XP Network Protocols
Im
not going to explain everything about Protocols
that is way out of scope of this guide.
There
are three main Protocols : TCP/IP, IPX/SPX and
NETBEUI
TCP/IP
:
Is
automatically installed, can't be un-installed,
and is used by default for all networking functions.Windows
XP provides one other supported protocol -- IPX/SPX
-- and one unsupported protocol, NetBEUI.
By
default, XP configures TCP/IP to obtain an IP
address automatically. If there's a DHCP server
on the network, it will assign the IP address
and other TCP/IP settings to the connection. Otherwise,
Windows XP will use Automatic Private IP Addressing
to assign an IP address to the connection.
By
default, XP configures TCP/IP to obtain an IP
address automatically. If there's a DHCP server
on the network, it will assign the IP address
and other TCP/IP settings to the connection. Otherwise,
Windows XP will use Automatic Private IP Addressing
to assign an IP address to the connection.
This
default configuration should work, unchanged,
to connect a Windows XP computer to a network
that uses TCP/IP for File and Printer Sharing
in these common configurations:
Using
an Internet sharing program or a hardware router
protects the local area network from access by
other Internet users, so it's safe to use TCP/IP
for File and Printer Sharing on the LAN. The computers
have private IP addresses that aren't accessible
from the Internet. No other protocol is needed.
If
your network uses static IP addresses, click Use
the following IP address -- 192.168.0.3 and enter
the configuration information. For example, here
are settings for a network that uses a proxy server
at IP address 192.168.0.1 for Internet access.
IPX/SPX
If
the existing network uses IPX/SPX for File and
Printer Sharing, you can add that protocol to
the Windows XP computer. IPX/SPX is fully supported
in XP. In the connection's Properties, click the
Install button to add a network component. XP
will ask what type of network component to install.
Click
Protocol and Add.
Click
NWLink IPX/SPX/NetBIOS Compatible Transport Protocol
and click OK. Two NWLink items are added to the
connection's Properties
Have
your winXP CD handy.
NetBEUI
NetBEUI
was the default protocol in Windows 95, but Microsoft
has been moving away from NetBEUI ever since.
Starting with Windows 98, TCP/IP has been the
default protocol, and NetBEUI has been available
for installation as a supported protocol.
Starting
with Windows XP, NetBEUI is unsupported. This
doesn't mean that NetBEUI won't work! It means
that:
Microsoft
recommends against using it.
It
doesn't appear in the list of protocols that
can be installed.
Microsoft's
technical support staff won't answer questions
about NetBEUI or help solve problems with it.
Because it's been around for so long, some people
think that NetBEUI is required, and they install
it on all Windows networks. Actually, nothing
in Windows networking has ever required NetBEUI.
You can even un-install NetBEUI in Windows 95
and use a different protocol.
If
your existing network uses NetBEUI for File
and Printer Sharing, consider changing to a
different protocol. Most networks can safely
use TCP/IP. The main exceptions to this rule
are when:
All
of the networked computers are connected directly
to a cable or DSL modem and receive public IP
addresses from an Internet service provider.
You've
separated your LAN from the Internet, but you've
opened ports or have placed a computer outside
the firewall to use certain applications or
services.
If,
after considering all the options, you decide
to install NetBEUI on Windows XP, you can do
it using files on the Windows XP CD-ROM. Follow
the instructions in the article HOW TO:
Install NetBEUI on Windows XP in the
Microsoft Knowledge Base. These tips will help
with the installation process:
If
the Welcome to Microsoft Windows XP screen appears
when you insert the CD-ROM, click Perform additional
tasks followed by Browse this CD.
Where
the article refers to %SYSTEMROOT%, substitute
the name of the Windows XP installation folder,
which is typically C:Windows.
To
see the hidden INF directory, go to My Computer
| Tools | Folder Options | View. Scroll down
the list of Advanced settings, and un-check
Hide protected operating system files.
If you have a new computer that didn't come
with a Windows XP CD-ROM, see if the computer
manufacturer will send you the CD-ROM or the
necessary NetBEUI files. If that isn't possible,
you'll have to use a different protocol on your
network.
