Document 1902 Troubleshooting Terminals 04/13/92 MG TROUBLESHOOTING TERMINAL HANGING PROBLEMS - MULTIUSER DOS 1. Make sure the user has the Multiuser DOS Business Update of September, 1991 or later. For upgrade information contact 1-800-NETWARE. 2. If hanging problems occur that do not occur under singleuser DOS, slow down all hardware options. The user could disable Turbo (if the computer has Turbo), disable shadowing, disable any onboard cache, and increase wait states in the CMOS setup. If the video card is anything other than standard CGA/EGA/VGA, switch the card or monitor to one of these standard modes. 3. To check for drive fragmentation, run CHKDSK *.* on the hard drive. The first time CHKDSK is run, the user should choose NOT to convert anything to files, and just see what's going to be converted. After the names of the affected files and directories have been noted, run CHKDSK *.* /F on the drive. NETDRIVE must be set to LOCAL in order for CHKDSK to run in Multiuser DOS. 4. Be sure to turn the computer off daily, to minimize the effect of memory fragmentation. (If 1k is used each time a program is loaded, eventually these 1k pieces will add up to all the available memory.) 5. Check the power supply. A dedicated, grounded line with surge protector is ideal. The humidity around the computer and peripherals ought to be kept between 40% and 60%, as static electricity can also cause hanging problems. 6. If the computer is too near appliances or the wall, or if the area isn't well ventilated, the computer could overheat and cause unpredictable problems. 7. Periodically (once every 6 months or so), the system administrator should open up the machine, clean the insides of the computer with canned air, and remove and reseat the cards, reseat the chips, and check the contacts. This will correct the effects of heat or dust on the computer.
