Windows Server 2003 on VirtualBox

Virtualbox works well with XP as a host and then server 2003 as the guest.
There are just a few setting that need tweaked.
In order to make the connection correct, you must set up the server to use a bridged network adapter instead of using NAT.  If you use NAT, you can't properly find the server using it's IP address.
As always, it is recommended that you set up a static IP to use on a server.
As far as I can tell, everything is supported just fine in vitualbox.  I currently have a Active directory domain running from it, as well as DNS, DHCP, WDS, and file and print server.
If you want to use external USB devices, you must install the guest additions and the extension pack.
After attaching, everything goes just fine in using the devices.  I use an external hard drive and USB printer on this server.
Finally, you must set up auto-login and put a shortcut to the server in order for it to start at boot, or if you want to start it manually, you can use remote desktop and do it remotely.
