Join now to read essay Z.E.N Works
Zero Effort Networks (Z.E.N. works) is a great new tool in NetWare 5, that makes the network administrator’s job a lot easier by allowing him to spend less time at each user workstation. To be able to use the Z.E.N. works these are the minimum hardware requirements:

Another utility that is included in Z.E.N. works to help the distribution and management of applications is the Application Launcher, which consists of four major components:
Snap-in DLL

Application objects in the NDS tree
Application Launcher Window and Application object
