Thanks ecperez. Important to know the build number to ensure I got the final build.
Build 2542 was the last build that testers would receive. On Monday, August 20, build 2454 was forked to build 2600, and the company began hammering away at this final build for RTM, alerting the press about its progress and explaining the remainder of the schedule. And on Friday, August 24, 2001, build 2600 was declared as RTM as promised, and handed off to PC makers at a media event held on the Microsoft campus.
Hope nothing weird happens like that to Windows Server 2003.
