With DHCP Failover, Microsoft’s goal is to change that, and ensure DHCP server service availability at all times. In this blog post we will quickly review the drawbacks of […]

Windows Server 2012 R2 Installation Options

Windows Server 2012 R2 Installation Options

In Windows Server 2008 and 2008 R2, you could not switch between the Server Core and Server With A GUI options, post-installation. If you chose to install Server with a GUI (called Full Installation in 2008/2008R2) or Server Core, you were stuck with your choice, as there were no means to convert between the two different options, post-installation.   With Windows Server 2012 and later, Microsoft added support for post-installation conversion between […]

Configuring NIC Teaming in Server 2012 R2

By utilizing NIC Teaming, also known as load balancing and failover (LBFO), you can combine multiple network interface adapters to create a single logical NIC to provide fault tolerance or bandwidth aggregation for your network connections. Adapters that are members of a NIC team each maintain their own separate physical existence and each connect to separate network cables.   Prior to Windows Server 2012, NIC Teaming was available only through the use of 3rd party […]

Fine-Grained Password Policies in Server 2012 R2

Prior to Windows Server 2012, you had to use PowerShell, ADSI Edit or the Ldifde command-line utility to create the Password Settings Objects that are used to define fine-grained password policies.

Enabling LDAPS with certificate from a 3rd party CA

LDAP over SSL

Occasionally you will have to install appliances and applications, which will not utilize Kerberos, SASL or NTLM to communicate with Active Directory Domain Services. They will rather use simple BIND, which exposes the users’ credentials in clear text. So anyone with malicious intent, can use network monitoring or packet sniffing tools to capture packets of the communication between the Domain Controller and the client, to view the username and password information in […]

You can choose to enable logging locally on a single computer, or you can enable it for several computers, by defining it in a GPO. Enabling logging can be useful in situations where you are trying to find out why […]
