Computers that contain Windows 2000 and Windows Server 2003

You can set up a server so that it contains both Windows 2000 and Windows Server 2003. If you plan to do this, note the following:

  • Install each operating system on a different partition or, for dynamic disks, on a different disk, and install the applications used with an operating system on the same disk or partition with it. If an application is used with two different operating systems, install it in two places.

  • Windows Server 2003 must be installed last. Otherwise, important files that are needed for starting Windows Server 2003 will be overwritten.

  • If the computer participates in a domain, use a different computer name for each installation. Because a unique security identifier (SID) is used for each installation on a domain, the computer name for each installation must be unique, even for multiple installations on the same computer.

  • If you use the Encrypting File System (EFS) on a computer containing Windows 2000 and a product in the Windows Server 2003 family, the encrypted files will not be readable between the different installations unless you take one of the following approaches:

    • One approach is to ensure that all the installations are in the same domain and that the user of these installations has a roaming profile.

    • Another approach is to export the user's file encryption certificate and associated private key from one installation and import it into the other installations.
