Logging in to Hotmail from MSN Webpage

On our desktop computer, when I click the hotmail link on the MSN webpage, it isn't able to load the hotmail sign-in page. (the default page "Internet Explorer cannot load this webpage" comes up instead)

Then I attempted the same thing from our laptop, and the hotmail sign-in page opened immediately.

To determine whether the problem is with the desktop computer, I copied the link/address that could not open the sign-in page for hotmail on the desktop:

https://login.live.com/login.srf?wa...x&lc=1033&id=64855&mkt=en-us&cbcxt=mai&snsc=1

Then I compared it to the link that did open hotmail on the laptop we are using.

The only difference was in a 10-digit number: 1351653518 in the link/address for hotmail on the desktop, contrasting with the 10-digit number:1351645171 in the link/address on the laptop that successfully opened the sign-in page for hotmail.

When I replaced the last 5 digits in the desktop link/address:53518, with the last 5 digits from the successful laptop link/address: 45171, and hit the enter key, immediately the sign-in page for hotmail presented.

Whenever I replace the five digits in the (unsuccesful) desktop with the five digits from the (successful) laptop, the sign-in page for hotmail comes up.

Does anyone know what I need to change (is it in IE settings on the desktop?) to correct this on the desktop? Direction will be appreciated greatly.
