...using System Restore? To use System Restore which should take you back with things were good, click on Start-All Programs-Accessories-System Tools-System Restore.. At the SR window, select "Restore my computer to an earlier time". At the next "Calendar" screen, click on the bold date that was previous to your installation of IE7, then click on "Next" and follow the prompts to restart the computer and go back to when things worked correctly..
Hope this helps.
I installed/upgraded internet explorer 7.0 on my home pc. After re-starting my computer I could not connect. After looking up my error message "unable to clear DNS cache" microsoft support suggested running the steps below:
If the service is not set to Started or if the startup type for the DNS Client service is not set to Automatic, follow these steps:
Right-click DNS Client, and then click Properties.
In the DNS Client Properties dialog box, click the General tab, and then click Automatic in the Startup type list.
Click Start, click Apply, and then click OK.
I did this and it did not seem to work, so I changed one other option in the DNS client- something about run this when the network manager logs in and I changed it to something local. Now I can not do anything when my computer starts up. I can not even get the dns client back up to change that option back.
There may be an issue with an alert that pops up due to a expired antivirus program which immediately attempts to open an internet window.
I have limited knowlege and even less time to fix this problem. Any suggestions?
