Ouch. We strongly recommend to NOT use local protocol over network
drives. There are a number of problems that can happen, up to
corrupting your repository and losing entire history of files to
corruption. This is a very dangerous configuration.
You should instruct your client to set up a CVSNT server and use a
standard protocol (e.g. sspi, sserver, or ssh).

It's telling you to use the -N global switch to override that warning.
However, note my warnings above.

Unfortunately, Yes.

Some time ago the -N was added and the behavior to block by default was
added when uneducated users had some problems running across a network
link. They didn't know any better -- so the warning was added.

See above.

That is correct.
