Updating the Device Driver for a DOS Network Server
If you are using the DVD-ROM drive in a DOS Network server, you need to make the following changes:
If you are using DOS 3.3, be sure that you have PC Local Area Network
(LAN) Program Corrective Service Diskette level IP00755 or later installed.
If you are using DOS 4.0, be sure that you have DOS Corrective Service
Diskette level UR 29015 or later installed. (The computer cannot be configured
as an Extended Services Domain Controller for the IBM PC LAN Program.)
