First to summarize I'm having two problems: 1) Non-Dedict File Server has problem running application programs that run fine on workstations. Giving File Server this Error message: ====> Invalid Command.com ... Cannot load Command, system halted. 2) Workstations have problem when one specific program is run from any machine. Workstations locks-up (even if not running a program) when workstations are re-booted, File Server is not found, but File Server is UP and running programs. We found a way around problem #1. Eventhough the system disk that boots the Non-dedict Server places a command.com in memory and the file server places another copy of command.com into memory, it is not enough. I still have to log-in and place a 3rd command.com into memory which allows operations to run smoothly. I have a menu program utility that was supplied my Novell running my application programs. When the 3rd command.com is not placed into memory, the menu program shows that the system does try to keep itself alive. Errors as follows: Invalid Command.com Can not start command, exiting Unable to create menu parse program (_oserr = 8) status of command was: -2 further program execution not possible exiting to system Invalid Command.com can not load Command, system halted. Workstations are not effected by this. Operations continue as normal. Problem # 2: We have a BASIC software package causing weird crashes on the Network. I wish we could get rid of the package but it the favorite from the 20 other packages that have been reviewed and it was used 3 yrs prior to the network. If any one cares it's a General Ledger program. The structure of the program is five chained sub-programs. Since all workstation lock-up at the same time when any machine(including F.S.) is running the program, there is no way of working with the workstations after a crash. Since the Server doesn't get effect by this odd crash, monitoring the workstations doesn't prove helpful. First problem there is NO ERROR Message, other than the file server has disappeared for these workstations but continues to operate while the workstations crash. Second problem is the program doesn't always crash in the same of the sub-program, but seems to crash just prior to chaining or during the chaining. Because of the delay on the Ethernet exactness is hard achieve. The sub-program does close files before crashing so data for that workstation is safe. I'm hoping the two problems are connected somehow because it has been puzzling me the whole month of August and I feel I've reached a dead end. I don't post articles often and don't have a signature, but all needed info should be found in this article Header.

Please note that header now reads ......... cook@sybil.UUCP P.S. In problem #1 error message only occurs when exiting the application program. Send Help soon. John M. Cook
