Is it possible to create a symbolic link to for an user, or all users, from
a UMDF driver to \DosDevice\k: or simulair?
Was thinking using Impersonate, but the driver fails and restart as soon
as I use the device object in the impersonate callback.
Creating files or simulair works as impersonated user,
but not creating a symbolic link.
Perhaps there is an easier way also. Like using DefineDosDevice to a
special interface in the user mode app?

You cannot make any object calls in the impersonation callback.
What happens when you call IWDFDevice::CreateSymbolicLink outside of impersonation?

Well, first let’s say that I’m running on Windows Vista, with DDK 6000.
The call to CreateSymbolicLink goes successfull but I assume that the
link is created for the localservice account, because my normal user
never recieves any new device letter. Therefore my Impersonate idea.
But hopefully there is a better way?

Tried \DosDevice\k: and also \DosDevice\Global\k:
and of course is these not used before.
Also tried with DefineDosDevice, but was not really sure what to
use for path here. It feels like it worked a bit different in the WDM
time…

Just a guess, but you probably have to communicate with the mountmanager to dynamically bring drive letters online.

You might want to look at IOCTL_MOUNTMGR_NEXT_DRIVE_LETTER is the WDK, and mountmgr.h.
Good luck,
mm
You’ll need to make the link in \DosDevices\Global or it won’t be visible outside the services session.
And how do you determine that they are not working? Are you looking for them in the explorer? Did you write a program to open \.\k<file:>: and that’s failing?

…or rather IOCTL_MOUNTMGR_CREATE_POINT.

That would work even better!

You know what would be even better? Not replying to a12 year old post!
