The Domino server is a collection of services called tasks.

| nrouter | Router | Mail router for sending NRPC mail. |
| nprocmon | Process Monitor | Monitors server tasks for failure, initiates Domino fault and restart when occurs. |
| namgr | Agent Manager | Runs scheduled agents - usually multiple instances. Number of namgr tasks depends on day vs night settings in server document. |
| nadminp | Administrative Process | Performs many of the tedious and multi-step maintenance tasks in a Domino Domain (environment). |
| nhttp | HTTP Server | Runs the Domino web server. Run on all servers hosting web mail or web applications. |
| nldap | LDAP Server | Runs the Domino LDAP server on administrative server for Lotus Domain. Not usually run on other Domino servers. |
| nsmtp | SMTP Server (Listener) | Used for Domino servers receiving SMTP mail from Internet. Otherwise, not needed. |
| nreplica | Replicator | Replicates / syncs changes within same applications between Domino servers. Needed if you have more than one Domino server. |
| nevent | Event Monitor | Monitors system for events to handle. |

| npop | POP3 | Provides mail POP3 server for Domino that handles mail clients that use the POP version 3 format. (Use IMAP instead if politics allow as it supports server-based folders, mail stays on server for easier backup.) |
Statistical Tasks
(Generally run on hub servers unless specified)

| nstats | Stats | Generates statistics for a remote server on demand. (Run on a "spoke" server for a "hub" server to request statistics.) |
| nstatistics | Statistics | Records "this" server database activity in the stats log file. By default, runs via notes.ini at 5:00 AM. |
| nrunjava | RunJava ISpy | A runjava option, allows admins to send mail probes to test mail routing w/o having to send test e-mails. |

| |
trace myserver/MyOrg
or
trace myserver | performs connection test for routing and replication and confirms if encryption or compression is enabled for the connection |
| |
| tell router update config | updates the router task's in-memory configuration to the actual configuration documents |
| tell router show | status state and current router threads displayed to Domino console |
| tell router list main | list the mail in mail.box and their state to the Domino console |
| tell router dump routing tables | Displays the current routing tables to the Domino console |
| |
| tell smtp update config | updates the SMTP (receiving SMTP mail) task's in-memory configuration to the actual configuration documents in the Domino directory |
Notes:
The filenames assume MS Windows installation. Drop the leading n for Linux.
A complete list is the the Administator Help database, do a search on "Domino server tasks".
Other common tasks that exist are tasks for Domino Clustering, Transaction Logging, and a slew for Lotus Sametime (Instant Messaging).
