Backup Exec Agent for Application and Database

Hi,

I got the following Servers:

Server 1: Windows 2000 - as a Domain Controller

Server 2: Windows 2003 - as a Domain Controller

Question: Correct me if I am wrong.

1. Does Agent for Application and Database support Windows 2000 Active Directory ?

I guess its not supported. Since, Windows 2000 OS is not supported by Backup Exec 2012

2. Does Agent for Application and Database support Windows 2003 Active Directory ?

3. What funtional level should my Domain and Forest be in order to be supported by Agent for Application and Database?

Thanks,

Paul
