Probleme bei Clientinstallation (Netboot Produkte)

[DragonPlayer5588]

Sehr geehrte Damen und Herren,

ich habe gerade folgendes Problem.
Wenn ich einen Client neu installieren will, schlägt das netboot paket direkt fehl.
Dabei ist es egal welches Netboot Produkt ich starte.
Im Forum fand ich diesen Thread : viewtopic.php?t=11335
Leider brachte dieser keinen Erfolg.

In den Logs steht nur folgender Eintrag.
