Make your Telnet2 service look like this:

  SERVER-CONFIG> SHOW/FUL TELNET2
  Service "TELNET2":                                                   
          TCP socket (AF_INET,SOCK_STREAM), Port 2389
          Socket Options = SO_KEEPALIVE                                      
          INIT() = TCP_Init                                                 
          LISTEN() = TCP_Listen                                              
          CONNECTED() = TCP_Connected                                        
          SERVICE() = Internal_Telnet                                        
          Program = "MULTINET:LOADABLE_KERBEROS_TELNET"                      

The SERVER-CONFIG commands "COPY TELNET TELNET2", "SELECT TELNET2" and 
"SET INIT TCP_INIT" and "SET PORT 2389" should make it look like the above
display.  Then restart the master server with the SERVER-CONFIG command
"RESTART".
