Routine Description:
|

|
|
|||
|
This function obtains a overriding priority value from the registry for a given
|
|||
|
transport.
|
|||
|
|
|||
|
The priority of a transport controls the order in which connections are accepted. It is
|
|||
|
sometimes useful for a customer to control which transport is used first in the redirector.
|
|||
|
|
|||
|
The priority is usually determined by the order of the transports in the binding list. With
|
|||
|
the new Connections UI model for network setup, it will no longer be possible to adjust
|
|||
|
the order of the bindings in the binding list. Thus, another mechanism is needed when the
|
|||
|
user wants to override the priority assigned to a given binding.

|||
|
|
|||
|
Arguments:
|
|||
|
|

|
pTransportName - pointer to UNICODE_STRING descriptor for transport string, for example
|

|
"\Device\Netbt_tcpip_{guid}"

Routine Description:
|
|||
|
|
|||
|
This routine should not be part of rdr. It has been introduced into this
|
|||
|
component to overcome current limitations in NetBt. The NetBt transport
|
|||
|
exposes two kinds of devices -- the traditional NetBt device and the
|
|||
|
new non Netbios device which make use of the NetBt framing code without the
|
|||
|
name resolution aspects of it. The current implementation in NetBt exposes
|
|||
|
the former devices on a per adapter basis while the second category of device
|
|||
|
is exposed on a global basis ( one for all the adapters ). This poses
|
|||
|
problems in disabling/enabling srv on a given adapter.
|
|||
|
|
|||
|
The correct solution is to expose the second category of devices on a per
|
|||
|
adapter basis. Till it is done this workaround is reqd. With this workaround
|
|||
|
whenever the server is notified of any changes to the binding string it turns
|
|||
|
around and notifies the NetBt transport about these changes.
|
|||
|
|
|||
|
This routine is based upon the following assumptions ...
|
|||
|
|
|||
|
1) The notification from TDI is not done at raised IRQL.
|
|||
|
|
|||
|
2) The thread on which this notification occurs has enough access rights.
|
|||
|
|
|||
|
3) The notification to NetBt is done asynchronously with srv's reaction
|
|||
|
to the change. The srv handles the PNP notification by passing it off to
|
|||
|
user mode and have it come through the server service.
|
|||
|
|
|||
|
Arguments:
|
|||
|
|
|||
|
PNPOpcode - the PNP opcode
|
|||
|
|
|||
|
DeviceName - the transport for which this opcode is intended
|
|||
|
|
|||
|
MultiSZBindList - the binding list

|||
