Network IP address

[NCBill]

I am running a two computer network with a DSL line ported into the host
computer through a USB port and the two machines connected by an
ethernet crossover cable. The network has quit functioning and when I
click on "repair" for this connection in the network window, I get a
message that says Windows cannot repair because it can't renew the IP
address - for assistance ask the network manager. Well, I AM the
manager, and I don't know how to set the IP address.

For this connection, I clicked on properties/configure(the ethernet
adapter)/advanced/network address. There it shows "not present" has
been selected. Should I select a value, and if so what value? The
ethernet adapter is a GVC Realtek PCI.

I presume you're using ICS on the computer connected to the DSL modem via
USB?
What do you mean by "the network has quit functioning"? If you're using ICS,
the host computer acts as a DHCP server and is supposed to give the client
computer an IP address...check the event logs on the host computer.

Personally, I hate ICS - I'd get a cheapo gateway appliance that can handle
USB connections to the modem if there's no Ethernet port on the LAN side -
and let it do DHCP, NAT.

Bill,

First, check the client computer for a Winsock problem.
http://support.microsoft.com/?id=318584
http://support.microsoft.com/?id=811259

If it's running XP SP2, Start - Run - "cmd", and type "netsh winsock reset
catalog" into the command window.

Give LSP-Fix <http://www.cexx.org/lspfix.htm>, WinsockFix
<http://www.tacktech.com/display.cfm?ttid=257>, or WinsockXPFix
<http://www.spychecker.com/program/winsockxpfix.html> a shot.

If no help yet, reset TCP/IP on the client computer.
http://support.microsoft.com/?id=299357

Start - Run - "cmd". Type "netsh int ip reset c:\netsh.txt" into the command
window.

What changes if any have been made to either computer just before this problem
was observed?

If no changes were made to cause this, then you need to check for a hardware
problem. Either a bad network adapter on either computer, or a bad cross-over
cable.

Thanks for your reply.

What I mean by the network has quit functioning is that the client
computer can no longer use the host printer, the client computer
can't see an internet connection, and the client can't see shared files
on the host. This happened with no apparent changes to either machine.
One day it worked, the next, it didn't.

I assume I am using ICS, as I have not added any networking features to
the host computer. If the host is supposed to give the client an IP
address, then why does it ask me for an address? Sounds as if I need to
get a router and let both machines talk to the router through ethernet.

Chuck,

Thanks for the advice - I assume the e-mail address is adequately munged
now.

I did not attempt direct changes to the registry through regedit, but
did run

netsh winsock reset catalog

and

netsh int ip reset. No joy.

The host recognizes when the client is disconnected, but when it IS
connected, won't make the connection - it just says "acquiring network
address," so I can tell the host network card is probably functioning. I
AM running norton firewall, but have disabled the one in SP2, and
specifically listed file and printer sharing as exceptions and
specifically disabled the firewall for connections to the client
computer through the local area connection.

I also tried using the network wizard to reestablish the network, but it
ends with a message saying it failed, but that I might want to try
manual configuration.

In addition, I had this problem a few weeks ago when I acquired the
modem - and it disappeared after I reset the network. Now it has
returned, so I assume that the network card in the client is
functioning, but that I am back to wherever I was the first time I tried
to get the network up.

Thanks for the tip - I have now been to the site and I have more
questions. I was asked by another person if I am using ICS. From all
that I can read, if I used the network setup wizard to configure the
network, then I must be using ICS. HOWEVER, on one of these pages, I am
instructed to find the file C:\windows\inf\ics.inf. This file does
not exist on my computer, nor can I find any reference to the file on
the Windows XP setup disk.

Sooo, I have no idea whether I am using ICS and no idea how to find,
use, modify or adjust ICS if I have it. Ideas?

That's what I'd do, honestly - but see if the other replies help. If your
'client' computer isn't getting a DHCP address from the ICS box, it may not
get one from a router, either - google for LSPFix and see if it helps.

Aaargh.

I gave up and bought a router (Netgear wireless with 4 port switch).
Although both computers can individually connect to the net through the
DSL modem, neither one can talk to the router, so with the router in
place, I have no DSL at all. Well, at least I can connect the two
machines one at a time to the net and get mail, etc. However, the
router is a paperweight at present. A call to my ISP says the router
should work with the modem, but calls to Netgear result only in a busy
signal. Got LSPFix, but haven't tried it yet.

Forget about wireless for now and see if it works with Ethernet cables
plugged into the Netgear's switch. You should receive IP addresses
automatically. Run ipconfig /all to check. I usually set up the Netgear to
specify the DNS servers of my choice in the DHCP scope rather than using the
Netgear's LAN IP for DNS & forwarders in the NetGear - has worked a lot
better for me.

Once you have IP addresses on each computer (should be 192.168.0.x, I
think):

Ping the gateway IP address (the Netgear) - successful?
Ping a DNS server like 4.2.2.1 - successful?
Ping each computer's IP from the other...successful? Make sure you don't
have your firewalls enabled (or configure them so you allow file/print
sharing & ICMP on the LAN)

Well, at least I can connect the two
machines one at a time to the net and get mail, etc. However, the
router is a paperweight at present. A call to my ISP says the router
should work with the modem, but calls to Netgear result only in a busy
signal. Got LSPFix, but haven't tried it yet.

You'll really only need that if you can't get an IP address, I suspect. You
need to run it if you had winsock corruption, tho - which often is the
result of a bad malware infestation (the removal of the malware often
corrupts it). There's no harm in running it.

I had the same problem when I installed SP2.
I also has the same type of connection you had, i.e. DSL USB modem,
network cards and a crossover cable. ICS and file sharing always worke
good before I installed SP2 on the host PC (the one that connects t
intenet). At first I couldn't do anything with the LAN, than one day
as if by magic, I could share files and printers. But no interne
connection! I had to manually configure the lan card's addresses, an
now at least I can use ICS. but still, I can't open all the web page
nor use e-mail on the client. I left a post named "SP2&ICS" on thi
forum, see if you can find some suggestions.
