That's because MSIE uses an operating system component for SSL/TLS, and the version of that component on Windows 2000 has only insecure or weak ciphers, and none of them is accepted by Wikipedia's servers. According to qualys (https://www.ssllabs.com/ssltest/viewClient.html?name=IE&version=6&platform=XP&key=18 https://www.ssllabs.com/ssltest/viewClient.html?name=IE&vers...), even on Windows XP it knows only insecure ciphers (small key size or the broken RC4 cipher) and weak ciphers (3DES has a small block size, which is now considered insecure).
