I am in a process of writing the Kernel mode Network mini redirector. I am
extending the sample nulmrx from IFS Kit to achieve the same.
For the complete process I have the NP-DLL and Helper service (for protocol
stuff) in user mode and my mini redirector in kernel mode.
I have almost completed the cycle for making the connection from the GUI
(for taking the connection parameter and drive letter) to NP DLL
NPAddConnection3() function to mini redirector and then back to user mode
helper service for actually making the connection (using invert call
mechanism). Once this complete cycle is done I am getting the Drive mounted
in explorer but it shows disconnected status.
Later when I debug this issue with windbg NP DLL fires the NPGetConnection
IOCTL in my redirector which after receiving the parameter goes to helper
service for connection and then we return from connection function from
redirector after this NP DLL mount the driver letter.
Just after this process complete RDBSS call NulMRxCreateSrvCall() and the
connection name I receive here is \Desktop.ini. RDBSS later continues to
call NulMRxSrvCallWinnerNotify() and NulMRxCreateVNetRoot() and in all case
the pNetRootName is \Desktop.ini.
But at the end my driver is disconnected.
Can any one please tell me if I need to do some thing to my unc path instead
of \Desktop.ini in the srv call and netroot call.
I appreciate all the help.
Thanks,

Thanks for the reply I am badly stuck with this issue.
Sorry it was NPAddConnection3() which is called from NP DLL and with
IOCTL_ADDCONNECTION
There is a following line of code in CreateConnection()
if ( ! BooleanFlagOn(RxContext->Flags, RX_CONTEXT_FLAG_WAIT) )
{
// just post right now
*PostToFsp = TRUE;
return STATUS_PENDING;
}
The *PostToFsp line sets RxContext->PostRequest to true it enters this code
block, and the I/O never completes.
If I Comment out this part of code and complete the connection NP DLL get
WN_SUCCESS for the add connection IOCTL and DefineDosDevice() get call in
NP DLL which mounts the drive, but disconnected.
I got a feeling the Prefix table is not filled with my unc path is RDBSS
fills this table or we have to this explicitly in our redirector.
Thanks

Subject: Re:[ntfsd] Network Redirector
So do I need to fill the prefix table or RDBSS will do that. When I try to fetch LookupName(my UNC path of connection) it is not there in the prefix table.
It will be of great help if you can put some more light on this.
Thanks Imran

It’s up to you to verify LookupName. You can implement you own mechanism and
check it for fetching name during IOCTL_GET_CONNECTION.

Hi,
In NPGetConnection my DeviceIOControl() returm with error 67 (Bad Network Name), and in my redirector in switch case of IOCTL_GETCONNECTION it return the STATUS_BAD_NETWORK_NAME as the call in my redirector for prefix table

Thanks for the reply I am badly stuck with this issue.
Sorry it was NPAddConnection3() which is called from NP DLL and with IOCTL_ADDCONNECTION
There is a following line of code in CreateConnection()
if ( ! BooleanFlagOn(RxContext->Flags, RX_CONTEXT_FLAG_WAIT) ) { // just post right now *PostToFsp = TRUE; return STATUS_PENDING; }
The *PostToFsp line sets RxContext->PostRequest to true it enters this code block, and the I/O never completes.
If I Comment out this part of code and complete the connection NP DLL get WN_SUCCESS for the add connection IOCTL and DefineDosDevice() get call in NP DLL which mounts the drive, but disconnected.
I got a feeling the Prefix table is not filled with my unc path is RDBSS fills this table or we have to this explicitly in our redirector.
Thanks Imran

What Status did you NP DLL return? I got same disconnected problem some time
ago, and it was concerning to NPGetConnection function. “Imran Kazi” ???/??? ? ??? ???: news:xxxxx@ntfsd… Hello,
I am in a process of writing the Kernel mode Network mini redirector. I am extending the sample nulmrx from IFS Kit to achieve the same. For the complete process I have the NP-DLL and Helper service (for protocol stuff) in user mode and my mini redirector in kernel mode.
I have almost completed the cycle for making the connection from the GUI (for taking the connection parameter and drive letter) to NP DLL NPAddConnection3() function to mini redirector and then back to user mode helper service for actually making the connection (using invert call mechanism). Once this complete cycle is done I am getting the Drive mounted in explorer but it shows disconnected status.
Later when I debug this issue with windbg NP DLL fires the NPGetConnection IOCTL in my redirector which after receiving the parameter goes to helper service for connection and then we return from connection function from redirector after this NP DLL mount the driver letter.
Just after this process complete RDBSS call NulMRxCreateSrvCall() and the connection name I receive here is \Desktop.ini. RDBSS later continues to call NulMRxSrvCallWinnerNotify() and NulMRxCreateVNetRoot() and in all case the pNetRootName is \Desktop.ini.
But at the end my driver is disconnected.
Can any one please tell me if I need to do some thing to my unc path instead
of \Desktop.ini in the srv call and netroot call.
I appreciate all the help.
