NETWORK CONFIGURATION

Ensuring DNS resolves on Windows systems -- All TCP protocols
If an IBM® Lotus® Domino™ server is a Microsoft® Windows® system, often two name services exist on the system -- NetBIOS over IP and DNS. If you assign the same name to both the Domino server and the system, client applications that use either the Notes Name Service or DNS can encounter name-space ghosting between the two names. In other words, because the NetBIOS record for a system's host name has already been found, the name resolving process ends and the DNS record for the Domino server on that system is never found.

Note For a Domino server on Windows 2000, problems occur only if you enable name services for NetBIOS over IP in order to join an NT domain using Server Message Blocks (SMB).

To prevent this problem:

1. Add a preface such as W2K- to the system name, using the Network Identification tab on the System Properties dialog box.

2. Create an A record (or, for IPv6, AAAA record) in DNS for the system name. The IP address is the same as the one for the Domino server.

3. Create a CNAME record in DNS for the Domino server's name, linking it to the system name.

For example, for the Domino server BosMail02/Acme, the common name is BosMail02. You name the system NT-BosMail02. You create an A record in DNS for NT-BosMail02.acme.com and a CNAME record for BosMail02.acme.com, linking it with NT-BosMail02.acme.com.
