Assembly failed

Hi, I am trying to assemble some components and they keep failing.

The error message is

Info:Starting Step Check-assembly at 2005-07-25 05:01:03.0136 +2:00
Fatal:Contact CBS administrator: Nonempty list of broken DCs -stopping export now
Error:list of broken DCs:

Error:sap.com,home/xbtrwebservices
Info:Step Check-assembly ended with result 'fatal error' ,stopping execution at 2005-07-25 05:01:03.0464 +2:00

However the build is ok.

Can anyone please advise, this is really urgent

Thanks in advance.
