MWS not starting up


I have a new SQL Server 2008 database which I want to use with MWS 7.1.2. I am trying to configure it with wM database configurator tool. I have only windows authentication access to the db. When I try to run wM database configurator tool, it gives the error as :

sag-cjdbc42-0011][SQLServer JDBC Driver]NTLM (type-2) Authentication was requested but the required DDJDBCAuth05.dll was not found on the path specified by the java.library.path system property.

I have already applied the hotfix as suggested by SAG and upgraded JDBC driver to 4.2.

When I try bring up MWS, it says schema cannot be found.

Can someone suggest what can be done on this?
Also, from where can we download DDJDBCAuth05.dll?

PS: I have included AuthenticationMode:true while forming the db url.
