Just to add my 2cp, I ran a server on Windows Server 2003 (Std) that had 40 static and 10 dynamic zones running for weeks. I never saw excessive RAM usage like you are describing. The only time I saw a real problem was with CPU utilization when I turned on mlog stuff (causes zone.exe to hit 99% and stay there). This was a while ago, though. I can set up my Windows server again with some newer binaries and see if it happens like you describe.
