Network dialup connections -- Troubleshooting
This topic describes how to troubleshoot a network dialup connection problem. You can also search for solutions to common problems on the Lotus Support Services Web site at www.lotus.com/support.

If a user installed, set up, and created Connection documents for a network dialup connection, but the user can't connect to it, check for these conditions and correct them, if necessary.

1. Make sure the workstation and/or server has been set up with the remote access client software. If the software hasn't been set up, users will get the message "Error initializing remote LAN service." Install the network dialup client software on the server and/or workstation, and then try connecting.

2. Make sure the remote server is accessible. If the modem is busy or the server is unavailable, the server can't answer calls.

3. Make sure that the user has the necessary privilege to use a network dialup connection to dial into the server. If necessary, modify the user's privileges. Also, make sure that the user is using the correct user ID password.

4. Trace the connection to the server. Check the resulting information for indications that the Connection document isn't properly configured. For example, common mistakes in the Connection document include not listing the current location or failing to enable the specified port(s).


5. Use the dialing method provided by the network dialup client to make the network dialup connection. If the connection fails, check for the correct configuration and check the modem for problems.

6. If the connection is successful, while the connection is still active, switch to the IBM® Lotus® Notes® workstation or IBM® Lotus® Domino™ server and attempt to connect to the destination server. At this point, the workstation or server should be connected to the LAN. You can temporarily set the Usage priority field of the network dialup Connection document to Low to force the connection over the LAN before using the Connection document.

7. If the previous step succeeds, drop the connection, switch to the Notes workstation, and choose File - Mobile - Call Server to call the remote access server. If you previously set the Usage priority field of the network dialup Connection document to Low, reset the priority to Normal.

8. Make sure you're using the correct Connection document. Then, make sure the information in the Connection document is correct.

After a successful modem connection, cannot establish session with server

The server is down.

The port is not configured on the Domino server.

The modem file on the server does not contain the correct connect string.

RAS is currently using the port that the Notes Direct Dialup connection is attempting to call on the destination server.

Modem does not respond

The modem is not turned on or is not connected.

The modem software is not configured properly.

COM device is in use

You try to access a server using Notes Direct Dialup and your server has RAS running and only one COM port.

You cannot create a RAS connection

RAS is not configured and/or started on the destination server.

Dial Up Networking is not configured properly on the client.

The modem software is not configured properly.

Error messages

This section lists common error messages displayed on the server console or at the Notes client, and provides information on what caused the error and how to recover from it.

Modem command files contains illegal character

You selected the wrong modem.

Select the correct modem file from the COM options - Modem type drop down box.

The selected modem command file only allows speeds as high as XXX

The configured modem speed exceeds the supported speed.

Check the maximum modem speed for your modem and configure it in the COM options - Maximum Port Speed.

Excessive Port or CRC errors on the last connection. Try enabling hardware flow control on the port or reducing the maximum speed settings

The configured modem speed exceeds the supported speed.

Enable flow control on the Notes client and Domino Server.

Reduce modem speed on the machine with Port and/or CRC errors.

Communications port unit number is not within valid range.

You have too many ports configured.

Set the valid number of ports on your system. Notes and Domino accept up to 64 ports.

No dialtone

The modem is not receiving a dial tone.

Check the phone line. Make sure that line is active and plugged into the modem properly.

If you are in Europe, make sure that you have disabled "wait for dial tone before dialing" in the COM options box.
