Overal I like the new EMC. But in my opinion it's difficult to compare ESM with EMC because in ESM it was possible to configure nearly every parameter of a server. In EMC you can only configure the "important" stuff. For all other things you'll have to use the shell. A good example is the Protocol config(SMTP, POP, etc). A real drawback is, that the ADUC extensions are no longer available. I know that it was done because of customer feedback, ease of development, etc. But I have *many* customers which use ADUC to manage the whole user/group stuff. They aren't happy with EMC... My company plans to release an extension to ADUC which will "emulate" the behavior of the E2003 Extensions...
