network redirector device types

NTFSD
1

I am writing a network redirector for Windows 2000/XP and have tried
various combinations of device types including
FILE_DEVICE_NETWORK_FILE_SYSTEM, FILE_DEVICE_NETWORK_REDIRECTOR, and
FILE_DEVICE_DISK_FILE_SYSTEM for the driver and the volume device. However
some combination such as using FILE_DEVICE_NETWORK_REDIRECTOR for both the
driver and the volume cause certain application such as copy and type to
not work as expected.

Does anyone know what are the correct device types to use in this
sittuation. I do not have the IFS kit so do not have any examples to go
on?

if you used DeviceTree, you will see that the LanmanRedirector uses
FILE_DEVICE_NETWORK_FILE_SYSTEM. since you have tried this before, could it
be some bug somewhere else?

Graham,

Your redirector device type should be FILE_DEVICE_NETWORK_FILE_SYSTEM.

But to make all apps happy it’s important to return a correct values from your
volume query information
routine when FsInformationClass = FileFsDeviceInformation.

I used following FILE_FS_DEVICE_INFORMATION structure’s values in my rdr:
->DeviceType = FILE_DEVICE_DISK; // LanmanRedirector does so
->Characteristics = FILE_REMOTE_DEVICE;

When I tried to use other values for DeviceType, some apps failed to work with
my redirected volumes.

Best regards,
Valeriy Glushkov
