Hi
There are a number of sites explaining how to do this for standard XP (32bit version) it should not be significantly more difficult for 64 bit XP or Windows server 2003

or for 64 bit version
https://neosmart.net/blog/2007/windows-xp-x64-service-pack-2-released/
have you tried to do this your self and failed?
Have you tried installing XP 64 bit then adding 64 bit device drivers (motherboard, network , graphics etc) then installing SP2 ( or possibly SP1 then SP2)?
It would also be interesting to know why you need to continue using XP (32 or 64 bit versions) long after updates & bug fixes are no longer available
is your PC hardware old (2001 to 2009 when XP was on sale) or newer ?
If modern PC hardware does it support Windows XP 64 or Win 2003 server
If an old motherboard it maybe worn out (capacitors about to fail)
what country are you in if you wanted to post a XP CD ?
