I have created a few FileMaker Pro 12 databases with external data source links to SQL Server. If I host them using FileMaker Pro 12 they all work fine, when I host them on FileMaker Server 12 everytime they start I am asked login to the SQL Server by entering an account name and password. No account name and password will work and sometimes I get an ODBC error. Why do the databases work with FileMaker Pro but not FileMaker Server. Any ideas?
