Solution to Windows Virtual Machine in VMWARE which has set up with 8 vCPU only showing only 2 core.


[Problem]
Windows Virtual Machine in VMWARE  which has set up with 8 vCPU only shows 2 core. 


[Instruction]
  1. Power off the virtual machine.
  2. In Virtual Hardware, Enter the number of CPUs. (ex. 8)
  3. Click the VM Options tab.
  4. in the Advanced options section, Click Edit Configuration in Configuration Parameters.
  5. Add cpuid.coresPerSocket in the Name column.
  6. Enter a value (try 2, 4, or 8) in the Value column. (ex. 4)
    Note: Ensure that the number of vCPUs is divisible by the number of  cpuid.coresPerSocket in the virtual machine. That is, when you divide the number of vCPUs by the number of cpuid.coresPerSocket, it must return an integer value. For example, if your virtual machine is created with 8 vCPUs, coresPerSocket can only be 1, 2, 4, or 8.

How to configure LDAPS, LDAP over SSL, using CA Certificate Service on Domain Controller in Windows Server 2016

This post is to provide an instruction on how to set up LDAPS (LDAP over SSL) on Domain Controller using single-tier CA hierachy. Reasons for Enabling LDAPS By default, LDAP communications between client and server applications are not encrypted. This means that it would be possible to use a network monitoring device or software and view the communications traveling between LDAP client and server computers. This is especially problematic when an LDAP simple bind is used because credentials (username and password) is passed over the network unencrypted. This could quickly lead to the compromise of credentials.  Reasons for enabling Lightweight Directory Access Protocol (LDAP) over Secure Sockets Layer (SSL) / Transport Layer Security (TLS) also known as LDAPS include: Some applications authenticate with Active Directory Domain Services (AD DS) through simple BIND. As simple BIND exposes the users’ credentials in clear text, use of Kerberos is preferred. If simp...

Setting up AD LDS on Windows Server 2016

What Is Active Directory Lightweight Directory Services? Microsoft Active Directory Lightweight Directory Services (AD LDS) is an independent mode of Active Directory that provides dedicated directory services for applications. AD LDS is a mode of Active Directory that provides directory services for applications. AD LDS provides dedicated directory services for applications. It provides a data store and services for accessing the data store. It uses standard application programming interfaces (APIs) for accessing the application data. The APIs include those of Active Directory, Active Directory Service Interfaces, Lightweight Data Access Protocol, and System.DirectoryServices. AD LDS operates independently of Active Directory and independently of Active Directory domains or forests. It operates either as a standalone data store, or it operates with replication. Its independence enables local control and autonomy of directory services for specific applications. It al...

What is Active Directory?

Active Directory ( AD ) is a directory service that Microsoft developed for Windows domain networks. It is included in most Windows Server operating systems as a set of processes and services. Initially, Active Directory was only in charge of centralized domain management. Starting with Windows Server 2008, however, Active Directory became an umbrella title for a broad range of directory-based identity-related services. A server running Active Directory Domain Services (AD DS) is called a domain controller. It authenticates and authorizes all users and computers in a Windows domain type network—assigning and enforcing security policies for all computers and installing or updating software. For example, when a user logs into a computer that is part of a Windows domain, Active Directory checks the submitted password and determines whether the user is a system administrator or normal user. Also, it allows management and storage of information at admin level and provides authenti...
