Cannot access yahoo mail and some other sites

Hi,

See if you can ping www.yahoo.com from your command prompt.

GO TO:

START | ALL PROGRAMS | ACCESSORIES | COMMAND PROMPT

At the command prompt type: c:\ ping www.yahoo.com

If you can reach it then it will send back a reply. This tell you that your computer is able to reach www.yahoo.com. If your not able to reach it and it times out. Then you need to check where it fails.

You can use this command at the prompt too : c:\tracert www.yahoo.com

Which basicaly test the router path to www.yahoo.com. When run that command, the fist router path should be your Firewall/Router then the ISP. If you get up to your ISP at least then it's ok because some router paths are blocked.

So if you only reach your Firewall/Router as the first hop and it doesn't go any further then your firewall/router may be the problem. Check to see what sites were blocked. If you're still having trouble accessing it then connect to your ISP without your firewall/router, then try that. This should altimately work.

If you still cannot access www.yahoo.com then check your browswer settings under

TOOLS | INTERNET OPTIONS | Then click on security tab. Then click on restricted sites, then click on the button that says " Sites "
Under Sites: Make sure what www.yahoo.com or *.yahoo.com are not there. If it is then erase it and try to access yahoo.com. You can also try to look for this first before disconnecting from your firewall/router.

Hope this helps.

Victor.
