Live Migrating a Virtual Machine from a Hyper-v 2012 stand-alone Host to WS2012 R2 Cluster and Configuring Kerberos Constrained Delegation..

After multiple attempts, I have come to the conclusion that directly moving a Virtual Machine from a Hyper-v 2012 stand-alone host to a Windows Server 2012 R2 cluster is not exactly a feasible option right now. I’ve been able to achieve this by a two step process. a) Move the target VM to a ‘staging’…

Configuring Network Adapter TCP/IP Settings using Powershell 4.0 Cmdlets .

PowerShell 4.0 is a requirement for these cmdlets to work.The GUI( Graphic User Interface) is commonly used to configure network adapter settings or the good old netsh command. But if I had to work with Hyper-v core or Windows Server 2012 R2 core, there’s a number of PowerShell cmdlets that could be used in place…

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…
