When you install the iSeries Access on your PC, there is a service that is installed titled iSeries Access for windows Remote Command. (Control Panel->Administrative Tools->Serivces) Check and see if this service is running. If it is not, it needs to be running in order to do the remote procedure call using the RUNRMTCMD. If you do not see the service in your list of services, Look up the program CWBRXD.EXE. This should give you the details on how to install and run this service.
