Don’t use time.windows.com

At a seminar I once learned that we shouldn’t use the default ntpserver time.windows.com. Which is preconfigured in all Windows installations. This server is apparently under quite a big load. I can imagine, seeing how usually people don’t look twice on this settings.
To change it, change time and date settings, choose Internet Time and change to a less travelled ntpserver. In sweden we can use one of the following:

            server 0.se.pool.ntp.org
    server 1.se.pool.ntp.org
    server 2.se.pool.ntp.org
    server 3.se.pool.ntp.org

The Internet Time tab won’t be visible if the computer is member of a domain. then this settings is being handled by the domain controller.
