Environment: Zenworks, windows xp pro sp2 pl (polish)

Some install actions often fail with error: "[DAU] [Error 1008 Calling LoadUserProfile.]" in the zenworks log. In the windows event log I can see error 1505 ("Windows cannot load the user's profile but has logged you on with the default profile for the system.") followed by zenworks error ("Error 1008 Calling LoadUserProfile.").
So far seen it with registry (system) edit, "run script" (as dynamic administrator) and "edit file".
The same workstation sometimes fails, sometimes not. It looks that it happen more often or even exclusively when bundle is set to "force run" (launch schedule) as opposed to launching it by the user.

Anyone can help me with this?
