I am building Group Policy for a new domain that we are migrating to. In our current environment the settings Log on as a Service is set at the Server OU level - which has about a hundred Service Accounts in that field for having access to this right. I would like to set this lower down our OU tree structure we separate out servers based on the application that they runbut a couple of our internal staff have want to not set this policy at all.

IE: not checking the setting in Group Policy and let the local servers deal with what accounts are put into its local policy for this setting. Our internal security team want it set as I do, but the couple of people who don't want it set includes an Architect - hence the conflict.

I have consulted with Microsoft Premier Support who didn't have an official answer for meinternal staff, external IT friend staff, and hours of internet research - but I cannot find any information on if this policy should be set at all. My instincts are to manage this via GPO so that it can be easily audited and managed from one place our company goes through various external audits from time to time. This seems a bit ambiguous to me The article you linked provides an explanation of what rights Log on as a Service provides:.

The Log on as a service user right allows accounts to start network services or services that run continuously on a computer, even when no one is logged on to the console. In short, you only want to provide this right to the accounts that need it - by default, that's the Local System, Local Service and Network Service accounts, because those are what services run under by default.

If you wish to run a service under a different security context like a service account you createyou would want to grant that service account Log on as a Service rights so that it could run your service without the need for a user to be logged in.

NET as examples where additional accounts are granted this right; it applies to third-party programs that run as services as well. So, the best practice is to assign this right only to accounts that services run under, and to run individual services under service accounts that are configured according to principle of least privilege only give them permissions they need to run; don't give them admin or SYSTEM privileges.

9 Tips for Preventing Active Directory Service Accounts Misuse

I would add that controlling this by GPO is the more secure approach. If it's controlled locally on each server, then anyone who gets Administrative rights on a server can control what accounts can run services on that server, whereas enforcing it via GPO requires getting the appropriate domain rights at a domain level. By default, no accounts have the privilege to log on as a service. Accounts that aren't in that list shouldn't be able to log in as a service, so if you clear the list, your services with service accounts shouldn't be able to start anymore.

I tend to create a service account group and put that into the policy. It reduces the number of times I need to make changes to the policy itself. And, as you said, it's way easier to audit than letting it get set server to server.

I am trying to implement a technical control in our environment so that certain AD accounts are restricted from logging onto a workstation locally, but the account should be allowed to use the "Run As" function. I thought about implementing the "Deny Logon Locally" GPO thought User rights assignment, but the problem is that these are privilege accounts that users need to elevate permissions to carry out admin functions.

So how can I stop an account from physically logging onto Windows, but the account should be able to use the "Run As"? Learn more. Asked 7 months ago. Active 5 months ago. Viewed 63 times.

Stack Overflow works best with JavaScript enabled.One of the bigger challenges in some Active Directory environments is controlling who is allowed to log into workstations. By default, every user in AD automatically gets added to Domain Users. Domain Users is, once again by default, included in the local Users group on workstations when the workstations get added to AD.

That means that unless you take action on either the user account or the computer configuration, any user account in your AD environment can log into any computer whether you want them to or not. However, in a larger environment, managing individual accounts can be very time consuming, especially if you have to manually specify computer names for every single user account that needs limited access. The good news is that there is a Group Policy setting that works with every version of Windows that can be managed with Group Policy from Windows through Windows 8 that will solve this problem for you.

However, you can use any AD group here. Just as a reference, here is the default configuration for Windows If you happen to be a user that is not authorized to use a computer, here is the message the user will see on Windows XP:. The local policy of this system does not permit you to logon interactively. And here is the error message they will see on Windows Vista or 7 the message is the same for both except for the OS name :.

You cannot log on because the logon method you are using is not allowed on this computer.

Your question was not answered? Ask in the forum! However this doesn't scale well if you have more than 10 Domain Controllers or 10 Domain Admins.

Domain Admins can obviously undo this, but it's more about enforcing best practice on some of your most trusted IT staff. You could also use "Log On To". Then put "Little Johnnie" in a group, and add that group to the local Users group of the computers you want them to have access to. How could I restrict users logon to any other workstation of my Domain environment. I want to allow every user with a definite workstation. Is there any policy? Please help me. It's very urgent need of my organisation.

If you want that each user can only logon to their own computer, you have to configure this in the Account tab in Active Directory Users and Computers for every user as Kyle explained at the beginning of the article. There can't be a policy for this because you obviously have to configure this somewhere for each user separately. If you have many users, you could name the computers after their users and then write a PowerShell script that modifies the corresponding user object attribute in AD.

Yet another option is to explain to your management that if users only store files in their user profile, it is not really a problem if users can log on to other machines because Windows ensures that a user's files are only accessible by the profile owner and admins, of course.

What exactly isn't working? How is it not working? How are you logging on to these clients? Based on the screenshot, you haven't added any of those local accounts to the list, only a computer account which can't be logged into anyway and the SPDI domain account.

Only accounts that appear in the list will be prevented from logging in. So at the moment SPDI is the only account that will be prevented from logging in. Active Oldest Votes.

This may or may not be the best way of dealing with this, but it does solve a need by moving user access to AD vs configuration on local servers. This has resulted in inconsistencies, as one might expect. This can be done via the Local Security Policy secpol. However, there are two obvious issues with this:. While this may be the only way to accomplish this, it is decentralized and uncertain to maintain. Using other methods you can allocate to existing groups with existing rights, but you cannot either dynamically specify a group in THIS GPO location, affect the Local Security Policy, or set the rights for this local group.

The —C must also be used to copy the batch file to the local system so it can run. This is where the magic comes in. Instead, place your cursor in the NAME field. Press the F3 key :. This will limit impact during testing. There you have it.

Equally, a PSEXEC run against all servers in the domain could force set this group on a periodic basis to ensure the rights existed. Additional error checking could be built in to check if the command was successful, check if the domain group exists, create it if required, etc. You are commenting using your WordPress.

This would be a company policy scenario, and would ensure that administration and auditing of local group memberships was ONLY done via Active Directory, and could be done via delegated rights by users who may not have rights to login to the server.

Email required Address never made public. Name required.From a security point of view, it is always recommended to use special service accounts to run application services instead of system accounts. The reason being, if a service account is compromised, the losses will be limited compared to a system account. The security of Service Accounts in Active Directory is important and there are some simple things you can do to ensure it.

Here are nine tips to prevent the misuse of service accounts and keep them secure:. When creating a service account, always keep in mind that it should only have the minimum privilege required to complete the task at hand. For example, a few additional privileges that you can shed are remote access functionality, terminal service logons, internet and email access and remote control rights.

All these settings can be configured easily. Figure 1: Denying unnecessary privileges. In some of the past cases of service account misuse, it was found that the accounts had extra privileges because they were created by copying old accounts with high privileges.

Copying lightens the administrative burden, but it comes with a risk! Assigning service accounts in built-in privileged groups, such as the local Administrators or Domain Admins group, can be risky. Additionally, tracking the offender will be difficult as several administrators in that group will know the credentials.

If, for some reason, you have to assign a service account to a privileged group, then create a custom group and add the service account to that instead.

Then, explicitly deny access to other accounts for that group. Such measures will eliminate the possibilities of service account misuse. After performing the above steps, permissions inherited from the parent are overridden. This way, even if the service account is compromised, vital resources will not be accessible to hackers.

Review and eliminate unnecessary user rights. To implement this, create a custom Group Policy Object GPO at domain level that denies a service account the right to log on through the network or as a batch job.

The steps are shown in the following image:. This way, service accounts will not be able to access file servers with sensitive data. Figure 6: Account Tab of User Properties. Figure 7: Add Workstations. Here you can add the name of those computers, on which any user with the selected Service Account can login. This service account will not work on other computers that are not listed here.
