aaargh, looks complicated, but this might be it. I wonder, though,  
why our other Dell server doesn't try and pull an IP? Guess there  
must be some configuration difference. I'll give that link to my  
colleague when he's back from his holidays, I don't dare trying  
something like that on the Win server, I have too little experience  
with Windows...

Still, meanwhile, it would be nice to be able and just ignore those  
DISCOVERs... any idea why "ignore booting" is not working?

Thanks for the hint & link,
