Disable Bluetooth Radio on multiple laptops?

Hi all
I know how to disable the Bluetooth Radio on a Dell laptop, but to resolve an iPass Remote Access / bindop.exe issue, we need the ability to disable the Bluetooth Radio on 500+ Dell Latitude (D410/20/30) laptops (long story!).
I have searched the web for ideas and some have attempted registry changes but didn't work. Has anyone else tried to disable the Bluetooth Radio on multiple laptops via the registry/scripting/anything else please?
Thanks Scott

Erm, stop the "Bluetooth Service" service.
Don't have a Dell machine to hand right now, but to acheive it on HP Business Notebooks;

net stop "Bluetooth Service"

Depending on the name Dell use for the bluetooth service, you would obviously just need to change the bit inside the " "'s.

Alternatively, if you use AD, create a GP to apply to the machines, and configure the service to be disabled, which will also prevent it running.

Thanks James, quite right.    Embarrassed
Forgot to mention that we'd prefer not to disable the service, because we want the users to be able to use "Enable Bluetooth" if needed.
Is there anyway to not have to disable the Bluetooth service, but just disable the Bluetooth Radio please?
Thanks
Scott

PJ, you had a chance to test yet?  Any joy? 
I stopped the only started Bluetooth service called "Bluetooth Support Service" on a Dell D420 laptop but makes no change to the network card status or BT system tray icon (still connected). 
So ideally, we need to be able to disable the Bluetooth network card altogether.  Is this possible please?
Cheers
Scott

Re: Disable Bluetooth Radio on multiple laptops?

Yeah, my bad!
Having read up on the subject a little more, it transpires that the Bluetooth Service is actually just a helper service, "Handles installation and removal of Bluetooth devices."
Have you thought of removing bluetooth from the startup list?

Re: Disable Bluetooth Radio on multiple laptops?

Hi James - it's transpired that we need to remove the Bluetooth NIC completely in order to allow bindop.exe to work its magic on the LAN NIC (long story!).  I found a solution so please read on for anyone who's interested...
Testing has confirmed that the following automated methods to disable Bluetooth (BT) do not work / are not suitable:-
1) Killing the TosOBEX.exe and/or TosBtProc.exe processes running in Task Manager do not disable the BT NIC.
2) Disabling any of the BT Services does not disable the BT NIC.
3) No appropriate command line arguments with BtSwInst.msi (master BT Installation file).
4) Regmon confirmed there were 10s if not hundreds of registry keys that were involved when the BT NIC is manually disabled, so would be finding a needle in a haystack!
5) We could disable the BT BIOS setting, but Toshiba do not supply a utility to manage multiple BIOSes and the Dell Client Configuration Utility (DCCU) is limited on managing multiple machines also.
6) There may be a way to move the NIC to top of list in the Network "Adapter Bindings" (Control Panel --> Network Connections --> Advanced --> Advanced Settings), but none found as yet.
7) Utility called "ToggleNIC" created by a 3rd party individual works but need to know exact name of NIC to be disabled, e.g. C:\>toggleNIC.exe "Bluetooth" disable may work on one machine but not on a machine if the BT NIC is named "Local Area Connection #3", for example.
*** SOLUTION ***
Microsoft's own DEVCON.exe utility disables any NIC including Bluetooth http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q311272. ; For example:-
C:\>devcon.exe disable *bluetooth*
…searches for all NICs containing "bluetooth" and disables them.  14 instances found on a Dell D420.
However, if at a later date we need to fully re-enable the BT NIC, the following command line must be executed 3 times (on a Dell D420 at least anyway):-
C:\>devcon.exe enable *bluetooth*
NB: The first time this command line is executed, 2 instances of "bluetooth" are re-enabled.  The second time this command line is executed, 13 instances of "bluetooth" are re-enabled.  Finally, the third time this command line is executed, 14 instances of "bluetooth" are re-enabled, then the BT NIC re-appears in Control Panel --> Network Connections.
HTH
