Googling the ODBC error code 28000 suggests that this is a login issue (as indicated by the error message itself). That search leads to many articles that you could search for further hints as to what is happening and how to fix it.

Without having a MS SQL Server installation to test with, my best guess is that there are settings when you create a data source that need to be set to appropriately connect to your server, and the server itself will need to have credentials set that the data source can use.

There are also some other items to be aware of when configuring a FlexSim <> ODBC <> DB setup. This may not be affecting you, but I'll mention it in case others searching the community need it.

Make sure that your ODBC driver architecture (32- or 64-bit) matches your FlexSim installation.

The ODBC driver needs to be compatible with your database software. Its possible that if the ODBC driver is 64-bit, it may not be able to talk to a 32-bit database application. See the following articles for related information specifically for MS SQL Server:
- Data Source Names and 64-bit Operating Systems
- Create a 32-bit DSN on 64-bit machine for SQL Server
- How do I connect to my 64-bit SQL Server with ODBC?
- How do I use a 32-bit ODBC driver on a 64-bit Server 2008 when the installer doesn't create a standard DSN?
- That isn't an exhaustive list, but it's a starting point if this seems to be affecting you
