HP CIFS Windows 2000 Interoperability (October 2002)

CIFS/9000 and Windows 2000 Interoperability

DNS is based upon a hierarchical namespace (represented by the dots in the names) that is

much more powerful and flexible than NetBIOS, and is designed to be distributed.

Additionally, DNS is implemented with the TCP transport protocol as opposed to UDP, so it

is a more network-efficient naming mechanism.

BIND is traditionally considered the “gold standard” of domain name resolution. Of course,

BIND is a complex and monstrous topic, which is why the definitive book on it is almost 600

pages long. Here, BIND is examined only by comparison to Windows 2000 DDNS.

6.2.1 BIND DNS on HP-UX

HP-UX 11 delivered BIND version 4.9.7. Most customers should immediately upgrade their

HP-UX 11 to at least BIND 8.1.2, which is available at no charge from

http://www.software.hp.com. This version of BIND includes the following features:

• DNS Notify (RFC 1996)

• DDNS Support (RFC 2136)

• SRV Record Support (RFC 2052 or 2782)

BIND v9 is also available from software.hp.com. It has the following added features:

• Incremental Zone Transfer (RFC 1995)

• DNSSEC (DNS security – authentication RFC 2535)

BIND v9.2 should be available from software.hp.com in September 2001.

6.3 Windows 2000 DDNS

Microsoft often refers to Windows 2000 DNS as “DDNS”, which represents “Dynamic” DNS.

“Dynamic” refers to the automatic DNS registration of nodes. This automatic registration is

accomplished with the DHCP client, which runs on every machine in the domain (servers

and clients), and registers both DHCP and statically configured clients. However, DDNS has

many interesting features and enhancements, and while the dynamic aspect of Windows

2000 DNS is a convenient feature, it is not necessarily the best feature of DDNS.

DDNS replaces both NetBIOS and WINS in the Windows 2000 domain. The default name

resolution is DNS, but Microsoft recommends leaving NetBIOS and WINS enabled for

compatibility. NT4.0 functionality is so pervasive – even within applications – that

assuming the enterprise is Windows-2000-specific is dangerous, even in Native Mode.

However, NetBIOS and WINS can be disabled (default is enabled):
