HOWTO: Use Group Policy to disable USB




Sol:-   Just copy and paste the below code into a notepad and save the notepad as .adm file. Eg: usbrestrict.adm





CLASS MACHINE
CATEGORY !!category
 CATEGORY !!categoryname
  POLICY !!policynameusb
   KEYNAME "SYSTEM\CurrentControlSet\Services\USBSTOR"
   EXPLAIN !!explaintextusb
     PART !!labeltextusb DROPDOWNLIST REQUIRED
 
       VALUENAME "Start"
       ITEMLIST
        NAME !!Disabled VALUE NUMERIC 3 DEFAULT
        NAME !!Enabled VALUE NUMERIC 4
       END ITEMLIST
     END PART
   END POLICY
  POLICY !!policynamecd
   KEYNAME "SYSTEM\CurrentControlSet\Services\Cdrom"
   EXPLAIN !!explaintextcd
     PART !!labeltextcd DROPDOWNLIST REQUIRED
 
       VALUENAME "Start"
       ITEMLIST
        NAME !!Disabled VALUE NUMERIC 1 DEFAULT
        NAME !!Enabled VALUE NUMERIC 4
       END ITEMLIST
     END PART
   END POLICY
  POLICY !!policynameflpy
   KEYNAME "SYSTEM\CurrentControlSet\Services\Flpydisk"
   EXPLAIN !!explaintextflpy
     PART !!labeltextflpy DROPDOWNLIST REQUIRED
 
       VALUENAME "Start"
       ITEMLIST
        NAME !!Disabled VALUE NUMERIC 3 DEFAULT
        NAME !!Enabled VALUE NUMERIC 4
       END ITEMLIST
     END PART
   END POLICY
  POLICY !!policynamels120
   KEYNAME "SYSTEM\CurrentControlSet\Services\Sfloppy"
   EXPLAIN !!explaintextls120
     PART !!labeltextls120 DROPDOWNLIST REQUIRED
 
       VALUENAME "Start"
       ITEMLIST
        NAME !!Disabled VALUE NUMERIC 3 DEFAULT
        NAME !!Enabled VALUE NUMERIC 4
       END ITEMLIST
     END PART
   END POLICY
 END CATEGORY
END CATEGORY
 
[strings]
category="Custom Policy Settings"
categoryname="Restrict Drives"
policynameusb="Disable USB"
policynamecd="Disable CD-ROM"
policynameflpy="Disable Floppy"
policynamels120="Disable High Capacity Floppy"
explaintextusb="Disables the computers USB ports by disabling the usbstor.sys driver"
explaintextcd="Disables the computers CD-ROM Drive by disabling the cdrom.sys driver"
explaintextflpy="Disables the computers Floppy Drive by disabling the flpydisk.sys driver"
explaintextls120="Disables the computers High Capacity Floppy Drive by disabling the sfloppy.sys driver"
labeltextusb="Disable USB Ports"
labeltextcd="Disable CD-ROM Drive"
labeltextflpy="Disable Floppy Drive"
labeltextls120="Disable High Capacity Floppy Drive"
Enabled="Enabled"
Disabled="Disabled"



Now open gpmc.msc in domain controller 

start --> Run --> gpmc.msc --->computer configuration ---> right click on Add/remove templates 

click on Add and browse for the *.adm file which we have saved in our previous step  eg: usbrestrict.adm

select usb.adm and click ok

Now, we need to update the group policy

Start --> Run --->gpupdate /force

That is it we are done with the blocking of USB drives in domain environment using group policy
