Extensible Authentication Protocol - Windows 7 Service

• Windows 7 Authentication Error
• Authenticate Windows 7 Ultimate Iso
• Authenticate Windows 10 Free

The Extensible Authentication Protocol (EAP) service provides network authentication in such scenarios as 802.1x wired and wireless, VPN, and Network Access Protection (NAP). EAP also provides application programming interfaces (APIs) that are used by network access clients, including wireless and VPN clients, during the authentication process. If you disable this service, your computer is prevented from accessing networks that require EAP authentication.

Windows 7 Authentication Error

Fixes a Windows 7 SP1 or Windows Server 2008 R2 SP1 issue where 802.1X authentication fails intermittently after you connect the computer to a network that uses IEEE 802.1X authentication. This issue occurs when you set up the connection by using a device that supports the 802.1X authentication. Activate Windows 7 using CMD Prompt Step 1. Go to start menu and search cmd, then right-click on it and select Run As Administrator.

This service also exists in Windows 10, 8, Vista and XP.

Startup Type

Default Properties

Default Behavior

The Extensible Authentication Protocol service runs as localSystem in a shared process. It shares an executable file with other services. If the Extensible Authentication Protocol fails to load or initialize, the error is recorded into the Event Log. Windows 7 startup should proceed, but a message box is displayed informing you that the EapHost service has failed to start.

Dependencies

Extensible Authentication Protocol will not start, if the following services are stopped or disabled:

If the Extensible Authentication Protocol is stopped, the following services will not start and initialize:

Automated Restore

1. Select your Windows 7 edition and Service Pack, and then click on the Download button below.

2. Save the RestoreExtensibleAuthenticationProtocolWindows7.bat file to any folder on your hard drive.

3. Right-click the downloaded batch file and select Run as administrator.

4. Restart the computer to save changes.

Note. Make sure that the eapsvc.dll file exists in the %WinDir%System32 folder. If this file is missing you can try to restore it from your Windows 7 installation media.

In a network environment, user authentication can be handled by one of several methodsdepending on whether Active Directory is enabled. If Active Directory is not beingused, then authentication is handled at a more basic level. If Active Directory is in use,then several more advanced authentication techniques are available in Windows Server2008. If users are coming in over the Internet, they can use certificates and the SecureSockets Layer (SSL) or Transport Layer Security (TLS) protocols for authentication. In thecase of certificates, Windows Server 2008 can take an authenticated certificate and map itto a user account for integration with the rest of the system (see 'Certificate Authentication,' later in this tutorial).

In all these methods, a user account must first be established on the server before authenticationcan be accomplished. Without Active Directory, the procedure for setting upa user account is exactly the same as with the local computer, discussed in the precedingsection, except that it must be done on each server in the network. With Active Directoryand Active Directory Certificate Services, all of which require Active Directory for fulluse, the procedure is a little different. Here are the steps:

Authenticate Windows 10 Free

1. Click Start | Administrative Tools | Active Directory Users And Computers. The Active Directory Users And Computers dialog box opens.
2. In the left pane, open the applicable domain and then the Users folder. Click the Action menu and click New | User.
3. In the New Object - User dialog box, enter the user's name and username, as you can see here, and then click Next.
4. Enter and confirm the password, choose how you want the user to change the password, and then click Next.
5. Review your choices, use Back if you need to make any changes, and click Finish when the account is the way you want it.

By establishing this one user account in Active Directory, with the appropriate policies,the user can sign on anywhere on the network, which may extend over the Internet, and be authenticated.

Kerberos Authentication

Kerberos Version 5 is the default authentication protocol in Windows Server 2008, andKerberos, in several versions, is the default authentication protocol over much of theInternet. This means that the same authentication routines in Windows Server 2008 canvalidate both a local Windows Server 2008 client and an Internet-connected UNIX client.Kerberos was originally developed by MIT for Internet authentication (http://web.mit.edu/kerberos/www/). The specification for Kerberos Version 5 is maintained by theInternet Engineering Task Force (IETF) and, along with an overview, is contained inRequest for Comment 1510, which is available online at http://www.ietf.org/rfc/rfc1510.txt.

In addition to commonality with the Internet and numerous systems, Kerberosprovides another major benefit to Windows Server 2008 users. In other authenticationschemes, each time a user attempts to access a different network service, that service hasto go to the authentication server to confirm the authenticity of the user. This doesn'tmean the user has to log on again, but each service has to get its own confirmation, creatinga fair amount of network traffic. That is not the case with Kerberos, which provideseach user with an encrypted ticket with the user ID and password that network devicescan use both for identity and for validity. The Kerberos ticket system also validates thenetwork service to the user, providing mutual authentication between user and service.

NOTE: The Kerberos ticket is also referred to as a service ticket or as a user ticket. They are all the same object.

Kerberos uses a Key Distribution Center (KDC) on each domain controller that storesthe user accounts that have been entered into the network's Active Directory. When a userattempts to log on and use any part of the network, the following process takes place:

1. The username and password are encrypted and sent to the KDC.
2. The KDC validates the username/password combination.
3. A ticket is constructed containing the encrypted username and password plusan encryption key that can be used to transfer information between the user and any network service.
4. The ticket is returned to the user's point of logging on, where it is presented tothe network service, thereby proving the authenticity of the user.
5. The ability of the service to accept and utilize the ticket proves the authenticity of the service to the user.
6. Any information transferred between the user and the service is done using the encryption key in the ticket.
7. If, while still logged onto the first network service, the user reaches out toanother network service, the ticket is automatically presented to the secondservice, providing immediate mutual authentication and the ability to securely transfer information.

You can see in the preceding steps another major benefit to Kerberos: the inclusionof an encryption key in the ticket that allows the user and a network service to securelytransfer information. This automatically solves another of the security demands, securing data transmission.

Kerberos is a very powerful means for authentication and a major asset to Windows Server 2008.
