Hi,

You can use:

$strMachineName = '.'
$objReg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $strMachineName)
$objRegKey= $objReg.OpenSubKey("SYSTEM\\SOFTWARE\MQUEST\\ScriptEngine\\Program\\PrimaryScriptServer" )
$objRegkey.GetValueNames()

Hope it helps.

Hi,
Please have a read of these articles

$objRegKey= $objReg.OpenSubKey("SOFTWARE\\MQUEST\\ScriptEngine\\Program\\PrimaryScriptServer" )
one slash is missed. And remove SYSTEM in key path.

this fine works for me. Are you sure that this key exist in HKLM\SOFTWARE\MQUEST\ScriptEngine\Program\PrimaryScriptServer on MURBAMEXV004?

i have check that machine even in 005 the key exist...I can pull if from this VBS..

Set oReg = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\default:StdRegProv")
strKeyPath = "SOFTWARE\MQUEST\ScriptEngine\Program\"
strValueName = "PrimaryScriptServer"
oReg.GetStringValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,strValue
verFn = StrValue

I understand. In your VBS code is shown that SOFTWARE\MQUEST\ScriptEngine\Program\ is Key path. However PrimaryScriptServer is not a key, but value. And code above retrives only names. If you want to get particular name value, you can use :

$strMachineName = 'MURBAMEXV004'
$objReg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $strMachineName)
$objRegKey= $objReg.OpenSubKey("SOFTWARE\\MQUEST\\ScriptEngine\\Program" )
$objRegKey.GetValue("PrimaryScriptServer")

If I understand correctly, this code should work. And after this you can read data for values:
$strMachineName = 'MURBAMEXV004'
$objReg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $strMachineName)
$objRegKey= $objReg.OpenSubKey("SOFTWARE\\MQUEST\\ScriptEngine\\Program" )
"PrimaryScriptServer", "SecondaryScriptServer", "Server1", "Server2" | %{
"Data for value " + $_
$objRegKey.GetValue("$_")
}
or place values to variable:
$values = "PrimaryScriptServer", "SecondaryScriptServer", "Server1", "Server2"

and query:
$values | %{
"Data for value " + $_
$objRegKey.GetValue("$_")
}

Why make it so hard when it can be done so easy :-)

reg query "\\<computername>\HKLM\SOFTWARE\MQUEST\ScriptEngine\Program\PrimaryScriptServer

Check the "reg query /?" command for details

To get info from several machines this command can be used:
for %i in (server1,server2,server3) do reg query "\\%i\HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v SessionPoolSize

This is an example to get/query a given registry key value for all servers in a Terminal Server farm (run from a TS):
for /f "skip=3 delims=* " %i in ('qfarm /servers') do @echo --------------- %i --------------------- & reg query "\\%i\HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v SessionPoolSize

Have fun,
