-
- Start A Network
-
- Got a new portable? Don't shut the lid on your old one or sell it for a few
- bucks; network them instead, with your new machine as "Host" & the old one as
- "Client". Take advantage of the Hosts higher speed & fancy features; let the
- Client handle many of the peripherals [scanner, printer, zip drive, etc.]
- which will make your Host "portable" rather than tied down with several
- cables.
-
- "Buy" Insurance First
-
- BACK-IT UP!
- 1 - The Registry? YES
- 2 - Windows Folder? Recommended
- 3 - Entire System? Good Idea
-
- Cross Install
-
- If you run peripherals that you must always have access to, install them on
- both systems. Then re-connect them to the machine that will usually be their
- home. If problems occur on one machine, your much needed peripheral [e.g. zip
- drive] is available by just plugging it into the operable system followed by a
- reboot.
-
- Maintain Internet Access
-
- Don't try to set up your network in one fell swope on both systems. As you
- work on the installation & perfecting your settings, periodically check that
- at least one system has Internet Access even if you have to use a different
- modem or move the modem cable from one machine to the other temporarily. If
- Internet access is completely lost try restoring a Registry that existed when
- you had Internet access &/or re-installing TCP/IP. Also, have on hand a Free
- QNX Disk [http://www.qnx.com/demodisk/]. Internet Access with QNX does not
- depend on Windows; if you have only AOL as a way of getting on the Internet,
- QNX will not work, but at least AOL email, newsgroups & FTP are available.
-
- Documentation on Hand
-
- The WIN98SE manual has an entire section devoted to ICS & networking, but it
- is not comprehensive with details. Also download Microsoft Knowledge Base
- articles; here are a few which have links to more:
-
- 1- "Description of Internet Connection Sharing" at
- http://support.microsoft.com/support/kb/articles/Q234/8/15.ASP
-
- 2- "How to Troubleshoot Internet Connnection Sharing Problems" at
- http://support.microsoft.com/support/kb/articles/Q238/1/35.ASP
-
- 3- "Troubleshooting Windows 95/98 Network Connection Problems" at

-
- 4- "Description of How ICS Appears in Network Properties" at
- http://support.microsoft.com/support/kb/articles/Q236/4/65.ASP
-
- The Windows Help file has several "Trouleshooters" & Microsoft has an "Online
- Troubleshooter" [http://support.microsoft.com/support/tshoot/default.asp?FR=0]
- that can be helpful.
-
- Advice about Advice
-
- Your network setup may go very easily, and I am not trying to scare you, but
- some documentation, I have found, tends to be incomplete, gloss over vital
- details, conflict with other documentation & be down right wrong. One annoying
- habit is the failure to designate whether the advice pertains to the Host, the
- Client or both. Arm yourself with knowledge & fallbacks to avoid trouble as
- well as the ability to recover from it.
-
- Time Saving Shortcuts
-
- Put Shortcuts to "Network" & "Internet Options" on your Desktop. [You may be
- spending a lot of time there.] Open Control Panel, right click on each of the
- above items in turn & select "Create Shortcut." They will automatically land
- on the Desktop.
-
- Typical Hardware
-
- Hardware for a fully functional Network [i.e. file & printer sharing plus
- Internet access on both systems] includes PCMCIA Network Interface Cards
- [NICS] & Cables for each machine plus a Hub which handles the cables. Caution:
- Older portables may not support "Card-Bus" type PC Network cards [they may not
- even fit in the PCMCIA slot]; instead use a 16-Bit Network card for the older
- system. Another type of "simple" network is that done via "direct cable
- connection"; it is a file sharing network with a special cable that connects
- through both parallel or serial ports. It is relatively inexpensive, but the
- cable is short, full networking isn't available and usually laptops need their
- ports for printers, scanners, modems & other peripherals.
-
- Install Hardware
-
- The cables connecting the notebooks to a Hub can be a few feet or several
- feet, but before you start stringing cable around the house [& drilling holes
- through walls], get your network fully functional first. Place the notebooks
- back to back [especially handy if the hinges on the old machine are worn out]
- or side by side. The Network cards [that come with drivers & install
- instructions] for each machine set-up much like any PCMCIA card usually with
- "Plug-and-Play" ability.
-
- Software
-
- There are programs for sale to setup a network, but WIN98SE has all the
- software needed. If you've hidden the "Network Neighborhood" icon on your
- Desktop, it's time to bring it back to life -- use the Desktop tab in TweakUI.
- For the HOST to use file, print & Internet access sharing - DUN [Dial-up-
- Networking], TCP/IP plus ICS [Internet Connection Sharing] are required. The
- CLIENT does not [& should not] install ICS nor does the client need WIN98SE;
- an older O/S is fine. However, having the same O/S on both machines can have
- the advantage of one machine "bailing" the other out of trouble as well as
- minimizing the time it takes to download "updates/patches" from the Internet.
- [WIN98/WIN98SE can be "forced" onto many older laptops; see: Special WIN98
- Update at http://user.aol.com/ojatex/win98.htm]
-
- Network Settings & Troubleshooting
-
- A. Ideally, the NICS come with detailed instructions on setting up the file
- and print sharing functions for each version of Windows they support. Before
- you buy the NICS, inquire about the instructions & support that is available.
-
- 1. Both the Host & the Client's Network Dialogue Screen should show 'Client'
- entries for "Client for Microsoft Networks" & 'Service' entries for "File and
- Printer Sharing for Microsoft Networks". If any of these items are missing
- install them with the 'Add' Button. Click on the 'File & Print Sharing'
- button in the Network Dialogue Screen on both machines in turn; make sure
- both the File & Printer sharing items are checked.
-
- 2. From the "Identification" tab in the Network Box [for both the Host &
- Client], enter a 'Computer name' of your choice; in the 'Workgroup' entry,
- make sure that the same name is used on the Host & Client machines.
-
- 3. Confirm that 'File & Printer Sharing' is activated by opening the Network
- Neighborhood icon on both the Host & Client machines in turn. Each machine
- should show an icon for both the Host & Client by their respective 'Computer
- names'.
-
- 4. On both machines in turn, open 'My Computer", right click on each drive
- that you want to share & select 'Sharing'. Under 'Share Name', fill in a
- descriptive identity. [For example, when working on the Host machine where
- the Hard drive is to be shared, fill in the 'Share Name' box with "Host
- C:/".] In the "Access Type" box select what type of access the other machine
- is allowed. To share a specific printer, on the system to which the printer
- is connected, open the Printer icon, right click on the Printer to be shared,
- select 'Sharing', click on the "Shared as" item & fill in the 'Share name'
- box with the printer's name if it is not already named.
-
- 5. On both machines in turn, re-open Network Neighborhood, click on the
- 'Computer Name' icon of each machine to view the folders representing the
- shared drives/folders. On the machine which does not have a connected
- printer, open the icon of the machine to which the printer is connected,
- click on the printer icon which will enable the Share Printer Wizard; go
- through the wizard screens to enable use of the printer.
-
- Optional: After sharing is set-up, you may want to "map" the various drives
- [on both the Host & Client] & printer by right clicking on the folders in
- Network Neighborhood. See the Windows Help file for details about mapping
- Network Drives & Printers.
-
- B. If not already present, install ICS on the Host computer using the Windows
- Setup Tab in "Control Panel/Add-Remove Programs". ICS is successfully
- installed on the Host when there is in the Network Dialogue Box the following
- items:
-
- 1. A TCP/IP protocol entry identified as <Home> [Also look under Properties/
- Bindings for the Network Adapter {the NIC} item to contain a checked entry
- for TCP/IP <Home> & a checked entry for Internet Connection Sharing
- <Protocol>].
-
- 2. A TCP/IP protocol entry identified as <Shared> [Also look under
- Properties/Bindings for the Dial-Up Adapter item to contain a checked entry
- for TCP/IP <Shared> & a checked entry for Internet Connection Sharing
- <Protocol>].
-
- 3. A TCP/IP protocol entry pointing to Internet Connection Sharing [Also look
- under Properties/Bindings for the Internet Connection Sharing Adapter to
- contain checked items for TCP/IP & Internet Connection Sharing <protocol>].
-
- 4. If there are missing or incorrect entries in items in B1, B2 &/or B3
- above, consult "How to Troubleshoot Internet Connnection Sharing Problems"
- mentioned above. Also open the "Internet Options" shortcut [Connections tab]
- on the Host, select the "Sharing" button; the 'Enable Internet Connection
- Sharing' box should be checked, the 'Connect to the Internet using' box
- should show "Dial-Up Adapter" & the 'Connect to my home network using' box
- should show the name of your Network Adapter Card [NIC].
-
- 5. Once the Host's Network Dialogue box contains the properly configured
- TCP/IP entries & required reboots made, test the Host's ability to access the
- Internet via the browser or other application that is used to go online.
-
- C. Once establishing the Host's ability to access both the Client's files &
- the Internet with ICS installed, run the ICS floppy disk on the Client
- machine.
-
- 1. On the Client, open the Network shortcut; there should be a protocol entry
- for TCP/IP pointing to Network Adapter [NICS]. Also, select the 'Properties'
- button for this TCP/IP protocol which should have activated/checked:
-
- a. IP Address tab as "Obtain IP address automatically".
-
- b. WINS tab as "Use DHCP for WINS".
-
- c. Gateway tab with no entries.
-
- d. DNS tab as "Disable DNS".
-
- e. NetBIOS tab with no entries.
-
- f. Bindings tab with both "Client for Microsoft Networks" & "File and
- Printer Sharing" checked.
-
- 2. After any necessary changes & reboots by the Client, have the Client
- determine whether Internet access is available on their machine. Be sure that
- the Host system is active [i.e. Windows running, signed onto Network, not in
- a standby mode, Modem turned on]. If Internet access fails on the Client, try
- the following [for items #a through #d below be sure the Host is connected to
- the Internet]:
-
- a. From Start/Run on Client, type in "winipcfg" [no quotes]. Select "Release
- All", "Renew All" and "Okay". Reboot Client & attempt Internet access.
-
- b. From a DOS prompt [C:>Windows] type "ping 192.168.0.1" [no quotes], hit
- enter to establish packets sent by the Client are received by the Host with
- 0% loss.
-
- c. From the Client, ping the IP address in the same manner as item #b. [If
- the IP address is unknown, use the Host machine to ping the IP Host name
- (such as "www.myispname.com" {no quotes} where myispname is the company from
- which you obtain Internet access). Pinging the IP Host name will return the
- IP address in a numeric form]. Packets sent from the Client to the IP
- address [numeric form] using the ping command should be received with 0%
- loss.
-
- d. From the Client, ping the IP Host name. Packets sent from the Client to
- the IP Host name using the ping command should be received with 0% loss. If
- pinging the IP Host name is successful, try pinging other websites, such as
- "www.zdnet.com" [no quotes] & "www.pcworld.com" [no quotes]; make a note of
- the IP addresses [numeric form] for these websites if packets sent from the
- Client machine are received with 0% loss. On the Client machine, open the
- browser, type in the Address Bar the IP name of a successfully pinged
- website such as "http://www.zdnet.com" [no quotes]. Next type in the Address
- Bar: "http://xxx.xxx.xxx.xxx" [no quotes] where xxx stands for the the IP
- address [numeric form] of a successfully pinged website. If the Client's
- browser cannot display the website of a successfully pinged website, check
- that the browser is set to operate via a LAN & no proxy server is enabled.
-
- e. See "DUN Client May Not Be Able to Ping Remote Host by Name" at
- http://support.microsoft.com/support/kb/articles/q160/0/95.asp. If changes
- were made to the Client's configuration, reboot Client & attempt Internet
- access.
-
- f. On the Client's machine, access the Registry [Start/Run, type "regedit"],
- go to key: "HKLM\System\CurrentControlSet\Services\Class\Net", back it up,
- open all the numbered keys [0000, 0001, 0002, etc.], delete any & all
- numbered keys that have a "DeviceDesc" string where the value is NOT the
- name of the Client's Network Adapter [NIC] as listed in the Client's Network
- Dialogue screen. Reboot Client & attempt Internet access.
-
- g. On the Client's machine, right click on "My Computer", select
- 'Properties' and the 'Device Manager' tab. From the 'View Devices by Type'
- mode, expand the 'Network Adapter' icon, remove any adapter that is NOT the
- Client's Network Adapter [NIC].
-
- h. Remove, then re-install TCP/IP from the Network Dialogue screen on the
- Client's machine. The re-installed TCP/IP protocol on the Client should be
- configured as outlined in item #C 1 a through f above. Reboot Client &
- attempt Internet access.
