I had to fix a customer's server and he gave me the 2003 server disc to fix it with.
Hopefully what you mean is they gave you the Server2003 CD to work with on fixing their server, and you gave it back when done. We'll not support piracy.
i notice it seem to be Xp without all the extra goofy features.
That would probably be because Server
2003 is for running SERVERS...not end-user desktops.
Windows Server 2003 is just what it is...a Windows Server. The difference between XP and 2003 is that one is designed for end-users, the other is for servers.
Microsoft has a wonderful section of their website dedicated to Server 2003. If you want to know all the ins-and-outs of 2003, that would be the best place to look.
The benefits are that 2003 will let you run as a full-blown server, and that the "tracking" features are turned off by default (instead of as in XP where you have to turn them off manually).
