Azure Digital Twins Public Preview Release - Authentication

-
There are latest updates and news coming out from the Public Preview channels and one of them is related to the Azure Digital Twins. Azure Digital Twins now supports both system-assigned and user-assigned managed identities for authenticating to supported endpoints for routing digital twin events. Azure Digital Twins already supported system-assigned identities, but now with this public preview release you have even more flexibility with user-assigned managed identities. A common challenge for developers is the management of secrets, credentials, certificates, and keys used to secure communication between services. Managed identities eliminate the need for developers to manage credentials that are used to authenticate endpoints supported by Azure Digital Twins. You can use either of these managed identity types to authenticate to these endpoints.  Detailed information and configuration of Managed Identity can be reviewed over here High-Level Overview of Managed Identities for A

Windows 2019 Server Change TimeZone error "Unable to continue" You Do not have permissions to perform this task.

 Namaste everyone, During the install of a new Azure AD Connect software I was provided a brand new Windows 2019 Server Datacenter Edition and this was fully patched and updated with the Security patches. There were no Group Policies with exception of the Domain Policy and a SCCM Server Policy for patching. I noticed the time was out of sync an hour as the server was located in the different region and all other servers were set to local region settings. So the usual step is to try and change the date and time from the Control Panel, however when I tried to update the time I received a message that I cannot change the time. "Unable to continue" You Do not have permissions to perform this task. Please contact your administrator for help. The simple fix to use the Get-Timezone and Set-Timezone PowerShell commands,  Get-TimeZone -ListAvailable | where StandardName -like "*GM*"    ( This command will extract the specific Timezone with the words GM in the StandardName, y

Azure Active Directory Connect Upgrade In-place or Swing Migration

-
In this article we are going to discuss different methods that you can use to upgrade your Azure Active Directory (Azure AD) Connect installation to the latest release. I have been reading lot of queries and question mark over the type of upgrade process or approach should be taken by the Architects or an Engineer managing the AAD Connect software. First of all, it is very important that the environment and specially the servers  are in line with the current and the latest releases of Azure AD Connect. Microsoft is constantly making upgrades to AADConnect, and these upgrades include fixes to security issues and bugs, as well as serviceability, performance, and scalability improvements. As been on the field working for different clients the issues and confusion is whether to do in place upgrade or do a swing migration, Microsoft states with small environment and not many complex settings usually in-place upragde should be carried out. But in my opinion I do not like to disturb the e

Windows 11 22H2 RDP disconnects and freezes randomly

-

Namaste Everyone. I have been following and reading many forums with the similar issue of RDP session freezing or either getting disconnected frequently. Logs have not proved anything exceptional or drastic changes in the environment, however I was able to test this in my lab and have traced some Network Logs via the Wireshark and could see retransmision packets between the client and the server. This all started after the update to Windows 11 22H2. The resolution is to either rollback the 22H2 on the client or apply this registry or ADMX setting via the Group Policy. My theory is that after looking at the logs in my client is that the problem is due to the fact that the RDS connection is trying to connect over UDP and is not trying to connect over TCP if the UDP fails or gets block for some reason. So either you can manually set the registry in the client by following the below step: Browse to the below Registry Path with administrator account: HKLM\SOFTWARE\Policies\Microsoft\Windows

So back in end of March 2022, Microsoft released a news that they are coming with a Specialist Certification in Azure that will assist and help Support Engineer's.

Updating User Principal Name On-Premises for Azure AD Connect

-
Hello Folks Namaste,  Another nugget for updating the UPN for the users, if you are setting up AAD between the on-premise AD and Azure AD you will need to follow the guide to add the custom domain name in AD. Also in addition to that we will need to update the user's UPN by following the below powershell script. In my scenario I had to update the .local UPN Suffix to .com UPN suffix for all the users in the environment. Note: Just test this in a test or dev environment before running on the production environment. Open up ISE or Powershell in a admin mode: $LocalUsers = Get-ADUser -Filter "UserPrincipalName -like '*pacman.local'" -Properties userPrincipalName -ResultSetSize $null $LocalUsers | foreach {$newUpn = $_.UserPrincipalName.Replace("@pacman.local","@pacman.com"); $_ | Set-ADUser -UserPrincipalName $newUpn} Hope this helps if you are trying to update or modify the User's UPN. Cheers, Jimmy
