2.1 3Com Networks Windows Setup recognizes the following 3Com networks: . The 3Com 3+Share network is based on the Microsoft Network product and will be handled as such by Windows. See the "Microsoft Network and Compatibles" section later in this document. . The 3Com 3+Open LAN Manager network is based on Microsoft LAN Manager and will be handled as such by Windows. See the "Microsoft LAN Manager Networks" section later in this document. When you install for 3Com 3+Share or 3Com 3+Open LAN Manager, Setup adds the following entries to the [386Enh] section of your SYSTEM.INI file: TimerCriticalSection=10000 UniqueDOSPSP=TRUE PSPIncrement=5 See SYSINI.WRI for more information on these entries. In addition: . Some copies of 3Com 3+Open LAN Manager version 1.1 require a maintenance upgrade to work with Windows. If you encounter problems, contact your network customer-support organization. . When you install Windows, Setup modifies your AUTOEXEC.BAT file to make sure the Windows directory appears in your path ahead of any conflicting directories. However, the 3+Share network might change this path when you log in. If so, your system administrator must modify the network log- in procedure so that the path is set correctly to run Windows. . On a 3Com 3+Open network, the user's name displayed by Windows Print Manager might not match the user's actual log-in name. . Some 3Com 3Station diskless workstations come with an All ChargeCard. Make sure your machine is not configured to load the network into the upper memory area between 640K and 1 megabyte, as this will not work reliably with Windows version 3.1 in standard mode. You will not be able to set up Windows if your system is configured in this way. . If you use the 3C505 Network Adapter Card, you must disable the Link Plus Optimizer to run Windows in 386 enhanced mode. You can disable it by removing the following lines from your CONFIG.SYS file: device=psh.sys device=pth.sys In addition, remove the following line from your AUTOEXEC.BAT (or any other batch file you use to start your network): ldr . Windows does not support the 3Com network aliasing scheme (three-part names). "2.2 Artisoft LANtastic LANtastic versions below 3.0 are not compatible with Microsoft Windows. For information about LANtastic versions 3.x or 4.x, see the specific sections that follow. The following notes apply to both versions. . The EMMExclude setting, added to the SYSTEM.INI file during Setup, is required for the default configuration of the Artisoft LANtastic Enhanced 2mbps network adapter. If you have changed the memory address setting on your adapter, modify this entry in SYSTEM.INI to reflect the appropriate address range. If you are not using this network adapter, you can remove this entry. . Some commands require the NetHeapSize entry in the SYSTEM.INI file to be set higher than the default value; for example, xcopy requires NetHeapSize=128. Increasing the NetHeapSize value leaves less memory available for non-Windows applications, so only increase this value if necessary. For more information about the NetHeapSize entry, see the SYSINI.WRI file. . You cannot create a permanent swapfile while running Windows on a LANtastic server. To create a permanent swapfile, restart your computer without loading the server software, and create the swapfile in Windows. If a dialog box appears asking you to restart Windows, you must restart Windows in 386 enhanced mode before you start the server software. . If you are running a LANtastic server, you cannot use Windows File Manager to format a floppy disk. You can use the format command at the MS-DOS prompt instead. .
