If you care about compatibility with applications that use Schannel for TLS on Windows XP or Windows Server 2003, be aware of which ciphers it supports/doesn't support:
Note that there are no ciphers that use AES for encryption in that list.
tl;dr: Make sure TLS_RSA_WITH_RC4_128_SHA ("RC4-SHA" in OpenSSL) is in your server's cipher list if you care about Windows XP and removed the 3DES ciphers because they're "too slow."
