If you have the username and password, just call LogonUser() and
ImpersonateLoggedOnUser(). Then access your files. This will access the
files as the user that you logged on. Then you can call RevertToSelf() to
set the thread context back to the local system when you are done. Make sure
that you clean up these handles.
