How to find NT ServiceMSSQLSERVER and NT ServiceSQLSERVERAGENT accounts?
- Get the properties of the services.
- Easiest way is, just type the account and leave the password blank.
- Click on to get the service restarted.

31. The support lifecycle for Microsoft Windows NT 4.0 Workstation ended June 30. Microsoft is retiring support for these products because the technology is outdated and can expose customers to security risks.
Microsoft has revealed that the upcoming release of Windows 10 will include a change that makes the Windows NT kernel jump to version 10.0. It left software like Windows 2000 with the 5.0 version number after years of Windows 2.0, 3.0, 3.11, and 4.0 releases eventually merging alongside versions like Windows 95 and 98.
Log in to SQL Server Management Studio. Add 'NT AUTHORITYNETWORK SERVICE' as a login under Security > Logins > New Login Under the 'User Mapping for the Network Service' account, add the following database role membership for the SQL Database that will be used to store ArcGIS Server users and roles.
There are actually two versions of Windows NT: Windows NT Server, designed to act as a server in networks, and Windows NT Workstation for stand-alone or client workstations.
ALL SERVICES is a well-known security identifier, whose membership is implicit based on rules that are hard-coded into the operating system. That is, you can't add or remove users, the security identifier is assigned automatically to the appropriate users or in the appropriate situation.
The NT SERVICESQLSERVERAGENT login is how the Windows process that is SQL Server Agent connects to the Database Engine to read the msdb database to find out what it should do; and then do it. Both of these logins are members of the sysadmin fixed server role, so they can do anything in the Database Engine.
A. NT actually stands for Northern Telecom but Microsoft licensed it and in the Windows sense stands for New Technology. Its also interesting to note its heritage.
Windows NT is a Microsoft Windows personal computer operating system designed for users and businesses needing advanced capability. NT's technology is the base for the Microsoft successor operating system, Windows 2000.
In Windows NT operating systems, a Windows service is a computer program that operates in the background. It is similar in concept to a Unix daemon. Windows NT operating systems include numerous services which run in context of three user accounts: System, Network Service and Local Service.

If you're using Kerberos, then you'll see the activity in the event log. If you are passing your credentials and you don't see any Kerberos activity in the event log, then you're using NTLM. Second way, you can use the klist.exe utility to see your current Kerberos tickets.
Kerberos is most definately running if its a deploy Active Directory Domain Controller. Assuming you're auditing logon events, check your security event log and look for 540 events. They will tell you whether a specific authentication was done with Kerberos or NTLM.
In the "Network Security: Restrict NTLM: NTLM authentication in this domain" policy property window, click the drop-down menu and select the option titled "Disable" and then Click "OK".
How to Configure NTLM Authentication
- Go to USERS > External Authentication.
- Click the NTLM tab.
- Enter the NTLM/Kerberos realm name in the Domain Realm field.
- Enter the Netbios Domain Name.
- (Optional) Enter the MS Active Directory Workgroup Name.
- In the Domain Controller field, enter the hostname or IP address of the domain controller.
NTLM — Uses an encrypted challenge/response that includes a hash of the password. Basic — Prompts the user for a username and password to authenticate the user against the Windows Active Directory.
NTLM credentials are based on data obtained during the interactive logon process and consist of a domain name, a user name, and a one-way hash of the user's password. NTLM uses an encrypted challenge/response protocol to authenticate a user without sending the user's password over the wire.
The main risk of disabling NTLM is the potential usage of legacy or incorrectly configured applications that can still use NTLM authentication. In this case, you will have to update or configure them in a special way to switch to Kerberos.
Current applicationsNTLM authentication is also used for local logon authentication on non-domain controllers. Kerberos version 5 authentication is the preferred authentication method for Active Directory environments, but a non-Microsoft or Microsoft application might still use NTLM.
Kerberos has three parts: a client, server, and trusted third party (KDC) to mediate between them.
On the taskbar, click Start, and then click Control Panel. In Control Panel, click Programs and Features, and then click Turn Windows Features on or off. Expand Internet Information Services, then World Wide Web Services, then Security. Select Windows Authentication, and then click OK.
LDAP (Lightweight Directory Access Protocol) is an open and cross platform protocol used for directory services authentication. LDAP provides the communication language that applications use to communicate with other directory services servers.
It works as follows: Negotiation: The user's system (client) sends a login request to the IIS server. Authentication: The client generates and hashes a response and sends it to the IIS server. The server receives the challenge-hashed response and compares it to what it knows to be the appropriate response.
Definition: Authentication is the process of recognizing a user's identity. It is the mechanism of associating an incoming request with a set of identifying credentials. The credential often takes the form of a password, which is a secret and known only to the individual and the system.
The Windows operating system implements a default set of authentication protocols, including Kerberos, NTLM, Transport Layer Security/Secure Sockets Layer (TLS/SSL), and Digest, as part of an extensible architecture.
Kerberos is a computer network security protocol that authenticates service requests between two or more trusted hosts across an untrusted network, like the internet. It uses secret-key cryptography and a trusted third party for authenticating client-server applications and verifying users' identities.

SQL Server supports two authentication modes, Windows authentication mode and mixed mode. Windows authentication is the default, and is often referred to as integrated security because this SQL Server security model is tightly integrated with Windows.
