Garry,                                                                
                                                                      
Erlang node names use either fully qualified domain names or          
"shortnames" for the host part of node name.                          
This is controlled by the "-name" (FQDN) and "-sname" (short name)    
switches.                                                             
                                                                      
To resolve your problem:                                              
a1) replace "-name node" with "-sname node" to use shortnames         
or                                                                    
a2) try to contact "kestrel.sage.att.com" instead of "kestrel".
