  1. Sure you can. Just keep returning STATUS_REPARSE until it succeeds on the
    devie that you want.

Thanks all for your help! A few more questions:
(1) If I decided to add support for redirecting local disk requests
to another server or redirecting other server requests to the
local disk. Can I still use \Device\LanmanRedirector?? Doesn’t
the \Device\LanmanRedirector only handle network server??
(2) Is there a way I can use \Device\LanmanRedirector without
first mapping the server to a drive letter?? For example,
can I access the server share using something like:
\Device\LanmanRedirector\server\share
(3) I don’t think I can use STATUS_REPARSE. Reason being in some
cases after I redirected the request to one server, I want to
redirect the request again to another server if that first one
failed. If I use STATUS_REPARSE, I would never get the result
status of the first redirected request. Am I right??

Thanks,
Patrick
