Since you are doing a one off by installing XP onto the server, I would advise rolling everything you can into that master ISO using nlite.  This provides you an installation path with everything contained within the one disk, but also in the event of system issues, you can also use the same disk for recovery purposes as well.
Hi, Just purchased a R210 as a bare unit and want to install XP Pro Sp2 - have the same problem as others - tried following info in thread and downloaded the two files.
