There are some malware infections that specifically block Microsoft.com.
Have you thoroughly checked your system? Have up to date antivirus? I
suggest also running
Malwarebytes
http://malwarebytes.org/ and
SUPERAntiSpyware
http://www.superantispyware.com/
Checking your host file as the other poster mentioned is worthwhile, and you
may or may not see an erroneous entry for Microsoft.com, but you need to
address the issue of how it got there and the likelihood of ongoing
problems.
