There are different Stratum levels which apply to servers and devices, which distinguishes them from each other. Taken from this article, the following gives a brief rundown on the different levels. Stratum 0 These are devices such as atomic clocks,…

Logon to the vSphere client > Inventory > Configuration > Networking > You will most likely have one Virtual Switch already configured. The aim here is to add Jumbo Frames to a new VMkernel Port by adding a new VMkernel port with Jumbo Frames. As your VMkernel port would have IP addresses attached to it for the management network (your connection to the host), you will need to create a brand new Virtual Switch first that has no VMkernel port added to it. Call this vSwitch1. You will need to do these next steps from the Command Line Interface on…

Once the box is manually ticked in Active Directory, admin users should be able to connect as normal to their mailboxes. But you need…

Preferred Networks and Metrics In Hyper-V, when you enable Cluster Shared Volumes, the failover cluster automatically chooses the network that appears to be the best for CSV communication. However, you can designate the network by using the cluster network property, Metric. The lowest Metric value designates the network for CSV and internal cluster communication. The second lowest value designates the network for live migration, if live migration is used (you can also designate the network for live migration by using the failover cluster snap-in). Another property, called AutoMetric, uses true and false values to track whether Metric is being controlled…

The following will exclude servers from SCCM automatic discovery only, this exclusion registry entry does not apply to the Client Push Installation Wizard. This is the client push installation log file located on the SCCM site server: %ProgramFiles(x86)%\Microsoft Configuration Manager\Logs\ccm.log When checking this log file, you might notice constant attempts to install the SCCM agent on machines that are not needed to be included in your SCCM environment, for example network appliances.
