There are many functions in ADSI that may help you. I'm not sure which one would meet your requirements. But as far as I know none of them "force a user's login using Windows authentication". For example:
-Changing Computer Account Attributes
-Copying an Active Directory Computer Account
-Creating a Computer Account For a User
-Deleting a Computer Account
-Enumerating Computer Account Attributes
-Enumerating Computer Accounts in Active Directory
-Joining Computer to a Domain
-Moving a Computer Account
-Renaming a Computer Account
-Renaming a Computer and Computer Account
-Resetting a Computer Account Password
-Searching for Computer Accounts

>We are trying to move from SQL Server to Windows authentication. We have added an Active Directory group that contains all users who have access to the database. We plan to drop all user logins from SQL Server and add the AD group as a SQL Server login. This way we can force strong passwords and the changing of passwords via Active Directory.
