I am getting the following error message with every second web site I
try to reach. If I tell FF to Retry it will generally connect on the @nd
or 3rd try. Any one have any suggestions as to what to look at to solve
this. I am running Windows XP Pro.

Server not found
Firefox can't find the server at lab.berkerpeksag.com.
* Check the address for typing errors such as
ww.example.com instead of
* If you are unable to load any pages, check your computer's network
* If your computer or network is protected by a firewall or
proxy, make sure
that Firefox is permitted to access the Web.

This error is now starting to happen with Thunder bird as well.
