What messages,if any, do you get when the connection fails?

Take the domain name out of the URL (for example, for Pistonheads that would be www.pistonheads.com) and try to ping it from a DOS command prompt. For example:

C:\>ping www.pistonheads.com

then you have a DNS problem.

When I tried this it said windows could not find C:\>ping www.pistonheads.com check the spelling and try again....does this mean I have a problem?

Cheers for replies folks. When I tried the above, I got a 'request timed out' message. Does that mean a DNS error. I have no problems with the vast majority of websites...

Try changing your DNS servers to the OpenDNS ones, if it doesn't help now, it will speed up your browsing.

That means the DNS lookup succeeded but the address isn't responding to pings. That might be because the destination simply isn't responding to pings (not all sites do). Suggest you try the same test from work and confirm that you get the same IP address in both places (proves that the DNS lookup at home gave you the right answer). If it says "request timed out" at work too then that means you can pretty well rule out DNS as the cause and need to start looking for routing problems.

Are you by any chance using a Belkin router? I had the exact same problem as you whilst using one. Ill try to remember how I fixed it

[JakeR]

BT home hub...

[sadako]

Turn the router off and on again, wait till the light stops flashing, put these into a dos prompt

ipconfig /flushdns
ipconfig /release
ipconfig /renew

[JakeR]

thanks Sadako, I tried that, but I got 'The requested operation requires elevation'...

Is there something to do differently on Vista?

thanks again
