I have seen cases where administrators do not plan it well in advance, and later they have to spend hours in redesigning the OU structure.
So when you are designing OU structure, please keep Group Policy in mind. This will make the deployment of GPO complicated. There should be a regular activity to ensure that no object is left in the default container. This will prevent the accidental deletion of a large OU. So please pay proper attention in OU Delegation to restrict control. This is another area which should be planned meticulously. There are few thumb rules which are as follows :.
The members of Universal Groups are part of Global Catalog which will increase the replication load. If you need to use Universal Groups, use them carefully. This will simplify the group management tasks. This will simplify the Folder permission management. This will help other administrators to contact the right person regarding that group.
You should mention the reference number in the comments section of the group. This will be useful during a future audit. By looking at the group name, you should understand which one is the user group, which one is the permission group, which one is Domain Local Group and so on. Typically , your user group should represent a team or group of people who have something in common.
Access Groups are the groups which have specific access on a particular environment. There are multiple benefits of this approach :. Therefore, avoid granting a user group direct access to any object. Instead, configure access groups and nest user groups within access groups. Some of the common use cases of access groups are :. On the contrary, you should restrict to a minimum number of Domain Controllers which are absolutely necessary to manage the workload.
More Domain Controllers mean more attack surface, more complex replication topology and more management overheads. You can monitor the CPU and Memory utilization of existing Domain Controllers during peak hours for some days, to decide whether you need to deploy additional Domain Controllers. If the process lsass. Additionally , users might complain about slow login or login refusal during peak hours. However, please avoid RODC if it is not required. Now, a few points related to Domain Controllers health management.
There are two aspects of Domain Controller's health management. The first aspect is the health of the Domain Controller Server. You can integrate the script with scheduled task.
The script will only display the errors, if there is no error in any DC then the output will be blank. As Active Directory works on multi-master replication model, we should ensure that all Domain Controllers maintain a consistent database. The database consistency of Domain Controllers is one of the key factors of Active Directory health. There are a few best practices, which helps to keep a healthy AD Database up to a great extent :.
The KCC ensures that no domain controllers within a site are 3 hops away from each other. So careful planning is required to ensure that sites replicate with each other within a certain interval.
For a large environment, monitor regular summary report at least twice daily, and monitor full replication report once a day. Store the reports in a single repository for future reference. I have created two PowerShell scripts, one for Replication Summary Report and another for Full replication Report , which would run the report, email the result and store the report in a date-wise folder.
Once you integrate these two scripts with scheduled tasks, no further manual intervention is required. You can also use 3rd party monitoring tools to accomplish this. However, sometimes an error in replication indicates more serious problem including the presence of Lingering Object s in AD Database.
So please do not neglect Replication errors, and try to solve it as early as possible. If not, enable it in the Domain Controller Group Policy. Enabling this policy would help in avoiding the replication of a lingering object between Domain Controllers. If a Domain Controller is powered down for a long time especially beyond its tombstone lifetime , then do not power it on at all.
I have published an article on this topic, where I have published a generic checklist on cleanup tasks. Distribution groups are built primarily to distribute emails. When possible, users should be assigned to distribution groups rather than security groups, since membership in too many security groups could lead to slow logon functionality. On the other hand, security groups allow IT to manage access to shared resources by controlling user and computer access.
Security groups can be used to assign security rights within the AD network. These groups can also be used for email distribution. Each security group is assigned a set of user rights, dictating their abilities within the forest. For example, some groups may be able to restore files, while others are not. These groups give IT control over group policy settings, meaning permissions can be changed across multiple computers. Permissions differ from rights—they apply to shared resources within a domain.
The simplest way to understand permissions is to think of Google Docs. The owner of such a document can decide who has permission to edit their work, who can comment on it, and which parties can merely view the document. Security group permissions are similar. Certain groups may have more access than others when it comes to shared resources. Microsoft has outlined three main scopes within AD:. Groups can also become members of other groups.
This is called group nesting. Nesting is a helpful way to manage your AD based on business roles, functions, and management rules. Before implementing nesting strategies, be sure to follow Active Directory nested groups best practices. In addition to group nesting management tips, there are also many things to keep in mind when it comes to managing your security groups:.
The best way to avoid headaches is to be proactive. If you can take steps to ensure a healthy Active Directory, your chances of a security breach drop significantly. Here are a few AD user management best practices to keep in mind:.
