Ensuring DNS resolves in TCP protocols

When you register a new IBM® Domino® server, you specify a common name for it. Within a Domino hierarchical name, the common name is the portion before the leftmost slash. For example, in the name App01/East/Renovations, the common name is App01. The common name, not the hierarchical name, is the name that the Domino server is known by in DNS.

Consider the DNS configuration, as well as the effect of other protocol name-resolver services, when you choose the format for the common name of the Domino server.

Note that these procedures listed the Related topics apply only to servers handling communications between IBM Notes® and Domino (NRPC services). If you administer servers that provide Internet services such as HTTP, SMTP, POP3, or LDAP, you can skip these topics, as these services use DNS directly.

Note: When you choose a common name for a Domino server that uses DNS, use only the characters 0 through 9, A through Z, and the dash (-). Do not use spaces or underscores.

Note: The DNS names held in Notes and Domino are not case sensitive; Notes workstations and Domino servers always pass DNS names to DNS in lowercase.
