* [[Internet Information Services]] 8.5: Support for logging to [[Event Tracing for Windows]] and the ability to log any request/response headers. To improve scalability, if IIS is configured with 100 or more web sites, by default it will not automatically start any of them. Alongside this, a new "Idle Worker Process Page-Out" configuration option has been added to application pools to instruct Windows to page-out the process if it has been idle for the idle time-out period (by default, 20 minutes).<ref>{{cite web|url=http://www.iis.net/learn/get-started/whats-new-in-iis-85|title=What's New in IIS 8.5?|publisher=Microsoft}}</ref>

* IP Address Management (IPAM): Extended to support [[role-based access control]], allowing for fine-grained control over which users can view or change configurations for DHCP reservations, scopes, IP address blocks, DNS resource records, etc. Additionally, IPAM can integrate with [[System Center Virtual Machine Manager|System Center Virtual Machine Manager 2012 R2]] to have coordinated IP policy across both physical and virtual environments. The IPAM database can be stored in a [[Microsoft SQL Server|SQL Server]] instance instead of [[Windows Internal Database]].<ref>{{cite web|url=http://technet.microsoft.com/en-us/library/dn268500.aspx|title=What's New in IPAM in Windows Server 2012 R2}}</ref>
* [[Group Policy]] has a new "Policy Cache" setting which allows ___domain-joined machines to store a copy of the group policy settings on the client machine and, depending on the speed of access to the ___domain controller, use those at startup time instead of waiting for the policy settings to download. This can improve startup times on machines that are disconnected from the company network.<ref>{{cite web|url=http://technet.microsoft.com/en-us/library/dn265973.aspx|title=What's New in Group Policy in Windows Server 2012 R2|publisher=Microsoft}}</ref> New Group Policy settings have been added to cover new features in Windows 8.1 and [[Internet Explorer 11]], such as enabling/disabling SPDY/3 support, configuring start screen layouts, and detecting phone numbers in web pages.<ref>{{cite web|url=http://www.grouppolicy.biz/2013/06/whats-new-in-group-policy-in-windows-server-2012-r2/|title=What’s new in Group Policy in Windows Server 2012 R2|publisher=Group Policy Central}}</ref>
* [[Transport layer security|TLS]] support is extended to support RFC 5077, "Transport Layer Security (TLS) Session Resumption without Server-Side State", which improves performance of long-running TLS-secured connections that need to reconnect due to session expiration.
* [[Hyper-V]] role and Hyper-V management console are added to the Essentials edition.<ref>{{cite web |url=http://blogs.technet.com/b/sbs/archive/2013/09/03/understanding-licensing-for-windows-server-2012-r2-essentials-and-the-windows-server-essentials-experience-role.aspx |title=Understanding Licensing for Windows Server 2012 R2 Essentials and the Windows Server Essentials Experience role |work=The Windows Server Essentials and Small Business Server Blog |first=David |last=Fabritius |date=3 September 2013}}</ref>
