Resolve “Unable to find path to server” Error in Lotus Notes

Know methods to overcome the errors in Lotus Notes like “unable to find any path to server”, “Remote System No Longer Responding”, etc.

Basic Error in Lotus Notes

Sometimes when a Lotus Notes user tries to connect to the Domino Server, then he may get some error messages like:

“Unable to find path to server”
“Remote System No Longer Responding”
“The Server is not responding”

All these error messages may arise if there is any connection issue between Lotus Notes and Domino server. You can check the connections by tracing TCP/IP by clicking on File >> Preferences >> User Preferences >> Ports >> Trace (Lotus Notes email client) or Trace Command (Domino Server). A message can be displayed: “The remote server is not a known TCP/IP host.”. It is possible when the connection is not recovered by rebooting the operating system or Notes client configuration.

Various Causes and Their Solutions

  1. When CLASSPATH or CLASSPATH.SAVED is not set

    Sol: It is used only in Lotus Notes email client. You can resolve it by the following steps:

    • Right-click on My Computers and then select Properties.
    • Go to Advanced tab and then click on Environment Variables.
    • To add a new system variable, click on “New”. Now set to anything for CLASSPATH= or CLASSPATH.SAVED=.
    • Click on Save to save the added variable and finish the process.

  2. When old and obsolete IP addresses are cached by Notes

    Sol: You need to create a new location document to overcome this problem. Follow below steps:

    • Create a new location document in Names.nsf locally. It will help in forcing Lotus Notes to restrict the use of cached “last known good address” which is kept in the reboot.
    • Now you need to create a formula agent in the location document by following steps:
      • Open Notes email application. Click on Create >> Agent.
      • In Agent Properties, click on Basics >> enter the name of the agent in the Name field.
      • You can select Shared if you want the agent to be used by other users or Private if only you want to use that agent.
      • You can specify some settings if the agent will search for text in documents. A user can check “Store search in Search bar menu” to show the query in the Search bar. A user can also check “Store highlights in document” to highlight the search matches in the searched documents.
      • Now choose one of the triggers in the runtime section. Like “On event” to select the event or “On Schedule” to schedule the time. You will select the documents which depend on the trigger you have selected.
      • Click on the Security tab and set up its properties. Then close the box.
      • Click on Add Action and specify any simple action for the agent.
      • Select Objects tab >> Document Selection >> Add Condition to allow agent to search for a document.
      • To save the agent in the application, click on File >> Save.
    • Now, you need to create a formula agent to clear all the fields in the Location document by the following code:

    • FIELD $SavedAddresses:= "";
      FIELD $SavedPorts:= "";
      FIELD $SavedServers:= "";
      FIELD $SavedDate:= "";
      FIELD $SavedTriedDate:= "";

  3. The remote server is not a known TCP/IP host

    Sol: You need to check whether the connection between the Notes client and Domino server exists or no. To see the selected location, check the status bar. “Offline” means that Notes client is not connected to the Domino Server.

    Offline mode

    If you have multiple Domino servers in your environment, then try to access a different server. Click on File >> Open >> IBM Notes Application >> Enter a different server. But if again the issue occurs then contact to help desk.
