How to determine the "exact/complete" version of Windows Server 2003

I need to know the "exact" + "complete" version of the Windows Server 2003 OS I am running.

I have followed the (internet) wisdom - but the answers are not complete.
For example (server machine-01):
The information source displays "Windows Server 2003 Enterprise Edition" but no mention of "R2" (or whether it is x32 or x64) - I know it is "R2" because I installed "R2" on the machine.  I also know it is x32 but, it would be nice if the information source displayed this.

Thanks in advance for the help,
Slator

To verify if this server is R2, you may run the command "winver". A dialog
box will appear showing detailed version information of this computer. If
it says Windows Server 2003 R2, then we know this is a R2 server. What's
more, if you want to determine which version of Windows Server 2003 R2 this
server is running on, you may check the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ServerAppliance\Edition. For more
information, please refer to the following KB article:

Since you list SBS in your zones, I can enlighten you on a few things:
1) The computer properties page will tell you if you are running 2003 or 2003 R2. The reason you aren't seeing R2 in your situation is because SBS 2003 R2 was built on Windows 2003, NOT Windows 2003 R2. So the underlying OS under SBS 2003 R2 is Windows 2003 (R1) and is thus being reported as such.
2) There is no 64-bit version of SBS 2003.
3) When a x64 OS is being run, that too is listed as part of the OS name under system properties. If you don't see x64, you can assume you are running a 32-bit OS.

P.S.  I have done some "preliminary" testing and it looks like the "results" are going to be interesting...
