Auditing file and directory deletion on WS2003

Real dumb question

I'm trying to figure out who is deleting a directory on a WS2003 box. This box and all clients are on a domain.

I've enabled the auditing of AD objects, and have also gone to the directory and in the sharing / security section set up auditing to log any successful or failed attempts at deleting the directory.

Question is, to which user(s)/group(s) do I put this :confused:

If I do "everyone" or authenticated users? The thing is because I have no idea who is doing it, I don't know which group to specify. Ideally, I want anyone and everyone to be logged.

I don't have access to the domain controller nor have access to any account with domain administrative privileges. I do have a local admin account I can use and can log onto the WS2003 box with that account to set it up. But in my attempts so far with testing, nothing appears to get logged :confused: Maybe there's an inherited policy from higher up that I can't see. :confused:

What's the best practice for this? Scoured google and the like, but can't find any good quality explanations (that don't require credit card numbers to pay for ebooks). :(

edit: as well as the AD account, can I find out which PC the delete command was issued? (we have some accounts domain accounts that are used everywhere so just a name won't help find out where it's happening)

TIA
