Here you are! Just want to mention that I'm currently managed to publish 
my (continuation of your) TLS fix I did half a year before. It will 
finally solve this XP/Sever 2003 problem. It is available here but isn't 
finished now (fill be in few days):

I hope you aren't against it is based on your work?
