I have many layers that have joins to MYSQL tables. I have all the ODBC connections set up in Arc Catalog, and in Arc Map everything works as it should. When I go to publish the service it wants me to register the databases. When I try to register it, it comes back with 'error: general function failure'. I have tried to register the database from manager, but when I import the connection file it just hangs until I close it. Any help would be very appreciated.
