To configure a remote machine (named machinename) from the command-line in XP as a domain admin.

sc \\machinename config USBSTOR start= disabled

to re-enable

sc \\machinename config USBSTOR start= demand

To view the current configuration of the USBSTOR service

sc \\machinename qc USBSTOR

Use a software to enable/disable USB ports is very easy, it is Disable USB Ports Tool - disable or block USB storage device, set USB ports to read only and it can control more computers in 1 network.

Enable/Disable USB access in local/remote computer using a smart way...

Use IntelliAdmin Remote USB disabler. Hope this will help.

at my workplace we also use a software to block/allow/read only devices and ports, it's called Endpoint Protector 4

There are several ways to do so.I'm mentionaing a few :
1) disabling via device manager
2) through bios commands
3) uninstalling the drivers :RECOMMENDED : this is the best way as no advanced user can enable rather change the settings without your permission as with other options a geek as me can possibly tweak the system and egt the USB access.
4) by edting registry using regedit command.


Hope it helps you.
