MTP protocol

[King X13]

On my network i have Mass storage devices disabled through the registry because people were bringing in there MP3 players and PSPs and filling up my servers with there music.

But now i see a few users using devices which use MTP and these devices do not come up as mass storage i have read and through seeing that my blocks do not disable them.

Anyone know how i can disable these devices or at least point me at its registry locations? thanks guys.

If you uninstall WMP10 or higher and delete the files you will remove the MTP drivers.

Start>run>Services.msc

Look for the service:

portable device enumerator service

Description: Enforces Group Policy for removable mass-storage devices. Enables applicaitons such as WMP and Image Import Wizard to transfer and sync content using removable mass-storage devices.

That should stop them. But if i am not mistaken that will also stop USB Thumb drives.

i thought about that for about .1 seconds lol as i have 800 systems on my network.

As for Makaveli213, ill give this a shot but from what i read it doesnt get labeled a "mass storage device" so anything that would normally disable mass storage doesnt work for MTP devices.

Then your best option will be a GPO.

That looks interesting. But that is Vista only.Maybe figure out how to add a entry to the GPO to block them.

From what i gathered in my searches for answers. Most MTP Devices are recognized as a USB device. Maybe not Mass Storage but a USB Device. So check int he Services are as well for a way to disable them. If you wish.

the keyboard and mouse to these systems are USB, do you think doing that would kill them also?

 

[KSoD]

Not sure. I have not tested it on my system at all as i dont want to have that stuff disabled. So it might be better to try GPO first.

You may be forced to just put a cap on their storage space and let it go.
