"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I would try to do that using DSQUERY tool in LDAP query mode. Export results to a text file and then import it to Excel. Sort results by whenCreated column and you should see the oldest one (if it was not removed from the network :) )

dsquery * -filter "(&(objectClass=computer)(objectCategory=computer)(userAccountControl:1.2.840.113556.1.4.803:=8192))" -attr name whenCreated >>c:\DCs.txt

I hope it would help you
