We started with the StarterPack in '98, NAL window was opened for everyone, and still is! Nice way to centrally control a lot things.
We went a long time with the StartPack, then upgraded to ZfD3.2 -> ZfD4.01 -> ZDM7 where we are going to stay for a while.
SnapShot, the rescue of many things ;D (and creator of some problems later on...)
Imaging & PXE was really nice feature when it came, but it has always had problems with the new hardware support ;/
ofcoz for admins, zen inventory info and remote control features have been a must too.
For some reason, we have had big problems delivering _Novell_ software via Zenworks.. like updating ZfdAgent.. or Groupwise client, argh. One would think that other Novell products would be easy, with ready .aot files and such.
The worst product decision has been the missing support for Vista in ZDM7.
And now there is the all new ZCM...
Well, we are on hold, have to wait and see.
Hope to see many more years ;D
