Lotus Domino Administrator 7 Help - Lotus documentation

addition, you can use any IETF-compliant PPP communications server to dial into the network on which
the Domino server resides or though which the server can be accessed.
For more information on dialup connections, see the chapter ″Setting Up Server-to-Server Connections.″
On LANs, Lotus Domino is compatible with the TCP/IP and NetBIOS over the lower transport IP For
NetBIOS connections to work, both Notes workstations and Domino servers must use the same lower
transport.
For detailed information on which protocols are compatible with Lotus Domino for each supported
operating system, see the Release Notes.
Notes network ports
During the Server Setup program, Domino provides a list of Notes network ports based on the current
operating system configuration. If these ports are not the ones you want to enable for use with the
Domino server, you can edit the list during setup.
Because each network protocol consumes memory and processing resources, you might want to exclude
one or more ports and later remove the associated protocol software from the system.
In TCP/IP and NetBIOS, you can install multiple network interface cards (NICs) and enable additional
Notes network ports for each protocol, using the NOTES.INI file to bind each port to a separate IP
address or NetBIOS LANA number.
For more information, see the topic ″Adding a network port on a server″ later in this chapter.
Notes named networks
Consider Notes named networks in your planning. A Notes named network (NNN) is a group of servers
that can connect to each other directly through a common LAN protocol and network pathway -- for
example, servers running on TCP/IP in one location. Servers on the same NNN route mail to each
another automatically, whereas you need a Connection document to route mail between servers on
different NNNs.
When you set up Server documents, be sure to assign each server to the correct NNN. Lotus Domino
expects a continuous connection between servers that are in the same NNN, and serious delays in routing
can occur if a server must dial up a remote LAN because the remote server is inadvertently placed within
the NNN. Also bear in mind that the Notes Network field for each port can contain only one NNN
name, and no two NNN names can be the same.
NNNs affect Notes users when they use the Open Database dialog box. When a user selects Other to
display a list of servers, the servers displayed are those on the NNN of the user’s home server for the
port on which the Notes workstation communicates with the home server. Also, when users click on a
database link or document link, if a server in their home server’s NNN has a replica of that database,
they can connect to the replica.
Note: If a server is assigned to two NNNs in the same protocol, as in the case where the server has two
Notes network ports for TCP/IP, a Notes workstation or Domino server connecting to that server uses
the NNN for the port listed first in the Server document.
Resolving server names to network addresses in NRPC
Communications between Lotus Notes and Lotus Domino run over the NRPC protocol on top of each
supported LAN protocol. When a Notes workstation or Domino server attempts to connect to a Domino
server over a LAN, it uses a combination of the built-in Notes Name Service and the network protocol’s
name-resolver service to convert the name of the Domino server to a physical address on the network.
