Hi Wolfgang,

I have applied the offline manual above fully for the first time. I was
able to apply it without facing problems. Thanks!

Issue 1:

I noticed when booting in the primary subnet that the pxe menu is
incomplete. It shows ?LTSP thin client? but ?diskless workstation? is
missing. I believe this is as a result of using boot parameter

Do I need to adjust the pxe menu manually? What do I need to do?

Issue 2:

My diskless workstations work just fine. Due to the issue above I can?t
boot as ?diskless workstation? in the primary subnet but it works fine in
the secondary subnet.

However, again I?m facing issues with my thin clients. None of them is
able to boot anymore. The login screen never shows and I get a black
screen. I faced this issue before with a few somehow special hardware thin
clients but now all seem to be affected and on both subnets.

Kind regards,
