Routine Description:
|
|
|
|
This routine handles all the device FCB related FSCTL's in the mini rdr
|
|
|
|
Arguments:
|
|
|
|
RxContext - Describes the Fsctl and Context.
|
|
|
|
Return Value:
|
|
|
|
STATUS_SUCCESS -- the Startup sequence was successfully completed.
|
|
|
|
any other value indicates the appropriate error in the startup sequence.
|
|
|
|
Notes:
|
|
|
|
There are some dependencies between the browser service and the redirector
|
|
service that have implications regarding the sequence of actions for starting
|
|
the mini redirector.
|
|
|
|
The current LANMAN workstation service opens the LANMAN and BROWSER device
|
|
objects, issues the LMR_START and LMDR_START IOCTL's and subsequently
|
|
issues the BIND_TO_TRANSPORT IOCTL.
|
|
|
|
In the multiple mini rdr/wrapper design for PNP the TDI registration is done
|
|
at wrapper load time and the mini rdrs are notified of the existing transports
|
|
at START time ( LMR_START ). Since there are no BIND_TO_TRANSPORT IOCTL in
|
|
PNP the rdr is responsible for issuing the BIND_TO_TRANSPORT IOCTL to the \
|
|
browser.
|
|
|
|
This should be changed by having the BROWSER gave its own TDI registration
|
|
but till then the invocatioon of RxStartMiniRdr routine must be deferred to
|
|
FSCTL_LMR_BIND_TO_TRANSPORT so that the browser has been initialized correctly.
|
|
|
|
The reason for this convoluted change is that there is a code freeze for checking
|
|
in changes to the workstation service/browser.
