Windows Server 2003’s DNS component is compliant with RFC 1995 and can doincremental transfers (known as IXFRs in DNS parlance) with other Windows 2000 or Windows Server 2003 servers supporting the feature. It also still can do the old-style full zone transfers, referred to as AXFRs, with noncompliant nameservers andwith non-Windows 2000 or non-Windows Server 2003 machines. There is not a wayto instruct Windows Server 2003 to always send full zone files to all servers, regard-less of whether they are compliant. You can, however, tell Windows to send incre-mental zone transfers to all supporting servers, regardless of whether they runWindows 2000 or Windows Server 2003. Here’s how: 1. Open the DNS Management snap-in. 2. Right-click your server and select Properties from the context menu. 3. Navigate to the Advanced tab, and uncheck the box labeled BIND Secondaries. 4. Click OK to finish. Now the server will use incremental zone transfers to all supporting servers, not justto those running Windows 2000 or Windows Server 2003.
