Enabling/Disabling NDIS 5 IM Protocol Bindings

NTDEV
1

I want to allow my application to dynamically enable and disable bindings of my NDIS 5 IM Protocol Driver to all physical network adapters of the system.

So far, I can disable bindings/binding paths using either INetCfgBindingPath::Enable(FALSE) or INetCfgComponentBindings::UnbindFrom(). However, I could not enable the bindings/binding paths using either INetCfgBindingPath::Enable(TRUE) or INetCfgComponentBindings::BindTo().

INetCfgBindingPath::Enable(FALSE) or INetCfgComponentBindings::UnbindFrom().

  1. PtUnbindAdapter and MPHalt are called. - OK
  2. The protocol binding is unchecked in Network Connections Local Area Connection Properties. - OK

INetCfgBindingPath::Enable(TRUE) or INetCfgComponentBindings::BindTo().
3) PtBindAdapter and MPInitialize are NOT called. - NG
4) But the protocol binding is checked in Network Connections Local Area Connection Properties. - OK

Why could be wrong? The notifyobj WDK sample does NOT seem to do anything else before or after enabling the binding paths. Did I miss anything? When I manually check the protocol binding in Network Connections, the virtual network adapter of the NDIS IM is installed and PtBindAdapter and MPInitialize are called.

Sources for BindView are in the WDK. I suggest you start there.
Your application should be running as native code not 32-bit on WOW64 as well. Good Luck,Dave Cattley
