    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 " + $_
    $objRegKey.GetValue("$_")
    }

    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.

    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

    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,

    So reg query \\computername\hklm:\.." is erroring out?  Saying invalid computer name.  Is there no way to use get-itemproperty remotely?

    Cheers.

    The command should work as long as you can ping your servername.

    You can also use server IP like this

    \\10.10.10.20\HKLM\Software...

    In your example above you have ":" after HKLM .. that is incorrect I believe

    /Tord

    /Tord

    Yeah, the ":" after HKLM is powershell-ese for "use this other provider" - without that a registry path would be indistinguishable from a relative or absolute path or UNC.

    "reg", or, less ambiguously, "reg.exe" needs no such distinction as registry paths are the only things it deals with.

    Ah yes!  I removed the ":" and it worked.  I also found that I can use a variable for \\<machine name>.  This way I can query several machines at same time.

    Thx everyone!
