I am able to surf the web using Internet explorer, however, if I try to connect to Windows Live Message, update my AVGvirus databaseor download certain software it states there is no internet connection. This is when the firewall is off. When I run the diagnostic is says the internet is working fine. Can you help, thanks.

Hi, As you can using IE to surf the web, the network connection should be fine. According to your description, The issue is occurs on software side, not Windows Vista side. I suggest you take a clean boot to troubleshoot this issue. Clean Boot ============================= 1. Click Start, type "MSCONFIG" (without the quotations) in the Search Bar and Press "Enter" to start the System Configuration Utility. 2. Click the "Services" tab, check the "Hide All Microsoft Services" box and click "Disable All" (if it is not gray). 3. Click the "Startup" tab, click "Disable All" and click "OK". 4. Restart the computer and test the issue. Note: Clean Boot is a troubleshooting step. If some programs have been disabled, we can re-enable them later. If you see the System Configuration Utility, check the box of "Don't show this message" and then click "OK". Please monitor the system in the Clean Boot environment. If the problem does not occur, it indicates that the problem is related to one application or service we have disabled. You may use the MSCONFIG tool again to re-enable the disabled item one by one to find out the culprit. Hope it helps.
