As you may know, Active Directory\u00a0provides authentication and authorization mechanisms as well as framework from within other related services that can be deployed.\u00a0As an LDAP compliant database, it contains most commonly used objects such as users, computers, and groups which can be organized into organizational units or OUs by any number of logical or business needs. Group Policy Objects or GPOs\u00a0are then\u00a0linked to OUs to centralize the settings for various users or computers across an organization. Part of the quandaries that IT professionals face is taking advantage of nuances provided\u00a0in Active Directory in newer server offerings such as Windows Server 2012.\u00a0 As detailed in Pierre’s post, “Windows Server 2012 Active Directory \u2013 What\u2019s New?”<\/a>, Active Directory provided in Windows Server 2012 is provided\u00a0impactful enhancements.\u00a0 Yet\u00a0some organizations choose not to migrate due to reasons of uncertainty.<\/p>\n

This Step-By-Step,\u00a0suggestion online via the\u00a0IT Professionals Community of Greater Toronto<\/a>,\u00a0is\u00a0to help deal with that uncertainty and provide guidance for IT professionals looking to migrate their organizations Active Directory offering from Windows Server 2003 to 2012.<\/p>\n

              Removing the 2003 Windows Server from the Global Catalog Server<\/strong><\/p>\n

                \n<\/strong><\/li>\n
              10. In the Network and Sharing Center<\/strong>, be sure to change the Preferred DNS server to match the Alternate DNS server, then delete the IP address listed under the Alternate DNS server\u00a0should it currently be pointed to the old 2003 Windows Server.<\/li>\n<\/ol>\n

                 <\/p>\n

                All that’s left is to demote the old 2003 Windows server by first adding the new 2012 Windows Server as the Primary DNS, followed by running DCPROMO to demote the old 2003 Windows server.<\/p>\n","protected":false},"excerpt":{"rendered":"
