Does IPsec in Windows XP Sp3 support AES-256 encryption?

Update:

  1. Windows IPsec FAQ says that it's not supported in Windows XP, but maybe they changed it in Service Pack 3?

It is not supported prior to Vista.

I'm using Windows XP SP3. When I add a new IPsec filter rule, the only options for ESP I get are DES and 3DES, so the FAQ is correct - there is no support for AES prior to Windows Vista.
