Windows Server fails to install optional component
Microsoft (DISM) Wednesday, 06 July 2022 by paul

When trying to add a Windows Server optional component it fails. Checking the DISM log shows the error message “DISM Package Manager processed the command line but failed. HRESULT=800F0954”

 

This can be resolved by enabling the policy “Specify settings for optional component installation and component repair” and ticking the option “Download repair content and optional features directly from Windows Update instead of Windows Server Update Services (WSUS)”.

Graphical user interface, text, application, email

This can be done locally on the server (using gpedit.msc) or by a centralised group policy. The policy is under “Computer Configuration\Policies\Administrative Templates\System”.

After amending then gpupdate the server and try installing the component again.

Check Team Creation restricted to security group
Office 365 (Teams) Tuesday, 14 June 2022 by paul

To check if Microsoft Team creation is restricted to a security group run the following PowerShell:

# Uninstall Azure AD module
Uninstall-Module AzureAD
# Install the latest AzureADPreview module
Install-Module AzureADPreview
Connect-AzureAD
$settingsObjectID = (Get-AzureADDirectorySetting | Where-object -Property Displayname -Value "Group.Unified" -EQ).id
$groupSettings = (Get-AzureADDirectorySetting -Id $settingsObjectID)
$groupSettings.Values

In the output check if the value EnableGroupCreation is set to false. This will restrict Team creation to a security group. The value GroupCreationAllowedGroupId specifies which security group has access to create Teams.
