How can we give permissions for a user to access only a particular machine

Hi,

What is the option in ADS where we can specify that a user only can login to his machine .This will improve the security in the company that we have track on all the events.Can you tell me what will be the disadvntages in doing this.

Please give me a link in performing this.

Regards

Open the user's properties in Active Directory Users & Computers, open the Account tab then click the Log on to... button, you can specify a list of computers the user can log on to from there.

Disadvantages?  Depends on your scenario.  If it's like most offices where everybody pretty much has their own PC the only disadvantage is your effort of filling in who can use which PC, other then that it's a security improvement as you say.  If users roam around PCs in your office the disadvantages are that you'll have to add most PCs to the "allowed list" for each user so you almost negate the security benefits of the exercise and make a lot of work for yourself.

I'm a bit confused what you're asking?

Assuming your asking if you can add a particular user to all computers with a script, I don't know how to do it unfortuantely.  You can make lots of changes to users with the "dsmod" command line tool, but changing the computers they're allowed to log on to isn't one of the options you can change.  There may be a lower-level tool (command line version of ADSIEdit) that could manage it but I'm not aware of it.  It may be possible to do it through Group Policy either, but I've never tried so am not sure how you would go about it.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

To add one computer to multiple users - In Active Directory Users & Computers select all the users you want to add the computer to using the CTRL key and the left mouse button.  Then right click one of the selected users and select Properties. Open the Account tab. Put a tick beside "Computer Restrictions"then press the "Log on to..." button and add the computer there that all these users should be able to use.  All selected accounts will be updated with this computer in their lists.

There's no certain way for Active Directory to know which computer a user uses "usually" so you're going to have to configure this initial bit manually IMHO.
