Hi I have a computer with an MSI motherboard with a built in ethernet card.
I have another PC and an old laptop connected together via a Netgear hub.
When the network was set up the computer with the built in Via Rhine card
was set up with an IP address of 192.168.0.1 i.e. in the TCP/IP properties
specify an IP address was selected and 192.168.0.1 entered.

Due to a cock up the card was uninstalled along with the software and then
re installed. At that time the previous information (i.e. specify an
address) was not known and on re configuring the network 'Obtain an IP
address automatically' was selected. This computer was unable to see or be
seen by the other 2 computers. On investgation the IP address allocated was
found to be 169.254.239.115

After much headscratching and because the computer is dual booting and
worked with one OS and not the other, it was discovered that if an IP
address was obtained automatically in either or both OS then the network
failed with that OS.

In other words, immaterial of the OS selected, if the IP address was
selected automatically the IP address became 169.254.239.115 and the
computer could not communicate. The only way to resolve the problem is to
manually specify an IP address in the range 192.168.?.?

Should the network function with an IP address in the range 169.254.239.*
and if not why is that IP address being selected.?

I know I could just carry on as before but I would like to understand what
is happening.

Thanks Ron

Did you need to start a new thread?

Did you read my last reply, you didn't answer several of the questions I
asked.

I get confused when I switch between the operating systems as they are set
up slightly different in the way they display messages in Outlook Express.

And to answer the question why do I need two operating systems? Canon lbp
460 printer. And if you say you can get it to work with Windows XP Pro YOU
CAN'T.

What were the questions? I thought I answered them in this new post.

Did you check the computer (NetBIOS name) and DNS host names are the
same?

Did you check ipconfig/all for 98/XP gives the same MAC address?

Do you have a second NIC, can you install 1 to work under 98 and the
other only under XP, this may be a pain swapping the cable. But in
XP/NT/2000 it's possible to disable specific hardware. Hence 2 cables
can be connected at the same time as the hardware is disabled for each
alternative OS. Don't know about 98 and doing this.

If it's a DSL/Cable Modem maybe pressing the reset button/power off-on
after booting between 98/XP will be okay.

If XP/98 show different MACs from ipconfig do you have to register the
different MAC with your ISP, normally you are only allowed one.

Some NIC drivers allow soft setting of the MAC address, check the NIC
properties , Advanced options.

My XP box is off, so a Win 2000 example will have to do -

Start / Settings / Control Panel / Network & Dial Up Connections / Local
Area Connection / right click select Properties / look for the NIC
hardware (not TCP/IP or other settings) / Configure / Advanced / Locally
Administered Addresses.
Normally this should be blank, i.e. don't override the built in MAC
address. Another pet hate of mine at work :-)
What you could try is on 98 make this the same value as XP.

If you have the other PCs all turned off do you still get the problem?

My ISP recommends removing routers to debug problems. Basically with the
setup I choose my router spoofed (pretends to look like the MAC address
of the NIC) the ISP registered address. I can pull the CM lead from the
router , put it in the PC NIC , reboot and the PC gets the ISP settings
directly.

If you can do this, for both 98/XP do they then still get the same
values from the ISP. Again between changes reboot your DSL/CM box.

yes

yes

not at the moment

VIA RHINE ethernet card built into MSI MS6738 motherboard

Not Applicable

Yes

Not connected via ISP

This is a home network to connect 2 PCs and a laptop(because I have a 5 port
hub and three cables and the laptop has a network card built in) so that I
can use a scanner which requires an ISA slot therefore computer number 1
(win 98)which is old and my new computer which does not have an ISA slot but
dual booting so I can use a Canon printer.

To get back to my original question(I think) why when I allow my computer to
pick its own IP address, does it pick an address that will not work? i.e. if
the IP address is 169.254.239.115 when I run ping 169.254.239.115 it cannot
reach that address but when I manually enter 192.168.0.1 as its IP address
it works. And this is in both operating systems

Ron

SORRY ping from another computer on the network

it cannot reach that address but when I manually enter 192.168.0.1 as its IP
address

Fine, I didn't recall the non ISP/standalone being mentioned before, and
192.168 is a common allocation for routers used at home.

Did you read, from earlier
http://www.webopedia.com/TERM/A/APIPA.html
or even search to find other info
http://www.duxcw.com/faq/network/autoip.htm
or even search to disable the feature.

Ok, if you manually set some PCs to 192.168 with whatever subnet mask
only PCs on the same IP range/mask can talk to each other.

If everything is allowed to / can use autoconfigure it will work.

Subnetting information.

This does not stop disparte networks i.e. 2 PCs 192.168 and 2 PCs
169.254 being on the same cable. But only the 192 or 169 PCs can talk
to PCs on the same IP range. Without a router, the 192/169 PCs will
never see each other.

You have to either manually configure everything on 192.168 or allow
everything to auto configure on 169.254. as per the previous
http://www.webopedia.com/TERM/A/APIPA.html

What you are getting is
A PC on 169.254.x.x / mask 255.255.0.0 for a default class B.
and the rest 192.168.y.y / mask (default)255.255.255.0 is for Class C.

There's a good project for you, get another PC with 2NICs and configure
it as a router.
