TeemTalk Connection Configuration
The Backup Tab
The options on this tab enable you to specify up to two additional servers as a backup in case the thin client cannot establish a connection to the standard server. If the thin client fails to connect to the standard server, it will try to connect to the server specified in the Backup Address 1 field. If that also fails, it will then try the server
Backup Address 2.
