3 <listitem><para>Tell <citerefentry><refentrytitle>smbd</refentrytitle>
4 <manvolnum>8</manvolnum></citerefentry> to enable WAN-wide browse list
5 collation. Setting this option causes <command moreinfo="none">nmbd</command> to
6 claim a special domain specific NetBIOS name that identifies
7 it as a domain master browser for its given <link linkend="WORKGROUP">
8 <parameter moreinfo="none">workgroup</parameter></link>. Local master browsers
9 in the same <parameter moreinfo="none">workgroup</parameter> on broadcast-isolated
10 subnets will give this <command moreinfo="none">nmbd</command> their local browse lists,
11 and then ask <citerefentry><refentrytitle>smbd</refentrytitle>
12 <manvolnum>8</manvolnum></citerefentry> for a complete copy of the browse
13 list for the whole wide area network. Browser clients will then contact
14 their local master browser, and will receive the domain-wide browse list,
15 instead of just the list for their broadcast-isolated subnet.</para>
17 <para>Note that Windows NT Primary Domain Controllers expect to be
18 able to claim this <parameter moreinfo="none">workgroup</parameter> specific special
19 NetBIOS name that identifies them as domain master browsers for
20 that <parameter moreinfo="none">workgroup</parameter> by default (i.e. there is no
21 way to prevent a Windows NT PDC from attempting to do this). This
22 means that if this parameter is set and <command moreinfo="none">nmbd</command> claims
23 the special name for a <parameter moreinfo="none">workgroup</parameter> before a Windows
24 NT PDC is able to do so then cross subnet browsing will behave
25 strangely and may fail.</para>
27 <para>If <link linkend="DOMAINLOGONS"><command moreinfo="none">domain logons = yes</command>
28 </link>, then the default behavior is to enable the <parameter moreinfo="none">domain
29 master</parameter> parameter. If <parameter moreinfo="none">domain logons</parameter> is
30 not enabled (the default setting), then neither will <parameter moreinfo="none">domain
31 master</parameter> be enabled by default.</para>
