HP Advanced Server V7.3B for OpenVMS

For information on supported network transport software, see the section SOFTWARE

REQUIREMENTS.

NetBIOS Interface

The Advanced Server supports the NetBIOS interface in TCP/IP, DECnet, and NetBEUI

networks, using multiple transport stacks on a single controller or on different network

controllers. However, a NetBIOS programming interface is not provided.

NetBIOS support under TCP/IP includes both a p-node and a b-node RFC 1001/1002

implementation. Therefore, the NetBIOS interface can be used under TCP/IP in both LAN and

WAN environments. The Advanced Server Conﬁguration Manager utility allows you to select

one or more of the following methods for NetBIOS name resolution for WANs:

• LMHOSTS ﬁle

• Windows Internet Name Service (WINS)

• DNS

Note: Enabling DNS allows the server and clients to use a speciﬁed DNS name server

for NetBIOS name resolution as a last resort if all other methods fail to resolve a NetBIOS

name. DNS is also used by server clients to resolve the server cluster alias and to

provide dynamic load balancing and failover on servers in an OpenVMS Cluster in a WAN

environment. The DNS name server used for load balancing must support dynamic updates

(Berkeley Internet Name Domain [BIND] server, Version 8.1.1 or later).

DNS is not conﬁgured as a replacement for WINS or LMHOSTS but rather as a supplement.

The Advanced Server still uses WINS, LMHOSTS, or broadcast methods for resolving

names.

Note Advanced Server for OpenVMS supports dynamic purging and reloading of the NetBIOS

name cache, and the ability to display the name cache contents — similar to the NBSTAT

capabilities provided on some Microsoft clients.

Flexible Security Models

The Advanced Server allows you to choose one of two modes of security, depending on the

needs of your environment:

• In Advanced Server Only mode, only the Advanced Server (Windows NT Server style)

security model is enforced.

This mode is sufﬁcient for most network environments. The Advanced Server employs a

user-level security model that provides precise control over access to shared resources,

including disk devices, directories, and printers. Control is based on a password assigned

to each user account and the speciﬁc access permissions deﬁned for the resources.

The Advanced Server incorporates enhanced features that provide a high level of control

over user and resource permissions and auditing. These features include support of

discretionary access control permissions on individual ﬁles, directories, and resources and

complete auditing capabilities.
