Active Directory Security Issue w/Users and Computers

[somejoe]

Has anyone tried this?

1. Install "Adminstrative tools" on a workstation, i think it's adminpak.msi.

2. Logon to that workstation with average "user rights."

3. Open "users and computers" for your company's domain.

My experience has been, by doing the above, I can view ALL, users, computers, distribution groups, OU's, I can EVEN DELETE any users/computers left in the default folder with only having "user access"!!! WTF~!

Could I get someone to confirm that they can do this on their domain as well?

Any suggestions on how to secure this?

Thanks,
SomeJoe
