I may be a newbie, but getting a shortcut like that was also one of my first priorities to preserve my sanity. This has helped me open remote without files on a IBM PC client and maybe it can help you too. I created a shortcut icon or typed the url in a browser which pointed to, for example,
fmp7://192.168.0.100/MENU.FP7
Assuming filemaker 7.0 was installed on each PC client, the PC server or host was located at 192.168.0.100 and the first table to open was MENU. If filemaker opened with no table, then the path or file could not be found or the server was not running. If filemaker never opened, then the fmp7 protocol was not registered on the client.
Why? I have never been able to add parameters to the Open File or Open Remote script. What *QuinTech* and *GuyC* suggested did not seem to exist in my version of FM7. Sigh.
