When the GetHostByName API is used, the Windows 2000 resolver first submits the name query to DNS. If DNS name resolution fails, the resolver checks whether the name is longer than 15 bytes. If it is longer, resolution fails. If not, the resolver then checks whether NetBIOS is running. If it is not running, resolution fails. If it is running, the resolver then tries NetBIOS name resolution.

The Block policy inheritance or No Override options can affect the presence or absence of Group Policy objects in the list of Group Policy objects to be processed, but cannot change their order. Computer policy is processed at startup and then user policy is processed when the user logs on. If user and computer policy settings specify different behavior, the computer policy will generally prevail.

Well-known SIDs are a group of SIDs that identify generic users or generic groups. Their values remain constant across all operating systems.
windows sysadminMicrosoft has some good guidance on this topic, but itâs not always clearly and consistently stated. Hereâs a quick Q&A that might help.

Active Directory ACE (access control entries) are different from your regular ACEs (for example, NTFS), because they can be used to grant permissions only on specific types of objects, and to propagate only to specific types of child objects. My question is - how do I replicate this in PowerShell?

Regardless of what is in the DDC policy. 2) If you do not have delegated rights on the OU, but are listed within the DDC policy, then you can add machines up to the limit of the âms-DS-MachineAccountQuotaâ attribute.
active directory sysadminThere are well known methods for setting Access Control Entries (ACEs) on Active Directory objects using Powershell, which rely on you knowing the schemaIDGUID of the schema object classes you are working with (e.g. User, Computer, Group). Unless you know your way around AD itâs not always immediately obvious where to find the schemaIDGUIDs that you need. To help you with this, Iâve thrown together a couple of PowerShell snippets.

active directory powershell sysadminHereâs a Powershell script I wrote to delegate permissions to a service account to manage user objects within a number of OUs. The script takes as input a file containing the distinguished names (DNs) of the OUs. The approach should be reasonably obvious from the comments in the script. The only complexity comes from having to get the correct System.DirectoryServices syntax for the Access Control Entries (ACEs).
To establish a domain trust or a security channel across a firewall, the following ports must be opened. Be aware that there may be hosts functioning with both client and server roles on both sides of the firewall. Therefore, ports rules may have to be mirrored.

The lastLogon attribute is not designed to provide real time logon information. With default settings in place the lastLogontimeStamp will be 9-14 days behind the current date.
In this article we will look at the different options and approaches available to recover a DC that has a database corruption. In addition, this article outlines, symptoms, causes, and solutions for this scenario.
active directory microsoft sysadminThe process of authenticating the identity of users during log-in is the first step in gaining system access. For local machines that aren't actively participating in a domain, Windows NT LAN Manager protocol is still utilized to verify a user's name and password before granting system access. However, in domain environments, Microsoft has coupled Active Directory closely with Kerberos. Once access is granted, tickets that permit specific access to other system resources within the domain are exchanged.
