Hi, welcome to the forums

What browser do you use?

If you use Internet Explorer then try the following...

1, Open Control Panel -> Network and Internet -> Internet Options
2, Click the Connections tab then click Lan Settings
3, If 'Use a proxy server for your LAN' is selected then de-select it, click OK then OK

Now try opening your browser and see if that's solved the issue.

If what Orbital Shark said here doesn't solve your issue follow the next steps:

1) go to start, type "cmd" in the search bar (without quotes), right click it and "run as administrator".
2) type this: "ipconfig /release" (w/o quotes) and press enter.
3) now type: "ipconfig /flushdns" (w/o quotes) and press enter.
4) now: "ipconfig /renew" and press enter.

If that doesn't solve it, do the following

1) type on the CMD window: "netsh winsock reset catalog" and press enter.
2) after done, type: "netsh int ip reset reset.log" and press enter.

Reboot and check if everything works!

And of course, report back... please

You're welcome, keep us posted.

In the meantime you may wish to install Microsoft Security Essentials. It works flawlessly with any Windows based machine

Bless You, Punkster! netsh cmds Fixed Network After McAfee Removal

As with stevejbf, I lost all network connectivity after I removed McAfee products. I already run MS Security Essentials with no trouble, but my company periodically auto-installs McAfee products -- and they create BSOD's within minutes (yes -- even with Security Essentials and all other security software removed).

My network loss occurred when I removed McAfee products from within an XP SP3 virtual machine running on a Windows 7 Enterprise host laptop (lots of variables created lots of fear that I'd never get this working, again!).

I had known enough to run the ipconfig commands. I also tried the diagnostics and "repair" buttons and links available in IE and Windows networking dialogs, to no avail.
When I finally tried the following final steps as advised by Punkster, my XP VM's network connections came back to life!:
1) type on the CMD window: "netsh winsock reset catalog" and press enter.
2) after done, type: "netsh int ip reset reset.log" and press enter.

3) Reboot and check if everything works!

What a relief! Now I have my weekend back!

Thanks again, Punkster!
