Hi

If anyone can help with this problem that would be great because I'm on the verge of pulling my hair out.

A 2 computer network, 1 PC set-up as client which connects to another set-up as host, which is directly connected to the internet through a broadband connection.

The host computer has no problems and functions perfectly.

The client PC however, CAN connect to the network, so is capable of sharing files etc. CAN access P2P networks i.e. Limewire etc. and download applications but CANNOT access the internet, browse or surf the web

Both PCs run Mcafee security centre which includes the firewall, as this seems like a problem a firewall would cause. But I have tried disabling Mcafee on both PCs to no avail.

I have run this set-up for nearly 5 years at my old house but moved last week and now the exact same set-up is having difficulty.

I also cannot ping the internet from the client PC.

I have tried running windows network diagnostics but that say everything is functioning perfectly.
I have tried using static ip address on client pc, this did not work!

I have tried releasing and renewing ip address.

I know I am missing something, but can't think what it is, Can anybody help?

Two quick notes that tie the posts together and give a practical checklist for the same symptom (client on LAN can use P2P but cannot browse). This usually means one of three things: (a) a corrupted TCP/IP/Winsock stack on one of the machines, (b) incorrect gateway/DNS or a browser/proxy setting on the client, or (c) the host is not actually forwarding HTTP/DNS traffic (ICS/bridge/firewall issue). ended up repairing the host’s TCP/IP configuration and changing the host to act as a bridge; ’s suggestion to rerun the Windows networking wizard is a good first step but doesn’t always fix stack corruption.

Quick diagnostic checklist (run on the client first):

ipconfig /all
ping <host-LAN-IP>
ping 8.8.8.8
nslookup www.google.com
tracert 8.8.8.8
route print

Interpretation and repair pointers

  • If ping 8.8.8.8 works but nslookup or ping www.google.com fails: DNS is the problem. Try setting a public DNS (e.g., 8.8.8.8) temporarily to confirm.
  • If ping 8.8.8.8 fails: check that the client’s default gateway is the host’s LAN IP and that the host is actually forwarding (ICS or bridge).
  • Rebuild sockets/stack when things look correct but browsing still fails (reset the Winsock catalog and restart). Some security suites (McAfee, etc.) leave kernel drivers active even when “disabled”; a full uninstall or vendor removal tool may be required to clear packet-filtering drivers.

Bridge vs ICS — brief clarity

  • Bridging joins the two network segments at Layer 2 and relies on upstream DHCP; ICS performs NAT and presents the host as the gateway. Picking the correct mode for the network layout is crucial and explains why switching to a bridge fixed ’s setup.

run the windows networking wizard on the client and make sure that you select "connects thru a residential gateway or another pc"

Thanks for the quick response. But no luck.

The windows netowrking wizard is how I initally set-up the network in the first place, I have tried doing this again just incase, but this did not work. Still have the same problem.

Any other ideas?

I've solved the problem. Thank goodness

In command prompt I typed:

Netsh int ip reset test.log

I also bridged the network connections on the host computer.

I now have a fully functioning network.

Thanks for the help though! Until next time!
