website that i cant acess

hello guys,

Well, the thing is... from the network in the company where i work i access the company?s website normally. But from 2 of the computer in there i dont.

I had this problem last week, but worse, when all of the computer from de company couldnt reach the website... as we got 2 internet conections, i tried from both and even so i couldnt access the website. Then i transferred the website from a hoster in USA to a new one in London , and well, it worked the hole network in the company now access the website excepting one from the designe department and , the most important, the one from my boss?s table doesnt reach the website too.

What might be blocking the access for these pcs.

Just to let you know... i usually upgrade the news in the website and also manage the webmail that we got here. But, every time i try to do any thing from any one of these two pcs i dont make it.

Thanks in advance.
