Hello, I am constantly confronted with the problem that, when some dgns are in folders too "far" away from my active dgn, I can't reference them because MS SE only allows for 65 characters. By seting the variable MS_RFDIR, I can overcome the problem locally, but then these settings have to be on every machine that opens my dgns (a logistical problem with 150 workstations spread all around the country). A collegue told me he had once seen a ucm that specified that, when looking for a reference, one need only specify the harddrive letter, then MS would find the references. Unfortunatly he doesn't know how to make this ucm, and neither do I :-( But I'm sure someone here can help me to solve this problem? Thanks!
