If you ask this way - there is none ... at least not via the 'servers' file.

Yes, during installation you will be asked for the server name. However, you 
may not name any. The result is a security hole because any NW server will be 
allowed to backup this client (and could steal data).

AFAIR, on UNIX/Linux, NW will add the '-s server' to the command that starts 
nsrexecd in the startup script. But this is only set on  this OS family.
