How can I open the file in the network machines in kernel modes.
Can ZwCreateFile achieve this?

You need to use the MUP device to resolve the network addressing e.g. a
file path will be something like:

\device\MUP\ServerName\ShareName\DirName\FileName

Security is an interesting problem when accessing files across a network in
kernel mode. The security on the network share is in the context of the
user who opened the share. You driver must execute it’s requests with the
security context of the relevant user.
