We've always had issues with creating duplicate and unwanted databases on Now Contact. Eventually people are sync-ing up to different servers and updating the wrong databases. For example a few of our computers have 2 or 3 contact servers that can be updated when there should only be one. We end up solving the problem by doing a complete purge and reinstalling the software. This takes a lot of time and resources and we think that we could avoid the issue if we knew why these extra databases/servers get created.

Any insight?
