ODBCConnection Issue when Opening the connection

I'm having some issues with a windows service that I have running. I've created a new test service that creates an ODBCConnection with a connection string that I have verified many times to be correct. Whenever I call the Open() method, I get the following error:

Error: System.Data.Odbc.OdbcException (0x80131937): ERROR [08001] [Simba][SimbaEngine ODBC         Driver][DRM File Library]Invalid account name.
ERROR [IM006] [Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed

I have the service running in 32 bit mode and the DSN is created in the 32-bit ODBC Administration tool. I am able to connect using an ODBC tester with the same connection string. I can also run the service through a command prompt and it will work perfectly. I have tried running the service as a user with the highest permissions, but that didn't help. Does anyone have any ideas on what could be causing this?

Here is the code that is running. I made it very basic to remove other factors:

string connectionString = "verified connection string";
string query = "random query I know works";
OdbcConnection c = new OdbcConnection(connectionString);
 try
    {
        elog.WriteEntry("Opening odbc connection...", EventLogEntryType.Information);
        c.Open();
        elog.WriteEntry("Opened odbc connection...", EventLogEntryType.Information);
    }
    catch
    {
        c.Dispose();
        throw;
    }
