can't renew IP?!

Questions for you experts out there. I'm not knowledgable with TCP/IP setup
so please bear with me... I'm running Windows XP on one PC and my cable
modem recently crapped out on me.

It all started with some unwanted plugins, perfectnav courtesy of kazaa,
wupdater.exe (no clue how I got that one) and a few others. I've already
removed most of these unwelcome guests using Ad-alert and some helpful info
I found on various forums, but now I've got bigger problems....cable modem's
interface is screwed up and I have no internet access.

I tried some troubleshooting suggestions, and I always come back to the same
point. I try to 'Repair' the modem but then I get an error message stating
that the 'renew IP' operation failed.

I tried using the ipconfig /renew command, and I get a message along the
lines of "Can't perform this operation on something that is not a socket".

I tried removing the modem and re-installing the driver, but to no avail...

I'm fairly certain the problem is not with the modem, as far as I can tell
it does connect to my ISP and as per the traffic stats it's sending packets
but not receiving any. I suspect I screwed up some network settings when I
was removing all the spam-ware...

Any suggestions/opinions? Please help!!!! or suggest other resources....

TIA

The problem could be on your ISP end. I had a similar problem. Basically
the IP address gets bound to your MAC address. When the MAC address
changes, it screws up the settings.

Now this sounds weird, but it did work for me. Unplug the modem for about
an hour to allow things to reset on the ISP side of things. Then plug
everything back in. (Don forget to shut down the computer).

Hope it works.

From a cmd prompt...
netsh int in reset >> resetlog.txt
Will reset your TCP/IP stack.

It also sounds like you may have a LSP hijack.
Check HKLM\local
machine\services\currentcontrolset\paramters\namespacecatalog \catalog
entries\
there should be 3 entries. If four or more, use LSPfix to get rid of the
extra.

Don't know about LSP hijack, but I think your first suggestion would've done
the trick.

I say 'would' because I actually found a neat little application,
winsockxpfix.exe, which essentially does the same thing, removes winsock
entries from the registry and re-installs a fresh batch, then resets the
TCP/IP stack as you suggested.

Anyway...I'm back in business, thanks for the hints!

I had a customers XP box that looked to have a failed network card and
it would not renew the IP either. I found that it was a stack problem,
but I didn't want to wipe the machine....

I tried the net fix command as shown on the MS site, but it didn't work.
I had to export the WINSOCK and WINSOCK2 registry trees from a working
machine and import them to the broken machine - worked fine after that.

The was the first instance I've seen of this. It appears to have been
caused by a search bar type assistant program loaded by the owner of the
machine.

Search bar assistant....hmmm, sounds like Perfectnav, at least I believe
that was the culprit in my case.

Strange thing is, as far as I can tell this perfectnav browser assistant was
on my machine for quite a long time without causing the problem I described
here. I tried to dig up more info on this and it turns out it's been causing
a lot of other problems like slowing down internet explorer, eating up CPU
time to name a couple.

Oh well, lesson learned...
