The Lotus Domino server is installed on a Windows 2008 R2 (or above) server, and when the administrator tries to start the Lotus Domino Console i.e. the Java Controller for Domino, it gives the below error message.

Either the Server Controller is not running on the host Server/Name or is not listening on port 2050

Resolving this issue

There are multiple methods to resolving this issue:

• Add the entry for the IP address which is mapped to server name in the local host file (e.g 10.10.10.5 Server/Name).

• Enable the below notes.ini parameter in the Domino server's notes.ini.

ServerController=1
TCPIP_ControllerTcpIpAddress=<ip address>:2050

Where: <ip address> is the IP address of the Domino server.

• With the above settings done, restart the Operating System (OS).
