Ie Cannot Display The Webpage

when i try to open my email or face book i get the above message.yet,i can open other web pages on the internet.my pc shows i have a good connection.i can go to another pc & open email & facebook with no problem.i did a system restore on the problem pc but no change.can someone give some advice?

 

Just some information on both computers.

What operating systems are on the two computers you talk about? XP, Vista, 7?

How do you connect to the internet with both computers? Wireless or Wired?

Do you use IE on the other computer or another browser?

Also what security software do you use, more specifically what firewall?

Also on the computer where you can't get to your email or facebook, have you tried getting to the sites on another browser like Chrome, Firefox or Opera? If so did it work?

 

vista,wireless,IE,avast,both pc's.not sure about firewalls.did not try another browser.someone said it sounds like the security certificate might have expired.this morning the wife was able to access both email & facebook for about two hours.then the pc resorted back to the same problem.

 

As a starter try clearing your cache, all of it including browsing history, then try accessing Facebook or your email and see if it works.

 

Make sure, your settings are correct.

2. Double click Network Connections (Vista/7 users: Network and Sharing Center)
3. Vista/7 users - From the list of tasks on the left, click Manage network connections.
4. For a wired network connection, right-click Local Area Connection, and then select Properties.
For a wireless network connection, right-click Wireless Network Connection, and then select Properties.
5. From the General tab (Vista/7 users: Networking tab), click Internet Protocol version 4 (TCP/IPv4), make sure it is checked, and then click Properties
6. Make sure Obtain an IP Address Automatically and Obtain DNS server address Automatically are checked.
7. Click on "Advanced" button and make sure "IP Settings" tab looks like this:

8. Still in Control Panel double click on "Internet options" then "Connections" tab then "LAN Settings" button. Make sure "Automatically detect settings" is checked.

If that doesn't work...
Turn off computer. Disconnect router, and modem from power source for 1 minute. At the same time disconnect ethernet cable as well.
Reconnect everything.

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 and 7, 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
net stop "dns client"
net start "dns client"


Restart computer.

If that doesn't work...
Go Start>Run (Start search in Vista and 7), type in:
cmd
Click OK (in Vista and 7, 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.
