    Yes, laptop can be joined to domain
    Yes, it is VERY good practice
    User logon details are cached on the laptop (as long as not disabled through Group Policy) so user can log on with current credentials even when off the corporate network

      Hi,

      yes laptop cld join domain controller.
      You can use domain resources easily if you are joined in domain.
      you can login to laptop only when you are away from domain controller.

      Thanks

            Don't forget you must have an operating system on the laptop that has the ability to join a Domain. eg XP Home cannot join a Domain whereas XP Pro can. Vista and Windows 7 also have similar abilities.
            1 1 was a racehorse.
            2 2 was 1 2.
            1 1 1 1 race 1 day,
            2 2 1 1 2

                  Not really, It could be a missinterpretation of the Cached domain logon information.
                  In all the OS prior to win 2008 the default value of the logon info cashed is 10 and in win 2008 is 25.
                  That means that the last 10 (25) logons will be cached, although the value can be changed from 0 (Disabled) to 50 through Registry or Group policy as mentioned by Ossian.

                    hi L4ndy thanks
                    so it caches 10 (25) LOGONS what will happen in 11th and 26th logon
                    can't we logon after 10th and (25th) times.
                    thanks

                      How long are your machines going to be away from the domain for?

                        Yes you can, for as long as you want. There is no time limit when logging on using cached domain credentials.
                        I think this is where you are getting confused. Let me explain it briefly.
                        If the PC can contact the Authenticating DC and user logs in with valid credentials, then this info gets cached locally on the PC. If the default settings are left then up to 10 logon info is cached and overwritten. When off the domain, when attempting to logon with one of the user credentials cached, then you would be able to do so for as long as you want without a time limit.
                        Hope that sheds more light.
