Rizal,

When you say usb modem, do you mean like a usb cellular card? if so you can perform a check for that particular service to be turned off.

There are two custom checks that you can use, one is a application check and the other is a service check.

thanks,

Tarik

Thank u Tarik for your reply,

Yes Tarik what i mean is usb modem is usb cellular card.

I have tried in my local pc & it is work, but i realize that my client can use different merk usb cellular card, example : user 1 use usb cellular card merk A, user 2 use usb cellular card merk B, user 3use usb cellular card merk C.

If there any method to block different merk of usb cellular card ?

Rizal,

What makes this difficult is that you will have to find all the different types of cards and do some investigating on your end to see what services and applications are used to fire each cell card and then create a policy to turn them off.

Thanks,
