Security Solutions: Logon authentication

Locked

In this week’s Security Solutions TechMail column, Mike Mullins addresses the Windows NT and Win2K logon authentication schemes for domains that still contain NT domain controllers. Have you had problems with authentication from geographically separated clients? Are your clients and servers still using the default LAN Manager hash for sending and storing passwords? Share your experiences here.

Here are the links to the Microsoft resources mentioned in Michael Mullins’ column:

In reply to Security Solutions: Logon authentication

If I do this on my DC’s, will I have to immediately do it on the PC’s? Or will they still authenitcate? What if I miss a pc, will it still authenitcate?

Thanks
