Hi,<br>Sorry, did you e-mail me and get my Word Doc of Clipper and Networks along with Printer.lib file ? <br><br>Under NT4 ( all Service Packs ) I changed/added the opportunisitc locks setting in the registry on both the server and workstations. This also allpies to W2000 workstations.<br><br>Don't know the Windows adv server version. I have had my clipper apps running smoothly on many NT setups. The main problem I had to contend with was 100% processor usage and printing. To restrict users I created a table of printers with the network names that the app could print to. Then piped Net Use to a file and read the contents. If the user was connected correctly then printing proceeded, if not, displayed settings and asked used to connect to a valid printer.
