TCP/IP won't renew to router's addy

[Rachael]

Below is my original post.

I don't have ICS (assuming that's internet connection
sharing) set up, so that shouldn't be an issue.

I went home last night. Now, I can't even connect to the
internet direct without the router. I thought my ISP was
down, but when I called, they couldn't find any network
outages. My ISP tried everything to release and renew my
IP. I could ping their ip, and they could ping me, but I
coudn't get on the internet at all last night.

She figured I must have some kind of internal firewall or
something running that's screwing up things. I have
this "IPv6" thing in XP. Could that be it? And there's
ICF (Internet Connection Firewall) which I turned off.
What could that be doing to prevent proper IP renewal? Is
there anything else in XP that's built in that might be
causing it.

I have norton anit-virus, but I don't think that would
impact it.

I'm desperate here. My computer is out of warranty (just
barely), so I can't call them. Help!

Thanks for the quick reply. What is ICS? I was looking
for info on my computer last night, and I couldn't figure
out what it was. I thought maybe that was why. See my
replys below:

Not that I can think of. Check your DHCP server settings on the
router....are you 100% sure they're correct? And there is no other DHCP
server anywhere on your network? Note that if you have ICS enabled on a
computer, it will act as a DHCP server....disable ICS if it's enabled
anywhere (doesn't sound like you need it anyway).

I can't check the DHCP settings on the router as I can't
even log into its control system. My computer is the only
one on the network. Once I get mine working, I will be
tackling my boyfriend's MAC issues to add his to the
network.

As stated above, what is ICS and how do I disable it (I'm
new to XP)?

Clearly DHCP server (router or ICS) related as it's happening on other
computers with other operating systems & versions....

Once I figure out how to disable ICS, I will try again.

How are you seeing that? What did you type in the

command line?

when my computer is attached to the router, and I type
in "ipconfig", one of the lines has that webaddress. I
will post exactly what it says when I get home tonight.

Check the above suggestions first - but of course make sure all computers
run current-generation antivirus & update signatures regularly (daily if
possible).

Does your router include a built-in firewall? If not, I'd consider getting
another that does. NAT alone isn't enough. Or get firewall software on all
the computers.....but the former is my preference for networks (even if you
*also* choose software firewalls on the connected

computers).

I pretty sure this router has a built-in firewall, so I'm
ok there. (it was free from a friend when he went
wireless). I run spyware removal daily (several times)
and update anti-virus whenever I use my computer.

Thanks for the help. Let me know about ICS so I can start
there tonight.

It almost sounds like you have two DHCP servers on your network and that
could cause a problem, you want your router to be the only one.

Norton Anti-Virus might be causing problems, you might temporarily uninstall
it.

IPv6 is probably not the problem.
