I am looking at two machines both similar in age and both similar in construction and both have lost the ability to surf the web. They will log on but then they will not go to any particular websites. I continually get the IE failed to open search page dialog, or DNS server error dialog. One is using Earthlink and One is using AOL. I have checked both for spyware and removed what it found I have also scanned both with stinger and neither of them have viruses that stinger identified. I really need to get these two machines working. Any ideas?
