those sites you mentioned?
"The page cannot be displayed"
"Cannot find server or DNS error"
If you see any of the above error message, try the solution of Microsoft at http://support.microsoft.com/kb/246725/en-us
Also, have you try to use another browser to "test" if the new browser e.g. Firefox, Opera can access those sites?
Help! My 3 PCs are suddenly being blocked from several websites I frequent, and I have no idea why.
We run Spybot weekly and have McAfee VirusScan.
My 2 desktops are networked for Internet access and printing, and my laptop has Internet access via WiFi.
None of the 3 of these can access these sites (which include forbes.com, expedia.com, dictionary.com)
System info: The "main" PC which controls the Internet access is a Dell Dimension 4550 running WindowsXP. Internet access is a cable modem running through a Linksys Router.
Any help would be greatly appreciated. Please be gentle -- I'm not very tech-savvy!
