We run eDirectory on SLES 10 with Zenworks 10.3.1 for policy and bundle management.

Currently most device run Novell Client 2 SP1 for Windows 7, but we need to address a bug and must upgrade to IR4. All devices point to a public path on an old NetWare 6.5 server within the Upgrade Agent tab. I can easily drop all the IR4 installation files to this folder and client will prompt to be upgraded, but I'd like to make the process completely silent and automated.

How can I achieve an automated client upgrade process?

As it stands a user is prompted multiple times to confirm installation in addition to Windows UAC asking the user "Are you sure?".
