Question
Recovery policy configured for this system contains invalid recovery certificate
When I try to use EFS on any of our workstations (XP or Vista), I get the 'recovery policy configured for this system contains invalid recovery certificate' error. I believe I need to create a recovery certificate on the Domain controller (SBS 2003), can anybody walk me through this please?

Not specific to your question as the link above provides your answer, however EFS is okay for encryption but has its flaws. You will be able to find them with a bit of searching.
In our experience, BitLocker and BitLocker To Go on Win7 are far better solutions to the need to encrypt data. It is very difficult to circumvent or crack BitLocker based encryption.
Philip
Totally Agree with Philip as bitlocker is superb, I have been using it at home with some external drives and at work as well and it is much more sophisticated then EFS.
You can also use truecrypt if you want to encrypt the contents of your client pc's only ;
www.truecrypt.com (free - opensource)
Yes, you would need a valid certificate, generated by your internal CA
Can you check in Administrative tools if a certification authority is installed on your domain controller ?
the link i posted is related to windows 2003 and it tells you :
"If you choose Create Data Recovery Agent during this procedure, the domain
controller will contact a Windows Server 2003 family certification authority
(CA) to request a certificate based on the EFS Recovery Agent certificate
template. If this template is unavailable or does not allow you to obtain a
certificate, Windows displays the following message: "Windows cannot create a
data recovery agent."
You can't create one using that method without a CA"
Which is why I recomended to use truecrypt as it is not dependent on any such services.
