HELP: ERROR -468

I need some help, I am developing an application which uses a Sun Sparc running Solaris 2.3 and I-NET version 5.02 trying to connect to an HP 9000/877 server running Informix ONLINE and I-STAR version 5.03. When my application attempts to connect to the database server I get an error -468 which says "....cannot get user id from the system passwd file..... I can rsh to and from the server without any problem (and without a password). There is no NIS (Yellow pages running) or remote mounted file systems involved. I know that there has to be an entry in the /etc/services file on the HP that the sqlexecd looks for. My question is: does the HP have to be rebooted for the daemon to see the port or will starting the daemon pick it up?? or I am I missing something else?? NOTE: It is difficult for me to reboot the server as there are other applications up and running. Anybody have any suggestion! Thanks in advance --Stevec
