I seriously doubt you could do all that with Windows. Are all of these machines XP on a 2003 Server AD domain? You can lock down a lot of stuff, but there's still workarounds.

What kind of files are we talking about? Microsoft Office? The new Office 2007 server gives you the level of control that you want, but the users would only be able to work with the files when they're in the office and they'd have to use Office 2007. You'd also need the above mentioned setup where all the machines were strictly locked down.

Also, you want to make sure that all the machines are using hard drive encryption (so they can't just walk out with a machine and use it at home) such as EFS (built into Windows). Even under this setup, a very sophisticated thief could do a bit-by-bit copy of their hard drive while at the office (using something like Knoppix) then grab the encryption hash being sent back and forth over the network and then use it to decrypt the hard drive when they get home.

In short: To do what you want in Windows you,

It is also possible to do all of this in Linux, but you'd run into all the same problems with the exception of the weak encryption and the cost (only pay for labor).

In Linux, there's many ways to accomplish what you want, but here's how I'd do it...

That's pretty much it. Under that config the users will essentially be limited to what applications you provide to them and they won't be able to copy things to disk, to the Internet, or to share files across the network (so they could bring in a PC and copy the files to that). They also won't be able to copy the hard drive (it would be futile without the encryption key) or take the machine home and access it there (since they can't login *or* get the encryption key over the network).

I sure wouldn't want to work at a place that does this though!

Wow that seems like a lot of stuff, i seriusly dont think someone in my office is going to take my CPU that prety extreme, i was more thinking in a simple password based program wich prevented files (word xp,exel xp,ppt xp,pdf,autocad, etc) from being extracted from my pcs... well 100K is a bit out of my budget so i hope i find a simple/cheap solution, thanks for your help anyway and for informing me about the subject.

After reading my post again I realized I should have been more specific about Microsoft's Office Server... What you'd need is Microsoft Office Sharepoint Server 2007 + Microsoft Office 2007 (for all your employees) + Microsoft Active Directory along with all of their prerequisites.

If you add it all up, it gets very expensive.
