  BCDR (Business Continuity and Disaster Recovery options) is a big deal for any I.T. Pro. My decision to go with with Microsoft Azure Site Recovery cloud service was easy after considering other options available to me, cost and the specific needs of my infrastructure environment. It was by far a better solution in terms of…

• Using NTDSUTIL Metada Cleanup to Remove a Failed/Offline Domain Controller Object.

  In this post, I would like to talk about using the ntdsutil utility for metadata cleanup. A domain controller failure ‘DC00’ recently occurred in my lab. Running the repadmin /replsum command confirmed a replication error and showed DC00 as unavailable: Since a dcpromo was obviously out of the question, I used the Ntdsutil metadata cleanup…

• Configuring a Single Windows Server 2012 R2 Active Directory Domain Controller in a new Forest.

  Pre-Windows Server 2012 and PowerShell 4.0, the primary tool/command for Active Directory Domain Controller promotion and demotion has always been the Dcpromo command. With Windows Server 2012, it’s been replaced by a suite of PowerShell cmdlets contained in the ADDSDeployment module. In this post, I’ll talk about my experience setting up a single WS2012 R2…

• Deploying a Windows Server 2012 R2 Domain Controller in an existing Win2003 Functional Level Domain.

  My first task before deploying a Windows Server 2012 R2 Domain Controller in a Windows Server 2003 forest functional level environment was to run the Test-ADDSDomainControllerInstallation cmdlet and determine my domain environment’s readiness to accept the new Windows Server 2012 R2 Domain Controller installation without any glitches: [ws2012r2]: PS C:\Users\admin\Documents> Test-ADDSDomainControllerInstallation -DomainName genesys.net | fl…

• Seizing Active Directory FSMO (Flexible Single Master Operations ) roles with Powershell.

  I have been running 2 Virtual Machines as Active Directory Domain Controllers in the Lab for sometime now. DC00 was running Windows Server 2003 R2 and DC01 is running Windows Server 2008 R2. But recently I lost a Hyper-v machine hosting DC00 Domain Controller VM, I had no replica available to immediately failover and didn’t…
