- Overview of Windows Sockets
- ---------------------------
- Microsoft TCP/IP includes support for Windows Sockets on Microsoft Windows
- and Workgroups for Windows workstations. A socket provides an end point to
- a connection; two sockets form a complete path. A socket works as a
- bi-directional pipe for incoming and outgoing data. The Windows Sockets API
- is a networking API tailored for use by programmers using the Microsoft
- Windows operating system. Windows Sockets is a public specification based
- on Berkeley UNIX sockets and aims to:
-
- * Provide a familiar networking API to programmers using Windows or UNIX.
- * Offer binary compatibility between heterogeneous Windows-based TCP/IP
- stack and utilities vendors.
- * Support both connection-oriented and connectionless protocols.
-
- If you are running an application that uses Windows Sockets, be sure to
- enable Windows Sockets when you configure Microsoft TCP/IP. If you are
- unsure whether any of your applications use Windows Sockets, refer to the
- documentation included with that vendor's application.
-
-
- Setting DNR and Sockets Settings
- --------------------------------
- If you specify the MS TCP/IP protocol during setup, you will now see an
- additional dialog box after you have used the Advanced button in the
- MS-TCP/IP Configuration dialog box. This new dialog box, DNR and Sockets
- Settings, is used only if your MS TCP/IP network has a domain name service
- (DNS) server. If your network has a DNS and you choose to configure the
- Domain Name Resolver (DNR) parameters, the DNR module will be loaded with
- your sockets and Telnet applications to resolve hostname-to-IP address
- mappings. This allows you to specify remote computers by computername
- without knowing specific IP addresses. If you use this dialog box, these
- are the values you will need to supply:
-
- Username
- Your username.
-
- Hostname
- The computername your workstation will report when using the remote
- services. The default is your LAN Manager computername.
-
- Primary Nameserver IP Address
- The IP address of the DNS server you want the DNR to consult first when
- resolving computername-to-IP address mappings.
-
- Secondary Nameserver IP Address
- The IP address of the DNS server you want the DNR to consult when
- resolving computername-to-IP address mappings if the request to the
- primary nameserver fails.
-
- Domain Name Suffix
- The suffix appended to any computername for DNS processing. Your network
- administrator can tell you what to enter here.
-
- Enable Windows Sockets
- Mark this checkbox if you want Sockets to be invoked from the
- AUTOEXEC.BAT file.
-
- Number of Sockets
- The maximum number of sockets that can be made available to applications
- at any one time. The range is 1 to 22 sockets.
-
- Note: Some applications may use more than one socket to provide a service.
- Consider this when trying to maximize available memory. The total
- number of sockets and NetBIOS sessions combined must not exceed 22.
-
-
-
- If Microsoft RPC Is Installed
- -----------------------------
-
- If Microsoft Remote Procedure Call (RPC) is installed on your system,
- you must copy RPC16C3.DLL from the \DRIVERS\PROTOCOL\TCPIP directory of
- the DOS DRIVERS 2 disk to your WINDOWS\SYSTEM directory in order for
- Windows Sockets to work properly with Microsoft TCP/IP.
-
-
- Using Windows for Workgroups and the Remote Access Service (RAS)
- ================================================================
-
- Installing Windows for Workgroups 3.1
- -------------------------------------
-
- If you plan to connect to the network using only Remote Access and a modem, click
- the Cancel button when Windows for Workgroups Setup prompts you for the type
- of network adapter you have. Windows for Workgroups will give you several
- warning messages informing you that network functionality cannot be provided
- without network adapters. Disregard these messages if you plan to install
- Remote Access later. The Remote Access Setup program installs the device
- drivers required by Remote Access.
-
- Note
- If you plan to use a network adapter card and Remote Access at the same
- time, install the appropriate Windows for Workgroups network drivers.
-
-
- Installing RAS on a Workstation Configured for both
- LAN Manager and Windows for Workgroups
- ---------------------------------------------------
-
- Remote Access files are installed in your Windows for Workgroups directory
- by default if the directory is present in your path. If you want Remote
- Access to be installed in the LAN Manager directory on a computer that has
- valid installations of both LAN Manager 2.2 and Windows for Workgroups,
- temporarily delete the Windows for Workgroups directory from the path
- statement in the AUTOEXEC.BAT file and reboot the computer before running
- Remote Access Setup.
-
- After RAS has been installed, be sure to replace the Windows for Workgroups
- directory in the path statement in the AUTOEXEC.BAT file.
-
-
- Windows for Workgroups and MS-DOS Workgroup Connection
- ------------------------------------------------------
-
- If you are running Windows for Workgroups or MS-DOS Workgroup Connection,
- you do not need to install LAN Manager before installing Remote Access.
-
- No references to rasload apply to installations running Windows for
- Workgroups or MS-DOS Workgroup Connection. To load the Remote Access
- service, run Remote Access Setup. For instructions about running Setup,
- see the Microsoft LAN Manager Remote Access Service AdministratorÆs Guide.
-
-
- Not Enough Memory for Setup
- ---------------------------
- If you don't have enough memory to install Remote Access service by running
- Setup on the Remote Access Setup disk, you can install it with wfwsetup for
- Windows for Workgroups and MS-DOS Workgroup Connection, or lmrsetup for
- LAN Manager. This procedure requires about 35 kilobytes (K) less random
- access memory (RAM).
-
- To run setup this way, insert the Remote Access Setup disk into drive A,
- and follow the appropriate step:
-
- * From the Windows File Manager, change to drive A and click
- WFWSETUP.EXE or LMRSETUP.EXE, whichever applies.
- * From the command line, type
- a:wfwsetup
- Or type
- a:lmrsetup
-
-
- Avoiding the Delay from Browsing Domains
- ----------------------------------------
- When you click the Connect Network Drive button on the Windows for
- Workgroups File Manager, all domains on the network are browsed. When
- accessing the network through the Remote Access Service, browsing all
- domains can cause an unwanted delay if you already know what share you
- want to connect to. To avoid browsing and therefore eliminate the delay,
- follow these steps:
-
- 1. Connect to the share from the command line by typing the net use
- command followed by the drive letter, server name, and share name. The
- syntax is:
- net use x: \\servername\sharename
-
- 2. Once you've connected, refresh the File Manager display to see the
- drive letter you assigned to your share. To refresh the display, pull down
- the Windows menu and click Refresh, or press the F5 key.
-
-
- Reinstalling Remote Access
- --------------------------
- You must remove and then reinstall Remote Access Service, using Setup,
- under the following circumstances:
-
- * If you are running Windows for Workgroups or MS-DOS Workgroup
- Connection and you encounter problems relating to configuration files.
-
- Note: In this case, error messages that refer to LAN Manager
- configuration files do not apply. However, error messages dealing
- with Remote Access configuration files, modem errors, and so on
- still apply to both Windows for Workgroups and MS-DOS
- Workgroup Connection.
-
- * If you upgrade from MS-DOS Workgroup Connection to
- Windows for Workgroups.
-
-
- Modifying Configuration
- -----------------------
- To modify the Remote Access configuration:
-
- Platform Procedure
-
- Windows for Workgroups Click the Remote Access icon on
- the control panel.
-
- MS-DOS Workgroup Connection Run Remote Access Setup from
- the DOS\RAS directory.
-
- To save RAM, both VCOMMIOD.EXE and WANTSR.EXE can be loaded high, assuming
- you have a configuration that allows terminate-and-stay-resident (TSR)
- programs to be loaded high. Find the following lines in your AUTOEXEC.BAT
- file:
- C:\WINDOWS\ras\vcommiod.exe
- C:\WINDOWS\ras\wantsr.exe
-
- Change them to:
- loadhigh C:\WINDOWS\ras\vcommiod.exe
- loadhigh C:\WINDOWS\ras\wantsr.exe
-
-
- Using NetBEUI
- -------------
- If you are using both NetBEUI (to use the local network) and RAS (to access
- a remote network), you need to be using the real mode version of NetBEUI
- rather than the protect mode version that is normally loaded when the
- Windows operating system is started. To use the real mode version, issue
- the command net start netbeui before starting the Windows operating system.
- If your local network does not require the NetBEUI protocol, this is not a
- problem.
-
- The real mode NetBEUI will take up space in the real mode stack. If this is
- a problem, you can disable RAS and allow the protect mode NetBEUI to be
- loaded when the Windows operating system is started. This will allow you
- to use the local network, but not RAS. To use RAS again you must re-enable
- RAS and then either explicitly load NetBEUI before starting the Windows
- operating system or not use local area network resources that require the
- use of NetBEUI. You can disable RAS from within Windows or from the
- command line.
-
- * To disable RAS from within the Windows operating system
- 1. Choose the Remote Access icon from the Control Panel.
- 2. Clear the Enable Remote Access checkbox.
- 3. Reboot your computer.
-
- * To disable RAS from the Command Line
- 1. Go to the RAS subdirectory of the WINDOWS directory by
- typing a command such as cd c:\windows\ras.
- 2. Start the RAS setup program by typing setup.
- 3. Clear the Enable Remote Access checkbox.
- 4. Reboot your computer.
-
-
- Using Modems with Advanced Features
- -----------------------------------
- If you have a modem that can do hardware data compression, or supports
- speeds above 19.2K baud, use the alternate modem configuration file that
- enables these advanced features. The file is MCOMP.INF. Use the following
- procedure to access advanced modem features.
-
- * To use the advanced features of the modem:
- 1. Insert the Remote Access Setup disk into drive A.
- 2. Go to your Windows directory if you are using Windows for Workgroups,
- or to your LAN Manager root directory.
- 3. Rename the MODEMS.INF file to a temporary filename such as MODEMS.OLD.
- 4. Copy the new file using the following command:
-
- copy a:mcomp.inf modems.inf
-
- 5. Run the RAS Setup program again and select the your modem from the
- list of modems.
-
- If the modem does not appear in the list of modems, the advanced
- features are not supported on that particular modem. In this case,
- exit RAS Setup copy MODEMS.OLD (or whatever you renamed it to) back
- to MODEMS.INF and run the RAS Setup program again to select the
- appropriate modem.
-
- 6. Exit RAS Setup and reboot the computer.
-
-
- Creating New Modem Sections
- ---------------------------
- When creating new modem sections, be sure to
- * set the modem to always report DTE speed (port to modem speed)
- instead of the DCE speed (modem to modem speed)
- * set modem to NOT report negotiation progress.
-
-
- Turning Compression On or Off
- -----------------------------
- The following modems should turn off compression when connecting to OS/2
- based RAS 1.x servers, and turn on compression when connecting to NT base
- RAS servers.
- * Codex 3220 Plus
- * Codex 326x FAST series
- * US Robotics Courier modems
- * UDS 3229
-
-
- DSI 9624LE Modems
- -----------------
- The DSI 9624LE modem will only work when connected at high speed (9600 baud
- or greater). Do not use this modem if connecting at 4800 or lower speed.
-
