Win XP Vol. Key

Awhile back i bought $16000 Corporate copy of win xp 4 my company, it required no activation crap so you could use it on as many pcs as u want at once... I needed to use it for my home pc one day but my 4 yr old fed the disc to the goats. I still have the key. Can i get the disc somehow? the key is FY6Y3-?????-?????-?????-4HM8D
