This machine connects to the network but cannot access the web at all. I am pretty sure that the issue stems from the recent uninstallation of Cisco VPN and subsequently McAfee. Even before terminating McAfee, the machine would not connect. I have tried all the uninstall tools available for McAfee and tried to manually force it out of Windows following the directions on McAfee's website. Everything I try gives me an error.
I've gone through startup on msconfig as well as services and terminated everything non-windows.
Windows firewall is off.
It is highly unlikely that it is virus related because it has rarely been used for ANYTHING but replicating my stupid Lotus Notes database.
I've tried booting in safe-mode with networking.
The reason I was chasing down mcafee was the epolicy orchestrator was in my opinion the only remaining conflicting software that could be holding my connection up.
One more thing...I can ping www.google.com or any other website from a cmd prompt but if you go to type that address into a browser, it doesn't work.
It is NOT hardware related. I have another hard drive formatted for this machine and it works fine (as fine as Windows can work).
It is not wireless. The problem persists whether wired or wirelessly connected.
Anyone care to help keep this machine off the trash-pile?

Brief, targeted next steps (after the Cisco VPN / McAfee uninstall that described). As suggested, DNS is worth checking — but when command-line name resolution and ICMP appear to work while browsers fail, the usual culprits are a system proxy, a leftover network filter/LSP installed by VPN or AV, or a corrupted Winsock/TCP stack.

Check and clear any system proxy first (Control Panel → Internet Options → Connections → LAN Settings — disable any proxy or automatic config script). Also inspect the WinHTTP proxy and clear it from an elevated command prompt:

netsh winhttp show proxy
netsh winhttp reset proxy

Reset the Windows socket/catalog and TCP/IP stack, then reboot (run the commands elevated):

netsh winsock reset
netsh int ip reset

Next, remove leftover virtual adapters and filter drivers. In Device Manager choose View → Show hidden devices and uninstall any Cisco VPN adapters, TAP adapters, or anything obviously McAfee-related. In the network adapter Properties unbind third-party filter clients if present (back up first). Use Autoruns (Sysinternals) or Services.msc to find and disable leftover McAfee/Cisco services or drivers that persist after uninstall. Always create a restore point before removing drivers or editing the registry.

If the problem persists, check Event Viewer (System/Application) for NDIS or driver errors when a browser attempts a connection; use an alternate browser or a bootable Linux USB to confirm the issue is OS-level. As a last step, a system restore to a pre-uninstall point or an in-place repair / reinstall of Windows will clear deeply embedded network hooks — since there is a known working drive available, consider cloning or migrating data to a clean image if time is short.

Check to see if you have a domain DNS server designated and if it is working. From command prompt try:
nslookup google.com
you should get a sresposnse saying something like this:
C:\Users\Rodney>nslookup google.com
Server:
Address:

Non-authoritative answer:
Name: google.com
Addresses:




the first part tells you what dns server you are asking for the ip address. if that does not work try this and I bet you get an answer:

nslookup google.com

That will query the primary nameserver on the web. If that works and the first one did not your problem is your do not have a valid DNS server set for the network card. Set it under the "Local Area Connection X" and the Properties for Internet Protocol (TCP/IP) at the bottom. If obtain IP automatically is set the set DNS to the same thing and OK out of the properties then reboot. If it is set differently send the data and I will try to give you an idea.
