Hi,

I know that MS had provided a document to guid how to hid a device from
device manager within a bus driver or filter, but now I need to hid a
network device, the “Irp” process has been packed up by OS and any way can
achive the hiding within an IM driver as well?

Thanks

Are you trying to hide an adapter from the UI?
Is this an adapter created by your driver or one that is in the system that
you want to hide away?

Have you considered what NCF_HIDDEN might do for you if applied to the
adapter’s Characteristics property?

Good Luck,

Hi Dave,

I want to hide the adapter exist in system, not created by me, and the
NCF_HIDDEN needs reboot system? I want to hide the NIC without reboot.
Actually I’m developing Teaming driver and looks some vendor’s driver could
hide their NIC from device manager and network local area without restart
OS.

Yes, Some driver been hide, we can’t find it in device manager, But it can be find in “network connect” still.
Why do you want to do ?

I want to hid the teamed network devices and show the combinaed Teaming
virtual miniport driver only, so the users can only configure the virtual
miniport driver.

I think it is a bad idea to hide these things from user.

You can hide the teamed network adapter by editing their registry entry. There is registry key “Characteristics” for every adapter typically under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4D36E972-E325-11CE-BFC1-08002bE10318}.
Value generally is 0x84. Make it to 0x8c and disable/enable adapter. It will go without asking for reboot.

Hi Virendra,

Thank you a lots. I’ve tried edit the registry key and reboot os to hide
NIC before, now I’ll try just disable/enable it to avoid system reboot.
