1. Connect the Mac with the Windows Server Essentials Connector Connecting that Mac to your Windows Server 2012 R2 Essentials is really easy. Before you start with this procedure you should download the update connector from Download Windows Server Essentials Connector for Windows Server 2012 R2 from Official Microsoft Download Center . The last version is also compatible with the latest version of Apple Macintosh OS X. Open Safari and browse to http://servername/connect . Click on download software for Mac. Open ‘Connector for Mac’ to install it. Click Open. Use the username and password of your Mac Click Continue You can use the name of your server if DNS is working or use the IP address. Click Continue. Give your Mac a name to identify it on the Microsoft network. Now you need the credentials of the administrator of the Microsoft Windows Server 2012 R2 Essentials. We need to another description of this Mac. The Windows Server Launchpad is handy so I leave it checked. Click Close Use your Windows credentials to sign in to the Windows Server 2012 R2 Essentials network. We can go to the shared folders and if you are also an admin on the Windows server you can view alerts on the server. 2. Join the Mac to a Windows Domain the classic way As we have found that the Connector not really joins the Mac to our Windows Server 2012 R2 Essentials comain it is now time to use the classic procedure. I prefer this method because it allows me to use a domain account to authenticate with the Mac. Now that we have found that our Mac is not really joined to the domain we want to really join it and authenticate against the Active Directory when we login. Choose Users & Groups. Click the lock to unlock. Use a local Mac administrative account for this. Click Join. I am going to use the same name as we did when we connected the laptop to the Windows domain with the connector. I do this because I run the ‘classic join method’ now and hope to maintain the use of the Launchpad. This laptop has already a computer account in the Active Directory with the name ‘mac0001’. Click OK. Change ‘Display login windows as’ to ‘Name and password’. Click Options. Click ‘Only these network users’, click the +sign and choose the user(s) you want add. Make sure to change this in a checkmark, after that click the lock to prevent further changes. Logoff and login with your domain credentials Because you have used your domain credentials you can add a connection to your server shares without entering credentials. All security is now handled by our Windows Server Essentials and no passwords are stored locally on your Mac. Click on Contososerver All our shares are available.
