When your DB Server only supports windows authentification it is possible that you get an error while starting JobScheduler like this
Z-JAVA-105 Java exception java.sql.SQLException("I/O Error: SSO Failed: Native SSPI library not loaded. Check the java.library.path system property.
SSO Failed: Native SSPI library not loaded. Check the java.library.path system property."), method=connect []
This error occurs, when the jTDS driver is used. To solve the problem please downlaod the driver with your actual version http://sourceforge.net/projects/jtds/files/jtds. In the zip file there is a file named ntlm.dll in the folder x86/SSO. Please copy this DLL file to jre/bin of the JVM used by JobScheduler. Restart JobScheduler.
