So I downloaded a bunch of files from "the way back machine" site and I needed to update the hard-coded links to be relative site links. The following little script did it for me.
Adding DNS records to Windows DNS - For CPTR 446 class
SCVMM Powershell scripts
I needed this once when I was trying to refresh the Library share. It failed on refresh with an error saying that a DVD was in use and wouldn't refresh until it was no longer in use. The following commands allowed me to identify the machines.
In general all of these need:
1 Import-Module VirtualMachineManager
Get a list of Virtual Machines that have a DVD attached
List VMs at the end of the semester to be deleted
1 Get-SCVirtualMachine | Select Name, MarkedAsTemplate, Owner | Sort-Object -Property Owner, Name | Export-Csv -Path .\vms2019w.csv
Get a list of VM Mac Addresses for CPTR 427
1 Get-SCVirtualMachine | Where-Object { $_.Name -like "*427*" } | select -ExpandProperty VirtualNetworkAdapters | select MacAddress
Setting up a Windows 2019 Server for the first time
1 # Install the AVMA key.
2 slmgr /ipk TNK62-RXVTB-4P47B-2D623-4GF74
3
4 # Set the timezone
5 # First I'm going to search for the timezone I want
6 Get-TimeZone -ListAvailable | Where-Object {$_.DisplayName -like '*Eastern*'}
7 # This gave me the parameter needed to set the time zone.
8 Set-TimeZone -Name "Eastern Standard Time"
9
10 # Set the Hostname of the computer:
11 Rename-Computer -NewName "windows2019" -Restart
12
13 # Next we need to install Windows update and get it started.
14 # This will install nuget package too.
15 Install-Module PSWindowsUpdate
16
17 # Now start the update process
18 # First we'll look at what updates are there
19 Get-WUInstall
20 # Now install them
21 Install-WindowsUpdate
Power shell to list of VM hard drives sizes
List the amount of memory used by virtual machines
