I have recently taken a job as a Network Administrator. I am not sure what the last Admin has done, but when a user creates a folder or a file instead of making the owner Administrator it makes owner the user that has created it. I have done contract work for this business in the past and this is not how it was setup before. How can I correct this issue? I have tried changing permissions over and over again but still end up with the same thing. Any user can create a file or directory and remove everyone even Administrator and add the users they wish. To me this seems like a security risk and a big mess. Does anyone have any ideas on how I can correct the permissions?

Thanks,
