It is a successor to the
Windows 2000 operating system that can be used both as a server and as a workstation, where a conversion may be done (although undesirable at the registry level - you essentially get a bloated XP then) by hand, preferably. The system runs indeed smoothly, but only if a person knows what he is doing. The system is more picky on various drivers' defects, so one has to adjust for example the service "Start" type from Auto (2) to On demand (3). The system also accepts nearly all Windows XP drivers (the Compatibility tab helps to the rest) so that no
faux-pas seen on the Windows XP rise vs. older hardware can surprise you. You can download a Service Pack 1 for this system and integrate it into your installation to fix many bugs and enable the
NX bit-based
buffer overrun protection.
To return to the conversion to a desktop environment, I recommend tweaking in gpedit.
msc a lot and copy nusrmgr.cpl from Windows XP to simplify the user management. You use the said Group Policy Editor to remove the "Press
Ctrl+Alt+Delete" nag screen, remove the asking for the reason for shutdown etc.
Right now, I'm running many services and applications on my Windows Server 2003 box. They include all of the common internet services - the web, secure HTTP, FTP, DNS,
DHCP, NAT routing with port forwarding and countless
small ones. As for the user interface (UI), I use StyleXP. All "serious" applications work, I can play GTA:SA, DOOM 3, Manhunt,
Postal 2 and most other such games under this OS.
