File Encryption -

I am looking for solution that will encrypt files in Windows XP Workstation  and Windows 2003 Server environment?

There are two things that I am trying to acheive:
1.) If a laptop is lost the encrypted files could not be decoded. IE. If admin change password or the hard drive was read.
2.) Server admin could not add themselves easily to decrypt files.
3.) Recovery capablilites if OS crapped out and I need to access data legit.

I want to implement this solution for a  workgroup about 20 people.

It seem like Guardian edge would do the trick but I want to hear from the experts what tool they use. If I get good leads I will split points.

thanks

First thing in my mind is syskey and EFS, that would do the trick.

Another possibility is to use some Full Disk encryption software or even some standard Encryption Software.

My choice here is Truecrypt, since it's freeware, admins are just helpless since it's not using any underlying OS authentication methods.

TrueCrypt... syskey EFS is still possibly ineffective without the other "best practices" suggested by M$ for EFS... you shouldn't need those extra hoops. TrueCrypt, no hoops, no hope of recovery if you don't have the password. I didn't suggest it here first, and it fit's your criteria and then some.

bengoa,

They are all good.  It all depends on how you treat the KEY.  The KEY is every thing.  You need a copy of the KEY as a Admin in case the user loses the KEY or like you said something went wrong with the OS.  Never keep the KEY with the machine.  If a person got hold of the HDD and the KEY is in it, they can try to figure out how to get the KEY and decrypt everything.  Have the user use a KEY off of a Key drive or something.  Train the user.

If user loses the KEY, you can retrieve the files with your copy of the KEY.  Make sure that you change the KEY afterwards.

The best is choose an encryption type that fits your budget: RSA, PGP, TrueCrypt, etc.  Keep in mind how valuable your information is.  Sometimes, it is too valuable to put a small price tag like TrueCrypt.  Since it is free, there is a higher chance a decrypter is created.  The higher the cost the less chance some one would buy to try to decrypt.

So, ask What is my budget?

I do not agree with most of the analysis of InfoStranger.
I deny it's more likely TrueCrypt gets "cracked" than any other commercial software, besides they're probably using the same cipher.
I won't go in depth on why it's better to have a completely opensource software doing the encryption for you, but every security expert will agree on that.
What it's true is that a commercial software might (and actually will) offer you more "integration" with your infrastructure, possibly giving you enterprise consoles to control its use, policies management and such.
What it's UNtrue is that a commercial software is more secure than a well written open source (and free) software. Quite the opposite, in my not so humble opinion.

PGP/GPG are standars for encryption, no just file system... e-mail, everything. they use public/private key algorithm so you need to keep safe your private keys and the phrase to use it.

Yes, commercial or  free it doesn't make a difference when it comes to crackers... they don't need to buy a legit copy there are plenty of cracks and warez sites to download any popular software for free. What PGP/GPG and TrueCrypt... and to some degree EFS, have going for them is that they all use Public-Key crypto. With EFS, you do indeed have to secure the key by copying it off the system and using syskey to help you do that. With PGP and TrueCrypt the keys are on the system, however there are keys to the key if you will. They can be passwords, and or keyfiles: http://www.truecrypt.org/docs/keyfiles.php
There are other benefits also: http://www.truecrypt.org/docs/plausible-deniability.php
PGP is also like this, and still bruteforce is likely to be as fast as anything else... a keylogger is ineffective if a keyfile is used.

You can disassemble "private" code as well as you can public code, that's why any popular program has a crack, keygen or patch... you can simply rewrite the code and reassemble, and it no longer does that check. There are no viri for Mac's, Linux, BSD etc... not because the code is proprietary or closed, it's because the code is well written and reviewed. When something is found, it's patched much quicker than M$, but they (M$)are getting better. TrueCrypt and many others will fit the criteria for this user quite well I think.

Thanks for the input and discussion. I was think I was going to get a lot of M$ solution but the experts have opened (SOURCED) my eyes.

RichRumble I appreciate your comment a depth.

I have started another question that look at the commercial Encrytpion Program:
