I have one xp home laptop that can not communicate with the internet via
dial-up, direct broadband, or over a network. Over my home network the
laptop can communicate to share files etc, just not internet. The other
computers all work fine for everything, including internet. It started out
as just an network problem as this laptop was not being assigned the proper
ip address via DHCP from the router. I fixed that with a manual ip on this
computer and all the other network functions worked fine.
I have reinstalled communication device drivers, uninstalled and reinstalled
tcip protocals etc. I then tried dial-up with a new set up aol disc that was
lying around the house and although dialing occured it could not communicate
properly and the install failed. I also tried direct internet through my dsl
modem and communications could not take place and a new verizon dsl install
failed also. My connection via wire or wireless Lan say good connections and
work for networking.

I have also tried a windsockfix utility. System restore was no help as when
I went to use it I was only given the option of the morning of the current
day, and this was too late.(Don't know why this happened as it is turned on
and I have used it before).

So it seems like communications software is corrupted as it is all devices.
Any ideas on what to do?
I could reinstall windows but this would be a major pain as I have much
software installed and would take a major effor to reproduce. Can only
communications be reinstalled?
This is a 3 yr old laptop with OEM windows XP so reinstall would have to
start with SP1 probably and take a lot to catch up.
Once again, any ideas would be a big help.
Thanks

Let me add that I turned off all firewalls-XP and shutdown my CA software,
and had made no changes in these.
 
You could try removing and reinstalling TCP/IP - make sure you install
another protocol before you reboot. After reinstalling TCP/IP remove the
place holder protocol:

But, before you do that open a command prompt and run ipconfig /all. Since
you have manually configured the IP addresss, you must also manually
configure the default gateway. This must be the LAN IP address of your
router. Also, you must have the LAN IP of your router or the IP of your
ISP's DNS server set for your DNS server. If these settings are not
correct, reconfigure them.

Doug, thanks for the response. I had been setting the dns and default
gateway previously. The default gateway did not stick on reboot as I recall,
and had to assign again manually sometimes.(perhaps this was just on
alternate setting, not 100% sure).
As far as the uninstall, I had not uninstalled TCIP from all connections
just one at a time previously. I will try this. However I am having
trouble uninstalling, as the uninstall option is grayed out when I click on
tcip. I have unchecked tcip and am rebooting to see if I can uninstall after
that.
By the way-this forum seems to have a quick timeout where what you write
gets wiped out after you hit post and I get a server unavailable page with no
back option.
