Windows 2000 Server and Windows 2003 Server are the only fully supported
versions of Microsoft's server OSs as of Jan. 2004. Extended support for Windows NT
4.0 Server ends Dec. 31, 2004, and support other than security-related hotfixes requires a
custom support contract.
As with other products, server OSs are supported with only the most
recent service pack, but customers receive one year to migrate to that service pack. This
means, for example, that Windows 2000 Server with Service Pack 3 will be supported until
June 26, 2004.
