Just a reminder, Windows 2000 will reach it’s end of life in July. Microsoft has outlined July 13, 2010 as the date Windows 2000 will no longer be supported by Microsoft. There are already a variety of security threats in the wild where Microsoft has said they will not be releasing updates to protect Windows 2000 because they say it is not feasible. After next July, no support or new updates (except for online self-help) will be available.
In a related bit of news, Microsoft is addressing an issue latest Forefront antimalware client update won’t install on Windows 2000 when the installation is run via Automatic Updates. When this issue occurs, the update uninstalls the previous version of the antimalware client, and then tries to install the new version and fails, leaving the system without the antimalware service. Microsoft’s published workarounds are to decline the updates for Windows 2000 systems (976669 is the FCS slipstream client) and make sure that the previous FCS antimalware updates are approved (971026 and original FCS client), or run the install interactively as a logged on user.
My workaround… stop using a 11 year old operating system and upgrade to at least Windows 2003.
