vbscript to enable network connections

I have been using a vbscript in XP to enable/disable network connections that
uses the NAMESPACE method to examine the network control panel ( see code
snippet). However in Vista the network control panel and list of network
devices does not appear to be in the NAMESPACE method any more. The "Network
and Sharing Center" control panel replaced the "Network Connections" in Vista
and the list of connections seems to have disappeared from the namespace
method information. I am sure I am overlooking something simple. Anybody?
Here is a snippet of what I am doing on XP
---snippet-----------------------------------------------------------------------------
Const ssfCONTROLS = 3

sConnectionName = "Local Area Connection"

sEnableVerb = "En&able"
sDisableVerb = "Disa&ble"

set shellApp = createobject("shell.application")
set oControlPanel = shellApp.Namespace(ssfCONTROLS)

set oNetConnections = nothing
for each folderitem in oControlPanel.items
if folderitem.name = "Network Connections" then
set oNetConnections = folderitem.getfolder: exit for
end if
next

if oNetConnections is nothing then
msgbox "Couldn't find 'Network Connections' folder"
wscript.quit
end if

Thanks. This seems to be the information I need. However, I have tried
running the VBscript and it does not seem to really enable the network card.
I am running an evaluation copy build 5744 of Windows Vista Ultimate and I
receive a error code 740 from the line "objitem.Enable" from Figure 4 of the
"Hey Scripting Guy" article:
-------------------------------------------------
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")
Set colItems = objWMIService.ExecQuery( _
"SELECT * FROM Win32_NetworkAdapter Where NetEnabled = 'False'")

For Each objItem in colItems
Wscript.Echo "Name: " & objItem.Name
Wscript.Echo "Description: " & objItem.Description
objItem.Enable
Wscript.Echo
Next
 
Same error code seen in Vista RTM. 740 might be related to UAC / Elevation
issues, I guess.

I don't get an error with a standard CMD prompt, or by running the script
directly. But it doesn't do anything.

However, if I run it from an elevated CMD prompt (ie one started with Run
As Administrator), the script works.

The script terminates silently by default. You need to modify the code
slightly in order to see the error code.

Change the following line:

- - -
objItem.Enable
- - -

to

- - -
rtn=objItem.Enable
msgbox rtn
- - -

or

- - -
msgbox objItem.Enable
- - -

Nice! Then it's an UAC/elevation issue as I thought.

I'd say a bit of both. Changing network properties is a privileged
operation, and therefore the script should only work with elevated
privileges. OTOH, you don't get a UAC prompt when running the script, and
you ought to (but I can see how implementing it could be an absolute
nightmare!).
 
The VBscript really should prompt.

Certainly agree. BTW, here is some documentation I found at MSDN:

I would have to agree. The VBscript really should prompt. I am sure many
administrators have scripted "privileged" operation that are all going to
fail without warning when run on Vista because the default way to run a
VBscript is to double-click. It appears to me this behavior would encourage
administrators that have written these types of script to assist their user
population might begin to simple turn UAC off on the computers that they
administer, so that end users could run these types of scripts. Does anyone
from Microsoft monitor these newgroup? What say you?
