Error 404 on windows xp?

404 error page not found means that the computer is connected to the Internet, but that it cannot find the page linked to the domain name (that www.something.com, aka URL), or linked to the IP address typed into the browser (eg. Internet Explorer) address bar.

The error is usually displayed because of either one of the following reasons:

1) The web page does not exist or the website does not work. In this case the web page requested will return error 404 from any computer. Test using at list two different computers and two different network connections.

1. This usually translates in one of the following:
2. You wrote the URL in the wrong way.
3. The web page requested does not exist.
4. The web server hosting the website is down.
5. The domain name is not linked to the website anymore (setting problems or subscription expired)

2) Your computer's DNS or network settings are wrong.In this case the web page requested will return error 404 from this computer. The same page will be displayed using a different computer or network. One example of this situation is when some malaware disables access to Websites like Microsoft by changing DNS service. If this is the case the same page will be displayed using other computers, but you will get error 404 with this particular computer.

If this is the case, ensure that you have installed an efficient and updated antivirus. Run a virus scan.
If that is not enough to fix the problem, try the following reset:

1- Click Start >> Run >> regsvr32 /i browseui.dll>> enter

A dialog box with a confirmation message will be displayed. Click OK.

2- Click Start >> Run >> regsvr32 /i shell32.dll

Wait for the dialog box, then click OK.
