• 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 With Windows Server 2012, it’s been replaced by a suite of PowerShell cmdlets contained in the ADDSDeployment module.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…

  I frequently need to display the disk size, available disk space properties and Processor details of my remote Hyper-v 2012 Hosts servers. I could use the Computer Management snapin to do this, but it involves too many steps just to get there. The Get-VM cmdlet while cool, will not display disk based properties. So I…
