It's just not that sophisticated. One machine is in charge of serving
clients that want to know the hosts in a workgroup (the domain master
browser). It looks like Administrators have chosen to restrict the
broswer service to only certain users. For example the account "GUEST"
is usuallydisabled by default these days. At a minimum you need valid
domain credentials but even then the administrators of the target domain
may restrict access further.

conceptually  similar and, more important, to tasks that have not
yet been conceived.
