Or just link them statically.

Not sure whether this can be fixed at all. The nfsd server requires
that nfs clients connect from a TCP port < 1024, and Windows just
doesn't allow a bind() to a port < 1024. I had that debate with
Roland, and for now its "under investigation" what could be done.

BUG: Windows 11 Explorer shows  the NFS mount as "disconnected"

Agreed.

Many thanks go to Roland Mainz and Tigran Mkrtchyan for working on this
