Default Administrative Share Permissions

[netsj]

I'm looking for information that defines what security groups are given access to administrative shares by default. I've found this article on Technet:

http://technet2.microsoft.com/windo...e891-4107-aa2e-9d180428055d1033.mspx?mfr=true

but that simply tells me that there are default groups, not what those groups actually are. Has anyone found an official 'list' or statement from MS about what these groups are on a 2003 server with current patch revision?

Thanks in advance.
