"but it does not show up as a device in Explorer until I reboot."
Are you means that after reboot, the "Z:" will show in Explorer ???
In my implement, after I install my driver, I can run a little program to
send an IOCTL, which let the driver dynamic create a FDO.
In one of my test, after the FDO created correct (does not create symbolic
link), I call DefineDosDevice() in user-mode application, the "Z:" will show
in explorer at once. But I must be administrator to call DefineDosDevice(),
else the system may say "Access Denied", that's a big problem.
Any one know this issue?? Help please.
