1. Check that the IBM® Lotus® Domino™ server and the network are running.

2. Check if the server has been renamed or recertified. When a user tries to open a database on a server that has been recertified or renamed, the message "Server not responding" may appear. Users should use the new server name to open the database.

3. Check the Server document for an invalid or nonexistent host name as the IBM® Lotus® Notes® RPC proxy. From the Domino Administrator, click the Configuration tab and open the appropriate Server document. Click the Ports - Proxies tab. A Domino server that is configured to use TCP/IP can't transfer mail or initiate replication with another server in the local domain if the host name is invalid or nonexistent. In addition to "Server not responding, " "No Path Found to Server" and "Proxy Reports that the Connection Request Failed" messages may appear.

A Domino server configured to use a Notes RPC proxy attempts to route all outbound connection requests through the listed proxy, whether or not the proxy exists. Because most Domino systems don't use an RPC proxy, this field should generally be left empty.

Note If full trace logging is enabled in the NOTES.INI file, the log file records detailed information about failed attempts to connect to a remote server. The PassThru_LogLevel is typically set 0 to minimize unnecessary logging.

Also, filters might prevent broadcast traffic from Notes from crossing a bridge or router. Bridges and routers are often configured to suppress broadcast traffic by default, and NetBIOS uses broadcasts to communicate on networks.
