Cannot resize Azure VM due to Accelerated Networking being enabled

 You decide to drop the size of a D series Azure VM to B series and are told it's incompatible with Accelerated Networking, perhaps you don't care.

Here's how to disable Accelerated Networking, no reboot required!

In Azure Portal, find the relevant info for your VMs 'network interface name' and 'resource group name', use those in place of the <placeholders> and run the command in Azure CLI from the icon in the top-right of the portal. 

Your VM will continue to run and will not drop the network connection. Once the command has completed you can resize your VM.

az network nic update --accelerated-networking false --name <network interface name> --resource-group <resource group name>

Outlook Room Finder does not load data/work

The error message: We can't open the Room Finder right now. Please try again later.

For Room Finder to load data in Outlook 'Edge Webview2' is required to be installed, this appears not to happen on RDS Session hosts.

Webview2 can be installed on a user-by-user basis or for all users if installed by a local admin. The Evergreen edition is recommended in most cases.

Start menu stops working in Windows Server 2019 & 2022

 You find that the Start button does nothing when left-clicked, you still get the Win+X menu when right-clicking.

This article has a great writeup. I have found the solution does work, although users will see a delay when logging off.

If you are fully patched add the following reg key.

Add “DeleteUserAppContainersOnLogoff” (DWORD) in “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy” and set it to 1. 

It's worth reading the whole article linked above as it explains the issue better and there is a script which can help with removing extra firewall rules that contribute to the issue.

Non RDS, RDP Certificate Install

To get rid of the yellow untrusted warning when connecting to RDP. 

1, Install the cert via MMC.

2, In PowerShell run the following.

Get-Childitem Cert:\LocalMachine\My

 

3, Copy the Thumbprint and run the following replacing the word 'Thumbprint' without spaces or extra character at the beginning.

wmic /namespace:\\root\CIMV2\TerminalServices PATH Win32_TSGeneralSetting Set SSLCertificateSHA1Hash="Thumbprint"

Cannot replace TLS/SSL Certificate on Microsoft Dynamics BC or NAV

If you get the following error when setting a new thumbprint on a BC/NAV instance:

SSL Certificate add failed, Error: 183 Cannot create a file when that file already exists

The answer is to note down the port number in the error then use it with this command to remove the existing certificate mapping. (replace 443 with the port from the error message.)

netsh http delete sslcert ipport=0.0.0.0:443

You can now set and save the new thumbprint in your instance configuration.

List installed certificates and their thumbprints in PowerShell

Enter the following to list installed certificates and their thumbprints in PowerShell

Find install dates of apps in Windows from CMD

Clearing a stuck RDS session, session stuck logging off etc

On the session host, first I run query session to get a list of session IDs.

Then run query process /ID:XX where XX is the session ID number to find processes running in the session.

Then go to task manager and click the details tab look up the PID (process ID) and 'end task' on each process in the stuck session until it logs off.

Using PowerShell to find when domain users last set their password

 A simple one, enter the following into PowerShell running as a domain admin to export a list of domain users with the date they last set a password and if their password is set to expire.

Get-ADUser -filter * -properties passwordlastset, passwordneverexpires | sort-object name | select-object Name, passwordlastset, passwordneverexpires | Export-csv -path c:\PassLastSet.csv

You can of course also use CMD. Which is much simpler and easy to remember.

Move Outlook Navigation Toolbar Back to Bottom From Side

 In a recent update of Office 365 applications the Outlook toolbar that switches between email, calendar and contacts was moved from the bottom-left to the top-left of the main window.

Here's how to move it back.

1. Open regedit
   
   
2. Go to the following registry key
   Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentEcs\Overrides
   
   If you have the ‘Microsoft.Office.Outlook.Hub.HubBar’ string value and set it to ‘false’.
   Then click OK and restart Outlook.
   
   If  “Microsoft.Office.Outlook.Hub.HubBar” doesn’t exist, create it by right-clicking on Overrides in the left pane and selecting New, String Value then name it “Microsoft.Office.Outlook.Hub.HubBar”
   Set the value to 'false'
   
   
3. Close and restart Outlook

Restoring an Azure VM to earlier disk state from backups (unmanaged disks)

Restore the disks from backup and use Storage Browser in the Azure Portal to place them where you want them, please note they will restore to the root of your Storage Account.

Open Cloud Shell in the Azure Portal and use the following commands to set variables, read the VM configuration, and update the VM configuration with the new OS disk location. 

# Variables for you to fill in

$ResourceGroup = 'RG-Classic'

$VMname = 'winclassic'

#Get the VM config to a variable

$VM = Get-AzVM –Name $VMname –ResourceGroupName $ResourceGroup

#Stop and deallocate the VM

Stop-AzVM –Name $VM.Name –ResourceGroupName $VM.ResourceGroupName –Force

#Swap out the OS disk using the VM variable

$VM.StorageProfile.OsDisk.Vhd.Uri = 'https://rgunmanageddisknew.blob.core.windows.net/vhds/rhclassic-os-2317.vhd' #example, use your new OS disk uri

#Update the VM configuration

Update-AzVM –VM $VM –ResourceGroupName $ResourceGroup

You can now verify the disk location has changed by clicking on the disk in the VM/Disks section and looking at the location.

Data disks can be swapped out within the Azure Portal GUI.
