yesterday I installed SLES11SP3-PPC and registered the system without
regcode. Today I want to reregister with the now known regcode. But I
get the message:"None of the installed products can be registered at
the Novell registration server (100)"

Even if I try to register an other system (SLES11SP2-x86_64) I get the
same message.

If I try to browse to https://nu.novell.com/repo/$RCE/ I have to
authenticate with my mirror credentials but after this I get an 'Access

Is the nu.novell.com down? What happens?
