[Windows] I can't create named node

[Lee Samuel]

Neither -name nor -sname can make one successfully.
 
If I open Eshell, and enter command:
 
    net_kernel:start(['sam_1@REDACTED', shortnames]).
 
then I get the following response:
 
    =INFO REPORT==== 15-Feb-2011::12:00:05 ===
    Protocol: "inet_tcp": register error: {{badmatch,{error,ewouldblock}},
                                           [{inet_tcp_dist,get_tcp_address,1},
                                            {inet_tcp_dist,listen,1},
                                            {net_kernel,start_protos,4},
                                            {net_kernel,start_protos,3},
                                            {net_kernel,init_node,2},
                                            {net_kernel,init,1},
                                            {gen_server,init_it,6},
                                            {proc_lib,init_p_do_apply,3}]}
    {error,{shutdown,{child,undefined,net_sup_dynamic,
                            {erl_distribution,start_link,[[sam_1@REDACTED,shortnames]]},
                            permanent,1000,supervisor,
                            [erl_distribution]}}}

I have no idea about this, please help me.    :-)
