Hi Ionara,
The creator and editor fields should not be changing to blank after a synchronization. What version of ArcGIS for Server are you using, and what database? (i.e ArcGIS for Server 10.1 SP1, SQL Server 2008)
The reason the new features you create have ESRI_Anonymous is because you are editing a non-secured service. When editing a feature service, editor tracking uses ArcGIS for Server's credentials, not your geodatabase credentials. For example, if you secure the service with a username/password, you will need to enter these credentials to access the service. These are the credentials that will be stored in the editor tracking fields.
