I have a toshiba laptop with vista sp1. the other day i remove an expired trial version of norton 360 and
installed panda security. After restarting with panda installed, my browsers no longer find the internet.
Neither firefox or IE will find the internet, IE says 'cannot display the webpage' and ff says 'server not found'.
i've removed panda but they still don't work. i know my internet connection is good because Network and Sharing Center
shows im still connected and my other programs can still update.

anyone have any idea what happened, or how to fix it?

edit: this also had a mexican dialup isp program installed, as it had been taken to
mexico over the holidays. dont know if that will make any difference. but i have
removed it also.

Ok. That means, you have a connection, but DNS is messed up.

Go Start>Run (Start search in Vista), type in:
cmd
Click OK (in Vista, while holding CTRL, and SHIFT, press Enter).

In Command Prompt window, type in following commands, and hit Enter after each one:
ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew


(there is a "space" before each "/")

Restart computer.

OK....

Turn off computer. Disconnect router, and modem from power source for 30 seconds.
Power them back on.
Restart computer.

If that doesn't work, bypass router, and connect computer straight to the modem.

If that doesn't work...
Go Start>Run (Start search in Vista), type in:
cmd
Click OK (in Vista, while holding CTRL, and SHIFT, press Enter).

In Command Prompt window, type in following commands, and hit Enter after each one:
ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew


Restart computer.

If that doesn't work...
Go Start>Run (Start search in Vista), type in:
cmd
Click OK (in Vista, while holding CTRL, and SHIFT, press Enter).

At Command Prompt, type in:
netsh int ip reset reset.log
Hit Enter.
Type in:
netsh winsock reset catalog
Hit Enter.

Restart computer.


If that doesn't work...
Download, install, and run WinSockFix: http://www.softpedia.com/get/Tweak/Network...inSockFix.shtml (doesn't work in Vista)
Restart computer, and check again.

If that doesn't work...
Download Dial-A-Fix (DAF) (doesn't work in Vista):
http://wiki.lunarsoft.net/wiki/Dial-a-fix#...2C_and_articles

Have XP CD available in case DAF needs a file. Likely not!

Check all boxes on the screen (clear any restrictions if it shows any)
Then click GO!

When the entire page is finished click the HammerHead at bottom to go to the second DAF page.

Here, one at a time, do the below:

Reinstall BITS
Reinstall Windows Firewall
Repair Permissions
Reset networking

Watch for any File not found or other errors and make note as this may lead to the fix!

Restart computer.

Do you have any errors in Device Manager?
Are you checking your connection being hard-wired, or wirelessly?
Do you have Vista DVD?

1. Try to reinstall network adapter driver anyway. Uninstall current one first.
If no go...
2. Go Start>Run ("Start Search" in Vista), type in:
sfc /scannow
Click OK (hold CTRL, and SHIFT, hit Enter in Vista).
Have Windows CD/DVD handy (with Vista, most likely, you won't need it).
If no go...
3. Try Vista repair install: http://www.vistax64.com/tutorials/88236-re...tall-vista.html
