AutoCAD is unable to locate the display driver because it has been moved or erased. AutoCAD Release 12 makes a DOS file open call that some networks do not support. This problem has been eliminated in the R12 386c2 update. Unable to open temporary configuration file. Consult your Novell documentation for more details.
Some networks have their own file handles setting.
See your network configuration manual for more information. AutoCAD R12 will not plot to a captured network parallel port. The ability to plot to a logical network port as well as to a physical port was added in the c2 update of AutoCAD-386. Houston Instrument plotters work with Release 10, but not Release 12. The Release 12 driver uses different communication settings from earlier versions.
