Background: 17 node network license AutoCAD 2002 NT network w/ Windows 2000 & XP clients HP1055CM Plus plotter Plot specific files stored on a network shared drive: x:\drafting\autocad\plotters (*.pc3) x:\drafting\autocad\drv (*.pmp) x:\drafting\autocad\plot styles (*.stb) AutoCAD | Options - search paths are set to look at network locations The Problem: We have AutoCAD installed on 22 workstations. One of the workstations refuses to accept the network installed plot settings. The file search path is correctly set in the preference file and is the same as every other workstation. For the workstation not working correctly, as soon as you try to plot it give a null pointer error and will not accept the network plotter files. This null pointer error also corrupts the file and requires a recovery before opening the file on a different workstation. This has happened on one other occasion on a different workstation. The last time this problem occurred, we were forced to uninstall AutoCAD, scrub the registry of AutoCAD settings, and reinstall. I would like to think there is a logical explanation to this problem and a simpler fix than a total reinstall. Does anyone have any suggestions or help to offer?
