[Mike]

Chuck,

managed to enable DHCP, reran Ipconfig and what do I get ??

IP address on the laptop : 169.254.29.66 (!!!!!) I hate it.
Subnet mask : 255.255.0.0, different from the host's ( desktop)

Mike

Mike,

Network Connections - LAN Properties - TCP/IP Properties - Check both "Obtain an
IP address automatically" and "Obtain DNS server addresses automatically".

Then post the new IPConfig.

OK, Mike,

ICS is NOT working. Go to bed. Work on this tomorrow.

Post the IPConfig complete, maybe a clue there.

Mike,

I don't know what to make of this IPConfig. IP address "192.254.x.x" makes NO
sense. It should be either "169.254.x.x" or "192.168.x.x". Are you copying /
pasting the IPConfig, or typing it by hand? If "169.254.x.x", ICS is clearly
not working.

When you ran the network setup wizard (causing you to have to then delete the
fscking bridge), did you select BOTH "This computer connects directly to the
Internet" AND "This computer provides service to other computers"?

If ICS IS running on Desktop, and DHCP is enabled on Laptop, then there has to
be a physical connection problem. You said that checked the cable - how did you
do that?

Cheers,
Chuck

[Mike]

1) I was copying / pasting the IPconfig
2) I selected "This computer connects directly to the Internet" for the
desktop. Did NOT see the other option.
3) I reran the wizard on the laptop five minutes ago from the Windows CD
this time ( "This computer connects through another computer"............ )
and a bridging was established between the LAN and the 1394 connections. I
deleted the bridge, set up DHCP and automatic IP addressing and now the
values are ( copied AND checked ) :

DHCP enabled : yes
Autoconfig enabled : yes
Autoconfiguration IP Address : 169.254.29.66
Subnet mask : 255.255.0.0
Default gateway : blank

4) I checked the cable at work, by transferring files between one PC and
another and all worked fine. No snags.
Waiting for inputs. Wonder if we'll ever get on top of this
problem................ Sigh.

Mike

Mike,

Having run the wizard and selected "This computer connects through another
computer", do you have internet service on Desktop? If not, you'll have to
rerun the wizard, and select "This computer connects directly to the Internet".
Please don't try both options - only one will work. Use that option.

Having setup, and verified, internet service on Desktop, delete the bridge yet
again.

Make sure DHCP is enabled on the CNet adapter on Desktop (Local Area Connection
- Properties - TCP/IP - Properties).

Go back to Local Area Connection - Properties, and select the Advanced tab. If
ICS is possible, you should have an option "Allow other network users to connect
through this computer's Internet connection".

If ICS is not an option under Advanced, then we have to figure out why.

Cheers,
Chuck

I used the second option on desktop

Having setup, and verified, internet service on Desktop, delete the bridge
yet
again.

Internet works on Desktop. Bridge was deleted
on LAPTOP

Make sure DHCP is enabled on the CNet adapter on Desktop (Local Area
Connection
- Properties - TCP/IP - Properties).

To enable DHCP I had to revert to automatic
IP addressing. Now enabled

Go back to Local Area Connection - Properties, and select the Advanced
tab. If
ICS is possible, you should have an option "Allow other network users to
connect
through this computer's Internet connection".

NO such option in the Advanced tab. Only "
Windows firewall" and related settings. Does it make a difference,
as far as this setting is concerned, if the network cable is now temporarily
disconnected from the laptop ( my son is
playing Doom3 ) ? It shouldn't, right ? If needed I'll reconnect the laptop.

If ICS is not an option under Advanced, then we have to figure out why.

Funny, if I force DHCP on desktop and therefore automatic IP addressing and
DNS server address, I get a bunch of zeros for BOTH IP address and Subnet
mask and a DHCP server of 255.255.255.255. The LAN icon in the taskbar says
"Limited or no connectivity". Same icon in laptop shows no problems but IP
address is still 169.254.29.66.
Any ideas ??

Mike,

The Help Center references to ICS (Start - Help - "ICS") state that ICS
requires, minimally, two connections (including one modem) on your computer.
Another computer actually connected is not required.

Here are several websites, with tutorials, which may help:
http://www.cablesense.com/
http://www.homenethelp.com/
http://www.practicallynetworked.com/

Does your modem (dialup connection) show under Network Connections?

Chuck,
yes, I have the ADSL connection listed in the Network connections ( Internet
connections section ). Please consider what I wrote in my last message, i.e.
if I force DHCP on desktop and therefore automatic IP addressing and DNS
server address, I get a bunch of zeros for BOTH IP address and Subnet mask
and a DHCP server of 255.255.255.255. The LAN icon in the taskbar says
"Limited or no connectivity". Could I have a corrupted TCP/IP stack ?? I've
heard about this possible occurrence.
Same icon in laptop shows no problems but IP address is still 169.254.29.66.

address is still 169.254.29.66.

If you leave DHCP on on Desktop, as soon as ICS is enabled, the address will
change to 192.168.0.1. Til then, it shouldn't matter as far as internet service
goes.

If you want to do file sharing until then, enable DHCP (General tab) and APIPA
(Alternate tab), on both computers. They'll both get APIPA addresses, which
will enable them to connect to each other.

However, you won't have internet service on Laptop until either:
1) You get ICS working.
2) You get a router and connect both computers to the router.

Mike,

Section "Method 1:" in the Microsoft document should explain the 000.000.000.000
etc:
<http://support.microsoft.com/default.aspx?scid=kb;en-us;314067#10>

Until you get ICS working, both the desktop and laptop should be 169.254.x.x, or
000.000.000.000.

I guess it wouldn't hurt to check LSP and TCP/IP. Also, since you'v eliminated
the cable as a problem, check the network cards. They should have diagnostic
procedures, read their documentation.

LSP-Fix and WinsockLSPFix will fix corrupted LSP (a small part of TCP/IP).
<http://www.cexx.org/lspfix.htm>

To fix corrupted TCP/IP, open a command window (Start - Run - "cmd"). Into the
open window, at the prompt, and type "netsh int ip reset c:\netsh.log".

If you leave DHCP on on Desktop, as soon as ICS is enabled, the address
will
change to 192.168.0.1. Til then, it shouldn't matter as far as internet
service
goes.

The wizard on desktop forces a manual IP address of 192.168.0.1, the
connection is not labeled "Limited or no connection", but then no DHCP is
available. If I change to automatic then I get a bunch of zero's in the
addresses and the connectivity is flagged as not working.

If you want to do file sharing until then, enable DHCP (General tab) and
APIPA
(Alternate tab), on both computers. They'll both get APIPA addresses,
which
will enable them to connect to each other.

However, you won't have internet service on Laptop until either:
1) You get ICS working.
Agreed

2) You get a router and connect both computers to the router.

The connection was working fine with just the crossover cable.

Mike,

From a curiosity view, I intend to keep on this as long as you, and find out why
ICS can't be started on Desktop. I'll see if I can dig up some other ICS
diagnostic references.

From a practical view, I have to recommend that you get a router to share
internet service and protect your network. Even if you can get ICS working, and
especially if you can't.

You have broadband, and 2 computers. Connecting the two computers with a router
is the responsible solution.

All computers will be safer. The router will block any malevolent internet
traffic. This further protects the internet, from your becoming infected and
spreading the infection.

All computers will run better, with the router blocking the trash infection
traffic that is most likely hitting Desktop. Any personal firewall on either
computer will have less to do, because the router will block most malevolent
traffic.

All computers will run independent of each other. Right now, if you ever get
ICS working, you will have to have Desktop on whenever you wish to access the
internet from Laptop. With a router, this will not be true.

If you can afford to have more then one computer, and broadband, you can afford
a router. For many reasons.

I'll note further that, if we hadn't realised that you are running broadband
internet, without a router, this far down in the thread, you would have had
other folks telling you just this: Please get a router. Some would be a bit
ruder than I am.

Cheers,
Chuck

Chuck,

it works now !!!!!!!!!!!!!
It was a defective LAN card on desktop.
I replaced it with one I borrowed at work and now I have both ICS and File Sharing !!!
Thanks for all the help and sorry if I frustrated you in the long run !!

Mike
