When I click on Synchronize now I get the following error:

Synchronization failed for:
Open Enterprise Server Linux http://sdb.suse.de/download/
SUSE CORE 9 http://sdb.suse.de/download
Check whether the requested server is up. If yes,
make sure theat the user name and the password
are set correctly (see 'Edit' dialog).

I click on the 'Edit' dialog and both URL's are set to Anonymous.
know of any alternate URL's that I can check for updates?
