No it must be legal. Wished problem came sooner as last year we had Windows 2003 server at work, but it has been replaced with SBS now. I know about how it works with ISO's and already did that for Windows98SE in the past. Just don't want to purchase Windows 2003 to find a little bug somewhere. If it is really a bug at all. Maybe MS created some wonderful tool that developers could use to test their applications for different Windows systems. Guess not ^^
