--------------------------------------------------------------------------------

Dear All

We have win2k3 server and all our workstations are windows xp. we want to prevent users copying any data to external storage devices like / Floopy / USB / cd writers / external cd writer(USB) interface etc.

We used the following registry key to write protect the same.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies]
"WriteProtect"=dword:00000001

after editing this , i am not able to copy any files to USB pen drive, but still i am able to burn cd's using external CD writers.

How do I prevent for all external storage device?
How do I deploy this registry key through group poilcy?

Pls. help me

Regards
Sakthi
