Two Server 2003 Enterprise Edition are installed. One is the "old" version and one is the R2 .. Both Volume License ..
Now I try to find a way to check which one is which .. Sorry for the silly question, but I just installed those two machine for testing and try to compare them.
The only significant thing I was able to spot was the post-setup procedure where all incoming connections are blocked until you close that particiular window.
But how can you check later which one is which ?
Systeminfo shows on both
OS Name Microsoft(R) Windows(R) Server 2003, Enterprise Edition
Version 5.2.3790 Service Pack 1 Build 3790
Again, not important, just wondering ...
