If you can’t access certain web sites, see if they are listed in the HOSTS file (with no extension). Apparently, web site addresses listed in there are banned and/or considered as advertisement sites. In Windopws XP Pro, that file is located under “C:\WINNT\system32\drivers\etc” directory which should be opened with Notepad. It’s a “read-only” file, so you should change that first.
I can now access classmates.com.
