Apple Remote Access MultiPort Server - Manual (Page 97)

Connection attempt failed: incorrect password.
After a number of attempts, the user making the call did not enter a
correct password.
Listen error occurred on this port.
The modem could not be made to listen for an incoming phone call. First check
to see if the modem is on. If it is on, try switching the modem off and then on
again. Then turn the port off and then on again in the Port Configuration
window. Check the modem cable; it may be loose. If none of these measures
solves the problem, the modem script may be defective. Contact the modem
manufacturer for the latest Apple Remote Access modem script.
No available callback client was found.
The server received a connection request from a client but all the ports on the
server that can be used for calling back the client are in use. Check to make
sure all the ports are on.
General troubleshooting
A correctly registered user can’t connect to the server.
m Be sure that the port the user is dialing in to is configured correctly and is
turned on. Check the Port Configuration window to determine the status of
the port.
m Be sure the modem connected to the port is on, and that the cabling between
the port and the modem is correct.
m Another application, such as a terminal emulation program, may be using
the port the user is trying to dial in to. Check to make sure that no other
program is configured to use the port.
