  Hello Readers, today we are going to learn how to Fix trust relationship issue between the workstation and the domain. But before jumping into the solution, we need to learn the concept of Secure channel. What is a Secure Channel ? Before understanding the trust relationship issue, you will need to know what is a Secure channel .  Whenever you add a computer or client machine to an Active Directory domain, your computer account gets created in Active Directory.

Hey All, Today we are going to cover an interesting topic to fetch SID of all domain users. What is SID ? SID (Security Identifier ) is an unique id or value assigned to each and every domain object. Each domain object whether its a Group, User account , Computer , OU is assigned with an unique id in order to get identified by a Domain controller. All these SID's are stored in a Security Database. It looks like  S-1-5-32-545 etc. NOTE :   Domain Controller identifies object with their SID and not with the name. In order to understand this concept, open any box which is in Domain and go to any Folder properties , in Security tab you will observe it will show SID something like  S-1-5-32-545  and then it tries to convert it to name. So Lets Begin There are several ways to find the list of SSID's , I will be covering the easiest ones. 1. To get the list of all the domain users and their SSID Get-WmiObject win32_account | Select FullName,Name,SID,Des...
