Windows 2000 build 2120 is a build of Windows 2000 that is mentioned in a file titled MTB Fall 1999 Hands-on Lab: Frequently Asked Questions on the CD for MTB Fall 99.

Q: Why do the labs run Exchange Platinum on Windows 2000 build 2120, rather than a “major” build, such as one of the Beta releases?
A: Interim builds of Exchange Platinum, such as build 4035, are typically verified using a small set of interim builds of Windows 2000. At the time of this writing, build 2120 is the best platform for Exchange Platinum build 4035.
