WSUS sync issues after installation of SCCM 2012 SP1; Event ID 6703 SMS_WSUS_SYNC_MANAGER

Issue:

Today I bumped into a strange issue when upgrading SCCM 2012 to SP1. The installation went well and after checking the eventlog everything seemed to run smoothly.

After I changed the WSUS Sync setting of SCCM to every hour (because of Forefront Endpoint Protection) we noticed that the WSUS server didn’t function properly anymore. The Software Update Point gave the following error:
