1.0 General Notes . There are many settings in the SYSTEM.INI file that affect the way Windows interacts with a network. You can change these settings to correct most problems you might have operating Windows with your network. See the SYSINI.WRI online document for information about changing the following SYSTEM.INI settings: [Boot] Network.drv= [Standard] Int28Filter= NetHeapSize= [386Enh] AllVMsExclusive= EMMExclude= FileSysChange= InDOSPolling= Int28Critical= NetAsyncFallback= NetAsyncTimeout= NetDMASize= NetHeapSize= Network= PSPIncrement= ReflectDOSInt2A= TimerCriticalSection= TokenRingSearch= UniqueDOSPSP= . Many networks require the TimerCriticalSection entry in the [386Enh] section of the SYSTEM.INI file to be set to a value of 10000 or greater. For more information, see the SYSINI.WRI file. . The default value for the NetHeapSize entry in the [Standard] section of the SYSTEM.INI file is 8K. Although some applications require this value, in most cases you can decrease the value to 4K in order to increase the amount of memory available to your applications. A few applications require the value to be 4K. . If for some reason you use Setup to change your network configuration after you have already set up Windows, Setup might not remove all support for your previous network selection. Unnecessary files might be left in your Windows directory, and entries might be left in your WIN.INI or SYSTEM.INI files that could harm your system's performance. If you change your network configuration, check the notes about both your previous and new selections to see if any previous entries are no longer required. . Some network adapter cards require the ExcludeHighRegion (or EMMExclude) entry in the [386Enh] section of the SYSTEM.INI file to be set to the memory range used by the card. For more information, see your network-adapter documentation and the SYSINI.WRI file. These cards may also require an X= option on the EMM386 command line in your CONFIG.SYS file. For more information, see chapter 14, "Optimizing Windows," in the Microsoft Windows User's Guide. . Some network cards and some network transport stacks require special handling. Consult the following sections not only for the manufacturer of your network but also for the manufacturer of your network adapter and your transport stack. . Many networks have pop-up message facilities that allow you to see messages sent from other servers or workstations. In most cases, these pop-up programs will cause Windows Setup to fail if a message is received while setting up. Many networks provide additional utilities that allow them to work with Windows once Windows is set up, but these are generally not available during Setup. You should make sure any such pop-up service is disabled before setting up Windows. Please consult specific entries regarding your network in the following sections, or consult your network documentation for instructions. . If you configured your remote-boot workstation to run Windows version 3.0, you may be loading a program called RIPLMEM.EXE or RPLMEM.EXE in your AUTOEXEC.BAT. This program is no longer required for running Windows version 3.1. . The Windows Resource Kit for the Microsoft Windows Operating System Version 3.1 contains additional information about setting up and configuring Windows for use with a network, and information for system administrators. This kit provides complete technical information about Windows version 3.1 for the support professional. It includes a technical reference manual, and a disk containing helpful utilities, system resource viewers, drivers, and accessories. To order the Windows Resource Kit within the United States, dial: 1-800-642-7676 To order outside of the United States, dial the phone number for your area. You can find this number on the International Subsidiary card. . If you are running a shared copy of Windows from a network drive, make sure both your personal Windows directory and the shared network directory are included on the PATH command line in your AUTOEXEC.BAT file. . If you receive sharing violations while running a shared copy of Windows, make sure that all of the files in the shared network directory are marked as read-only. . If you have problems running a shared copy of Windows, remove the MS-DOS SHARE command from your system. With some networks, the MS-DOS SHARE utility must not be loaded on a workstation to run a shared copy of Windows. . If you have problems and your network software is loaded high (in the upper memory area between 640K and 1 MB), try loading the network in conventional memory. . Windows Print Manager spools print jobs to the location specified by the MS-DOS environment variable TEMP. If TEMP is not set, Print Manager will use the root of drive C. For diskless workstations, set the TEMP variable either to a RAM disk or to the location of a network directory (you must have full access to this directory). The TEMP variable may be set by placing a SET TEMP= statement in the AUTOEXEC.BAT file or network login script. For example, to spool to the network directory X:\USERNAME\WINUSER\TEMP, you would use the statement SET TEMP=x:\username\winuser\temp. Each user must have a personal TEMP directory. . On some diskless workstations, you will not be able to start Windows in standard mode unless you have a TEMP environment variable set or you have added a swapdisk entry in the [NonWindowsApp] section of the SYSTEM.INI file. For more information about the swapdisk entry, see the SYSINI.WRI file. . If you are running a peer-to-peer network, you may not be able to format a floppy disk by using File Manager. You can use the format command at the MS-DOS prompt instead. . Some networks ship with their own copies of files that are included with Windows version 3.1. Usually Windows includes a newer version, and upgrades the one provided with the network when you run Setup. However, if you install the network after installing Windows 3.1, some network installation programs will overwrite the newer file provided with Windows with their own, older version. This older version may lack features provided in the newer version, or it may not function properly with Windows 3.1. You should back up your network and Windows files before upgrading your network software. If problems occur, you may need to restore the previous version of some files. .
