+	/// <remarks>
+	/// This class represents a NetBIOS over TCP/IP address. Under normal
+	/// conditions, users of jCIFS need not be concerned with this class as
+	/// name resolution and session services are handled internally by the smb package.
+	/// <p> Applications can use the methods <code>getLocalHost</code>,
+	/// <code>getByName</code>, and
+	/// <code>getAllByAddress</code> to create a new NbtAddress instance. This
+	/// class is symmetric with
+	/// <see cref="System.Net.IPAddress">System.Net.IPAddress</see>
+	/// .
+	/// <p><b>About NetBIOS:</b> The NetBIOS name
+	/// service is a dynamic distributed service that allows hosts to resolve
+	/// names by broadcasting a query, directing queries to a server such as
+	/// Samba or WINS. NetBIOS is currently the primary networking layer for
+	/// providing name service, datagram service, and session service to the
+	/// Microsoft Windows platform. A NetBIOS name can be 15 characters long
+	/// and hosts usually registers several names on the network. From a
+	/// Windows command prompt you can see
+	/// what names a host registers with the nbtstat command.
+	/// <p><blockquote><pre>
+	/// C:\&gt;nbtstat -a 192.168.1.15

+	/// for a host one might do:
+	/// <pre>
+	/// InetAddress addr = NbtAddress.getByName( "jmorris2" ).getInetAddress();
+	/// </pre>
+	/// <p>From a UNIX platform with Samba installed you can perform similar

+	/// <summary>
+	/// An Access Control Entry (ACE) is an element in a security descriptor
+	/// such as those associated with files and directories.
+	/// </summary>
+	/// <remarks>
+	/// An Access Control Entry (ACE) is an element in a security descriptor
+	/// such as those associated with files and directories. The Windows OS
+	/// determines which users have the necessary permissions to access objects
+	/// based on these entries.
+	/// <p>
+	/// To fully understand the information exposed by this class a description
+	/// of the access check algorithm used by Windows is required. The following
+	/// is a basic description of the algorithm. For a more complete description
+	/// we recommend reading the section on Access Control in Keith Brown's
+	/// "The .NET Developer's Guide to Windows Security" (which is also
+	/// available online).
+	/// <p>
+	/// Direct ACEs are evaluated first in order. The SID of the user performing
+	/// the operation and the desired access bits are compared to the SID
+	/// and access mask of each ACE. If the SID matches, the allow/deny flags
+	/// and access mask are considered. If the ACE is a "deny"
+	/// ACE and <i>any</i> of the desired access bits match bits in the access
+	/// mask of the ACE, the whole access check fails. If the ACE is an "allow"
+	/// ACE and <i>all</i> of the bits in the desired access bits match bits in
+	/// the access mask of the ACE, the access check is successful. Otherwise,
+	/// more ACEs are evaluated until all desired access bits (combined)
+	/// are "allowed". If all of the desired access bits are not "allowed"
+	/// the then same process is repeated for inherited ACEs.
+	/// <p>
+	/// For example, if user <tt>WNET\alice</tt> tries to open a file
+	/// with desired access bits <tt>0x00000003</tt> (<tt>FILE_READ_DATA |
+	/// FILE_WRITE_DATA</tt>) and the target file has the following security
+	/// descriptor ACEs:
+	/// <pre>
+	/// Allow WNET\alice     0x001200A9  Direct
+	/// Allow Administrators 0x001F01FF  Inherited
+	/// Allow SYSTEM         0x001F01FF  Inherited
+	/// </pre>
+	/// the access check would fail because the direct ACE has an access mask
+	/// of <tt>0x001200A9</tt> which doesn't have the
+	/// <tt>FILE_WRITE_DATA</tt> bit on (bit <tt>0x00000002</tt>). Actually, this isn't quite correct. If
+	/// <tt>WNET\alice</tt> is in the local <tt>Administrators</tt> group the access check
+	/// will succeed because the inherited ACE allows local <tt>Administrators</tt>
+	/// both <tt>FILE_READ_DATA</tt> and <tt>FILE_WRITE_DATA</tt> access.
