Hi all,

I need a power shell script to programmatically check if a given workstation has mapped drives using a certain user. I know that mapped network drive settings are stored into HKCU\Network\mapped drive letter} But I don't know if the mughty power shell offers some other way to accomplish this task.

Hi,

It seems like that if we mapped a drive to the computer, then we could achieve all mapped drives by Gwmi -computername.

But if we map drives to users, them we should find out those drives based on reading the key: HKCU:\Network\

I would like suggest you refer to the below link to use Remote Registry PowerShell Module:

http://blogs.microsoft.co.il/blogs/scriptfanatic/archive/2010/01/10/remote-registry-powershell-module.aspx

In addition, here is a VBscript for you, we could also use it with powershell:

Hope this helps.

Best Regards,

I'm trying to build a powershell script that enumerate mapped network drives on a remote machine. I've to browse the remote registry HKEY_USERS and, if exists, I've to loop into the "Network" subkey here is my script:

$srv='pc_to_scan'
$type = [Microsoft.Win32.RegistryHive]::Users
$regKey = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($type, $Srv)
$key = "Network"
foreach ($valueName in $regKey.GetSubKeyNames())
{
$regKey2 = $regKey.OpenSubKey($key)
foreach ($valueName2 in $regKey2.GetSubKeyNames())
{
echo $valueName2
}
}

but the script fails telling:

You cannot call a method on a null-valued expression.
At line:9 char:52

foreach ($valueName2 in $regKey2.GetSubKeyNames <<<< ())
+ CategoryInfo : InvalidOperation: (GetSubKeyNames:String) [], RuntimeException
+ FullyQualifiedErrorId : InvokeMethodOnNull

gwmi win32_logicaldisk -Filter "drivetype='4'"

tack on the -computername and it works remotely

Andrea,

The following will work if Powershell Remoting is enabled on the remote machines ( Enable-PSRemoting )

Function Get-MapDriveUsername {             
             
      Param(            
        $computer = $env:COMPUTERNAME,            
        $reg = "hkcu:\network",            
        $username = "Contoso\SP_Admin"            
        )            
             
       $computer | %{            
           $drives = ICM -ComputerName $_ {             
              Param($reg)             
              dir $reg            
                } -ArgumentList $reg             
           $comp = $_            
          $obj = New-Object psobject             
          if($drives -ne $null) {            
             $drives | %{            
             $driveletter = $_.name.split("\")[-1]            
             foreach($i in $driveletter) {            
                $drive = (Get-ItemProperty (Join-Path $reg $i))            
                if($drive.username -like $username) {            
                    $obj | Add-Member Noteproperty Computer $comp            
                    $obj | Add-Member Noteproperty Drive $drive.PSChildName

     }

   }            
  }            
   Write-Output $obj            
 }

Kazun,

Not sure I understand....what other credentials are needed?

Following command should work for you:

Gwmi Win32_LogicalDisk -filter "DriveType = 4" -Comp $strComputer

Hope this helps...!!!
