This is a strange one! My son's computer cannot open certain web pages. It started out shortly after he loaded SP2 but not right away. First thing that is strange is the passport sign in button on the MSN.com web page does not appear. It shows a red X and some text identifying the link but the button is missing. When you click on it it tries to open the web page but stalls and times out with the Cannot Find Server error page. I then did a full reload of XP pro SP2 and thought that would get rid of it but it didn't. Same missing button. Loaded Firefox. Same thing but instead of the error page it gives a error box saying data is empty. We all connect to the internet through a gateway computer which shares a dialup modem. The gateway has PC-cillen for the virus scan and firewall. I could easily access these web sites from my computer but now it is starting to stall as well and today I could not connect to any Microsoft web pages like their support pages or the passport sign it. We both can open most web pages like yahoo, earthlink, etc. but others we cannot. Is there some setting in the firewall that maybe was updated lately? Is there a virus locking us out of Microsoft so we won't be able to get updates? Please help!!!!! I'm so confused!!!!!
