The ping fails. Basicly it looks like cadstuff (the license server)
asks for an address, dhcp assigns it, but cadstuff doesn't do anything
with it except ask again a few hours later. Oh, and it doesn't just ask
once, noooo, it asks twice and of course gets two addresses allocated!
The problem may be fixed now but unfortunatly it appears to be a mystery
fix. We turned off the dhcp client on cadstuff with no effect but upon
reboot it doesn't appear to broadcasting anymore requests. We'll know
for sure on friday morning if it really worked.
