If the person cannot access the login page at all, it is usually actually a connectivity issue (see “Ping & traceroute” and “Configuring the network settings”) unless all accounts are configured to accept logins only from specific IP addresses (see “Trusted Host #1”).

If an administrator can connect, but cannot log in, even though providing the correct account name and password, and is receiving this error message:

single administrator mode may have been enabled. See “Enable Single Admin User login”.

If the person has lost or forgotten his or her password, the admin account can reset other accounts’ passwords (see “Changing an administrator’s password”).
