Looking for the softwares to monitor our file server

["Truong duc Luong" <luongductruong () gmail com>]

Hi all,
I'm a network manager at smal-size company. We've one file server
using Windows 2003 server. I'm only using Event Viewer to log all
operation with the file server. Recently, some important data in the
file server have been deleted.  So, I can't detect when does this
operation occurs? And Who do this?
To improve the logging capability, i googled and found this software:
Alfa File Monitor (http://www.alfasp.com/products.html). It meets with
our requirement, but very expensive (1.999 EUR).
Do you know any software like Alfa File Monitor (with less price) ?
The software can answer quetions:
- Who does delete, modify the file server?
- When does this occurs?

Many thanks,
