I use mysql 4.1 alpha on windows 2000 server. I used mysql 4.0 for windows before. I saw many exe file in the \mysql\bin folder. There are many mysqld type .exe files such like mysqld.exe, mysqld-nt.exe, mysqld-max-nt.exe ... etc. They all can provide mysql service. But what is the different between them? Why Winmysqladmin.exe choose mysqld-nt.exe to be the default service provider on mysql 4.0 but choose mysqld-max-nt.exe on 4.1 alpha?
