Troubleshooting log on problems
Invalid credentials
The subscriber sees messages such as “Invalid credentials. Please retry” or “The server could not
be located. Please Retry.”
1 On the subscriber’s computer, check that Unified Messaging is configured with the proper
settings. Verify that the following information is correct:
• mailbox number
• fully qualified domain name (FQDN) or IP address of the Business Communications
Manager system
• the SMTP/VPIM prefix of the Business Communications Manager system
2 Check that you can log on from the telephone using the same mailbox number and password.
3 Verify that you have network connectivity to the Business Communications Manager system.
For example, issue a network command to the Business Communications Manager system
exactly as it appears in your Unified Messaging configuration. Try to ping using the DOS
prompt, and ensure that you receive a valid response from the Business Communications
Manager system. If you do not have network connectivity to the Business Communications
Manager system, you are not able to access Unified Messaging.
4 Ensure that DNS is configured on this computer. Under TCP/IP properties, select the DNS tab.
Ensure that a DNS server is listed. Verify that it is the correct IP address for the DNS server.
5 Check with the DNS administrator whether the server name is in the DNS server. Verify that
the correct hostname is configured in the DNS server.
6 The following actions can be taken to resolve this situation:
• The CallPilot FQDN must be properly configured in the DNS server.
• Refer to “Configuring environments without a DNS” on page 13 for instructions on
configuring CallPilot Unified Messaging in an environment with no DNS server.
