Hi Anand,
From Windows SAS 9.3 to which server are you trying to connect?
Ex1: If you are trying to connect to Linux/Unix Server.
%let server=192.168.1.1;
signon server.spawner user=<uname> pw=<password>;
rsubmit server.spawner;
%put "In to the server";
endrsubmit;
signoff server.spawner;
Ex2: To connect to Windows server i use the following code;
%let server=192.168.1.1;
options comamid=tcp remote=server;
signon server user="<username>" pw="<password>";
rsubmit server;
%put "hai server";
endrsubmit;
signoff server;
