we do have workstations connected via VPN (Zyxel-Hardware) to our
corporate network. Many of these workstations do not do a login but work
with "workstation only".
For all these workstations, we get a Error 1456 in Console One when we try
to control them remotly.
Whereas workstations that have logged in to one of our corporate NetWare
Servers can be controled by Zenworks.
In our LAN environment, all WS can be controled no matter if they have
logged in or not.

Servers NetWare 6.5 SP2
Zen 4.0 IR 5 (server side and workstation manager)
NetWare Client 4.9 SP2

any suggestions?
would ZEN 6.5 resolve the issue?
