-	registry key in Windows 2000 and Windows NT.  When set to 0, user
-	and group list information is returned to anyone who asks.  When set
-    to 1, only an authenticated user can retrieve user and
-    group list information.  For the value 2, supported by
-    Windows 2000/XP and Samba, no anonymous connections are allowed at
-    all.  This can break third party and Microsoft
-    applications which expect to be allowed to perform
-	operations anonymously.</para>
+	<para>
+		The setting of this parameter determines whether SAMR and LSA
+		DCERPC services can be accessed anonymously. This corresponds
+		to the following Windows Server registry options:
+	</para>
+
+	<programlisting>
+		HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\RestrictAnonymous
+	</programlisting>
+
+	<para>
+		The option also affects the browse option which is required by
+		legacy clients which rely on Netbios browsing. While modern
+		Windows version should be fine with restricting the access
+		there could still be applications relying on anonymous access.
+	</para>
 
 	<para>
-    The security advantage of using restrict anonymous = 1 is dubious,
-    as user and group list information can be obtained using other
-	means.
+		Setting <smbconfoption name="restrict anonymous">1</smbconfoption>
+		will disable anonymous SAMR access.
 	</para>
 
-	<note>
 	<para>
-    The security advantage of using restrict anonymous = 2 is removed
-    by setting <smbconfoption name="guest ok">yes</smbconfoption> on any share.
+		Setting <smbconfoption name="restrict anonymous">2</smbconfoption>
+		will, in addition to restricting SAMR access, disallow anonymous
+		connections to the IPC$ share in general.
+		Setting <smbconfoption name="guest ok">yes</smbconfoption> on any share
+		will remove the security advantage.
