item(i + 1);
  if ( results != "" ) {
    results += "\r\n" + resultLine;
  }
  else {
    results = resultLine;
  }
}

var wshShell = new ActiveXObject("WScript.Shell");
if ( results != "" ) {
  wshShell.Popup(results, 0, "Mapped Drives");
}
else {
  wshShell.Popup("No mapped drives detected", 0, "Mapped Drives");
}

Edit: As pointed out by @Alban, this doesn't get the current logged in user's mapped drives, only drives mapped by the computer. I'll leave the answer here as it might be useful for somebody that needs that in the future, but it is obviously not what the OP needed.

Assuming your Helpdesk has access to remote WMI calls you could do this with the Win32_LogicalDisk WMI class. Mapped drives are DriveType 4, so filter for that, and return DeviceID , ProviderName , and VolumeName . Or rename them for ease of reading like:

gwmi -class win32_logicaldisk -Computer $ComputerName | Where{$_.DriveType -eq 4} | select @{n='DriveLetter';e={$_.DeviceID}},VolumeName,@{n='NetworkPath';e={$_.ProviderName}}

Simple enough right? Here's what I got running it against my local computer:

DriveLetter        VolumeName          NetworkPath
-----------        ----------          -----------
X:                 OSDisk              \\localhost\c$\temp

I'm fairly certain that should work against a remote computer for any currently mapped drives.
