Does anyone know if IoCreateFileSpecifyDeviceObjectHint() works for
redirectors?
I’ve tried to use it on LanmanRedirector, but get STATUS_INVALID_PARAMETER
returned if the DeviceObject field is anything other than NULL. I’ve also
tried setting IO_NO_PARAMETER_CHECKING, but this seems to make no
difference.
Also if the DeviceObject field is set to NULL the
IO_IGNORE_SHARE_ACCESS_CHECK seems to be ignored.
Thanks

There was a bug in this for Windows XP that would cause
IoCreateFileSpecifyDeviceObjectHint() to return STATUS_INVALID_PARAMETER
if the DeviceObject was anything other than NULL. The Microsoft
Knowledge Base Article 322726 describes this bug. This was fixed in
Windows XP SP1.
