Integrating a Windows Server 2003 DNS Infrastructure Into an Existing DNS Namespace

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

Windows Server 2003 DNS is standards-compliant and interoperates with other implementations of DNS, including Microsoft® Windows NT® version 4.0, BIND 9.1.0, BIND 8.2, BIND 8.1.2, and BIND 4.9.7. The complexity of your integration process depends, in part, on the DNS features that you need to support. If the computers in your DNS infrastructure are running versions of DNS that support the same features, then integrating the Windows Server 2003 DNS infrastructure is a simple process. If the computers in your DNS infrastructure are running versions of DNS that do not support the same DNS features, then the integration process is more complex.

Table 3.5 compares feature support in Windows Server 2003 DNS and other implementations of DNS.
