Sometimes a solution consists of several files. Developers often use the Don't Display in Open Remote dialog option to hide all files but one from the user to eliminate confusion as to which file they should select to open the system.
If you want to eliminate the Open Remote dialog completely, install an opener file on each desk top. The opener file includes a one line script: Open File which you set to open the hosted file for the user. Then, in file options, select this script to run automatically when the file opens.
