Looks like XP x64. The AMD64 version of Windows XP was based on Server 2003.

This is 32 build not 64 bit build but i think his is build used for making port od Windows XP for 64 bit CPUs (amd64)

This build is from March 2015 (judging by the build tag), so that wouldn't make sense.

I'm guessing someone applied a Professional SKU to Server 2003, somehow.
