• Demoting the last Windows Server 2012 R2 Domain Controller with PowerShell.

  As with promoting a server to domain controller, demoting the a domain controller is also a straight forward process with PowerShell. The following PowerShell cmdlets are available from the ADDSDeployment module: Uninstall Active Directory: The demote process got a little tricky because this was the last DC in the domain and had an Operations Master…

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 With Windows Server 2012, it’s been replaced by a suite of PowerShell cmdlets contained in the ADDSDeployment module.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

• Converting a User Mailbox to Resource Room Mailbox using PowerShell.

  In past versions of Exchange Server, specifically Exchange 2003, managing Resource Room mailboxes was not exactly a straight forward process. In my organization at the time, to manage room Calendars and bookings for Conference rooms (they were not referred to as Resource Rooms at the time), we had to create mailboxes to represent the conference…

• Checking Available Disk Space and Memory with Powershell.

  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…

• Configuring multiple ISCSI Connections for Multipath IO using PowerShell.

  This post will be focused mainly on the ISCSI Initiator host and configuring multipath IO paths to an ISCSI Target. The ISCSI Target portal has already been configured with 2 network paths for ISCSI. The ISCSI Service by default is in a ‘Stopped’ state.

• Configuring Hyper-v Host Network Adapters for ISCSI Storage Connectivity with Powershell .

  Windows Server 2012 R2 with PowerShell 4.0 has hugely expanded support for configuring multiple NICs on a Cluster/ISCSI Initiator node via command line. After deploying multiple Network Interface Cards on my Hyper-v host, it took me a while to figure out how to properly configure the NICS with PowerShell . Prior to Windows Server 2012,…
