Minus one day to the end of
mainstream support for Windows 2000 and (surprise!)
Microsoft has released an update package with lots of
security fixes that replaces the Service Pack 5.
This update is available via Windows Update and it's rated as "high
priority". It requires SP4 to be installed. If you're one of the (many) people
that have servers that runs with Windows 2000, please update your server
soon.
