gdomap -H gives you the options but ...

Probably trying to use gdomap inappropriately when you don't want/need it.

The gdomap deamon is completely unused for most applications!   I don't think 
any GNUstep applications use it in normal operation (ie if you haven't given 
them command-line options to tell them to communicate between different 
hosts/users).  The vast majority of DO connections are private to a single user 
on a single machine and use message ports (implemented as unix domain sockets 
or as message queues on mswindows) and they don't need/use a namesperver as 
name information is written to the local filesystem (or windows registry).

The usual cause for name registration to fail is if another process exists 
using that name ... removing the directory containing the files representing 
the names will of course cure that

If you want to get into the details, look as NSMessagePortNameServer.m ... If 
you want to write a tool to list/manage ports (which might be a nice addition 
to the base Tools area), the information you need should be contained in that 
file.
