  • Hyper-V Replica and VMs Failover with PowerShell

    Hyper-V Replica offers a convenient and efficient way to provide failover capabilities for Hyper-V VMs, especially outside of a Hyper-V cluster.

Among other benefits, it can also […]

I will use the Silverlight setup as an example in this article. This can be applied to any EXE setup file. We will start […]

    When we were in the process of migrating our SCCM 2007 hierarchy to the newly installed SCCM 2012, we encountered around 150 revoked clients that were being denied registration.
