I have a desktop PC and Laptop side by side at work on the same network. Both are running Windows 7 and both have IE8 plus other browsers (Firefox, Opera & Safari). When browsing the internet I can get to certain pages but not others (for example - I can go to http://www.paypal.co.uk
but not the Paypal help page - https://www.paypal.com/uk/cgi-bin/helpweb?cmd=_help
This problem occurs with both computers.
However, when I disconnect the laptop from the network and use a totally separate wi-fi broadband router I can access any page I like with ease.
Both machines are less than 2 months old so everything is pretty much up to date.
Hope somebody can help........
