From ZENworks 24.2 release onwards, the support for Windows server as ZENworks Primary Server has been stopped. Now, you will have two options for running the ZENworks Primary Servers:
ZENworks Appliance: This is a SUSE Linux appliance that can run on hypervisors.
SUSE Linux Enterprise Server: You can install the ZENworks Primary Server directly on SLES.
