Why won't my internet explorer allow me to open certain web-sites??

I've just bought a new lap-top and now have wireless broadband however with all this equipment my explorer won't allow me access to some web-sites (national-lottery.co.uk, myspace, teletextholidays.co.uk)

Does anyone know what's going on?? Why is my lap-top trying to wind me up??

Do i need to download anything?? I've increased my content advisor to the max but still no joy?!?!

Please help

Which browser are you using? What do you see when you type in the website name on the addressbar of the browser? Is you are using IE try meddling with the options in Tools-Internet Options and change settings to allow all websites. Some countries also have restrictions against certain websites like the UAE for example.
What is the eror message when you are blocked?

Is it permissionor access or password or is it connections?

If so there maybe something about your security settings that need changing such as content or javascript

Go to Tools -Internet options- and then settings and take a look at what is ticked or not and change the seetings.
I have IE7 and Firefox and it only works 50% of the time Firefox does so it's probably that Explorer cant find the command to run the internet which is common with wireless internet (especially Hughes Net, it always says "This Page Cannot Be Displayed" when i'm on).
Check the Internet Option of your laptop it should be medium or you might installed antivirus or firewall, those might block internet acess.
