WMI Read Registry Remotely...

[GregThompson]

Ok, so I wrote this script, it works on some machines in my company, but not others, wtf? I don't get how the remote registry, which is available on all our machines I can get to thru regedit, but when I run this file, some report back, others error out??? Any help much appreciated.

Const HKEY_LOCAL_MACHINE = &H80000002

strComputer = "el044552"

Set objRegistry = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & _ 
    strComputer & "\root\default:StdRegProv")
 
strKeyPath = "SYSTEM\Setup"
strValueName = "OEMDuplicatorString"
objRegistry.GetStringValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,strValue

If IsNull(strValue) Then
    Wscript.Echo "The registry key does not exist."
Else
    Wscript.Echo strValue
End If

Here is the problem, you aren't using AutoIt. Ptrex will tell you to add in a COM error handler.

Const $HKEY_LOCAL_MACHINE = "&H80000002"

$strComputer = "el044552"

Dim $objRegistry = ObjGet("winmgmts:{impersonationLevel=impersonate}!\\" & $strComputer & "\root\default:StdRegProv")

$strKeyPath = "SYSTEM\Setup"
$strValueName = "OEMDuplicatorString"
$objRegistry.GetStringValue($HKEY_LOCAL_MACHINE,$strKeyPath,$strValueName,$strValue)

If $strValue = "" Then
ConsoleWrite( "The registry key does not exist.")
Else
ConsoleWrite( $strValue)
EndIf

EDIT: Also the Autoit Reg* functions do work remotely

It is possible to access remote registries by using a keyname in the form "\\computername\keyname". To use this feature you must have the correct access rights on NT/2000/XP/2003, or if you are using a 9x based OS the remote PC must have the remote registry service installed first (See Microsoft Knowledge Base Article - 141460).
