Go to Window Directory > Windows > system32 > drivers > etc . After that you'll find a hosts file without an extension. Open it in a next editor like notepad. Go to the last line and put the following lines -
code:
65.54.239.80 messenger.hotmail.com
65.54.239.80 dp.msnmessenger.akadns.net
Restart Messenger and you're done
.
Moreover in about a day remove these so that your messenger won't cause problems when the server is up
.
