Technet Download problems

I’m trying to download SIMPLIFIED GRID COMPUTING THROUGH SPREADSHEETS AND NETSOLVE from http://ct.com.com/click?q=e4-ABpFQVkZ4oIYv82ZQ8nIPTwc91Ir , but the site says I don’t have the right password. I don’t know what it is, since the page doesn’t accept my normal password, and “updating” the password does no good. How can I download the above paper?
