This error usually means the share name is incorrect. Have you checked
your fstab file for extraneous characters, bad line-ending, that kind of
stuff? Try "cat -vet /etc/fstab" as that will show control characters.

You also have quite different options in the fstab line versus your
shown command line, but I suspect you tested many combinations already
and just pasted one of the iterations.

Also, try to start with a simpler fstab line. For example:
//192.168.1.200/Drive_E /mnt/server_e cifs 0 0

And go from there if it works.

Regarding the documentation, the cifs mount options are listed in the
mount.cifs manpage

Some people have also been getting hard to debug cifs errors and fixed
them by installing keyutils. I can't say that's the case here, as the
command line works and I don't see evidence of kerberos authentication,
but you might try that.
