Yes you will have to disable the sync check in the server.ini. Or not freeze the registry.
1. Stop the ePO Services
2. Add the following to the server.ini (under the server section)
3. Restart the epo Services.
You will have to have patch 5 or 6 on the epo server as well for this feature to work.
Thanks a lot, this is doing the trick without any apparent drawback. The errors are still occuring but they no longer disturb the console.
