I have been exploring a bit with both Azure and Azurestack and when you onboard your VM´s to Log Analytics and the security center you soon get noticed about 100s of drilions attempts to log on to your mashine if you have made it available through RDP. Although there now is a way to take care of this in a better way using the Security Center JIT Access giving a timespan for opening the port and also limiting to certain IP/networks! Some times an JIT access is not what you can live with but an alternative port could be utilized then the following can be applied.
A recent update to the Azure portal have now surfaced where you get the option to dowload the RDP file with an alternative port instead of the standard 3389, that does not
set the NSG to allow for the new port
set the VM´s internal RDP service to respond to it
So to get the possibility to connect to the virtual machine we need to update the NSG and also reconfigure the virtual machine to actually listen on the new rdp port
First I add a row on the NSG
and then i utilize the custom script extension and change the listener on the virtual machine for RDP
New-NetFirewallRule-DisplayName'Allow RDP in Custom Port'-Profile@('Domain','Private','Public')-DirectionInbound-ActionAllow-ProtocolTCP-LocalPort@($NewPort)
If I am utilizing an AzureStack all above can be achieved but in the portal the connect button will be greyed out so you can still connect to it but you need to manually enter the public IP and custom port:
There is a new (re-released) course on the openedx.microsoft.com site where you can sign up and start learn about Azure Stack and also from the 30th of March do labs to enhance the learning experience!

Short “how-to” videos for viewing each task should you get stuck and need to see how it’s done
As I described earlier I had an eval image in my marketplace that I used to provision servers and I wanted some of them to be converted so they could be correctly activated and reconfigured away from eval.
The AzureStack uses the function within Hyper-V for the VM´s that is called Automatic Virtual Machine Activation and as you can see in the device manager the device Microsoft Hyper-V Activation Component and the VM´s should have the appropriate AVMA key on them and if the host is licensed with the right key the VM will activate automatically.
On this page you can find the keys you need for the different guest-OS that it can be used with! A Windows Server 2016 AVMA host can activate guests that run the Datacenter, Standard or Essentials editions of Windows Server 2016 and Windows Server 2012 R2.
Utilizing the DISM command I can check what license I had and then use DISM /online /Set-Edition:ServerDatacenter /ProductKey:xxxxxx-xxxx-xxxx-xxx-xxxx /AcceptEula
If you just want to change a key and not versions you can utilize the slmgr /ipk <AVMA_key> instead of the DISM!
So now we have come to some interesting parts in my experience with our multinode Stack, In this post I will go through Marketplace management and installation of App Service RP.
To actually get something into the marketplace for tenants we need to either populate it ourselves with custom images or utilize the marketplace syndication. After deploy of the stack you need to register it to Azure.And when you have successfully done that you will get possibiltiy to download azure images that have been made available.
In the powershell tools you can find the command to upload a custom image that you might want to make available for your tenants, there is though no way to make them just available for one tenant. I utilized the superfunction Convert-WindowsImage and created a new insider Windows Server 17093 for my tenants marketplace.
then using the Azurestack tools you upload it with Add-AzsVMImage
Important: You as a Stack Admin will be responsible to make sure that the latest Images have been updated on your Marketplace, there is no automation magic that will download a new Windows Server Image once it has been released in Azure and thus keeping your marketplace up to date for tenants and they can deploy without having to patch and patch and patch before they utilize their systems…
Looking at one example my SQL VM that I have downloaded from Azure was version 14.1000 and now there is a new that I need to update to:
App Service RP
Installation of the SQL RP was very much straight forward and just follow the instructions and run (there is though one thing and that is regarding the above marketplace, you will need a Windows Server Core available for the SQL RP)
for the App Service there is a bit of more work and the prerequisite says a file server :” For production deployments, the file server must be configured to be highly available and capable of handling failures.” and a SQL server: “For production and high-availability purposes, you should use a full version of SQL Server 2014 SP2 or later, enable mixed-mode authentication, and deploy in a highly available configuration.“. Luckily You can run these in default subscription and not in a tenant subscription… But still there are some serious life cycle management that needs to be handled here with patch and update, security etc on these 6 servers (AD, FS, SQL)
After when You have those prerequisites in place it is time to start the App Service wizard, and there we had the first encounter of problems.. I had the superduper SSL cert with everything including SANs or so I thought……
Coming back to my second post you should verify a thousand and thousand times with the certificate department at your company that they do not try to take any shortcuts and miss any critical SANs. In our case an assumption that a wildcard was enough to take this rocket out of orbit for a couple of hours and getting a bit more grey hair! So make sure you have a SAN name in your certificate that says sso.appservice.<region>.<xx>.domain.yy and you will not get “The certificate dns is invalid: azurestack”
Next thing that we encountered which showed a bit later was that we deployed using the eval image (this was not to obvious in the wizard, as we had both a eval and a regular in our syndicated marketplace)
And as you can see in the Wizard during app deploy it does say latest 2016 Datacenter and nothing about eval!
Now Microsoft and the Azure team have removed the Eval from the Syndication so if you do not create your own custom image with Eval you will not get into this problems and need to mitigate this..
Once the Win 2016 Eval was removed we could get a ordinary version up on the workers by scaling their scale sets down and up, but we had to fix the controllers manually.
Also make sure that you do not lock down the SQL and fileservers vnet and public IP´s with a too narrow NSG and not let app workers and controllers reach smb shares and sql services or your app service will die and not respond!
Now we have come to my fourth post on my series of AzureStack multinode experince, previously I have been writing on the importance on the network and certificates for a successful deployment.
This post will describe the success path with updates to be applied and keeping us compliant with the support cycle, you can only be up to 3 updates behind or you will be left without support!
When we got our stack it was deployed with 1709 and during the installation process the OEM-engineers that where onsite added 1710 and 1711. When the 1712 came out we did the update ourselves. Based on our learnings it is good to have ms support standby so start with a support case because to have a more successful run of the update pack you will want to check status and space on the infrastructure VM´s and it is only in a broken glass support session connected to the privileged endpoint on a ERCS node you can get help and verify the state! Probably in future update packs they will address issues and thus making it more stable and resilient and you then will not be needing a support call but better be safe than sorry!
First as the documentation describes, upload the update files to the storage account called “updateadminaccount” where you would add a container (private) with the update:
When all the files are uploaded you can go into the update and start. When highlighting the patch the “update now” link above lights up and you can press it to start the update process!
The whole process takes about 8-12 hours depending on the size of the update and how many nodes you have in your Stack!
We had one hotfix that needed to be applied after the update of 1712 and the learning from that was that the apply failed and failed and failed but not giving a good explain on why but we learned that was because we did not RTFM and uploaded the whole folders content and not just the xml,exe and bin but also a Supplemental Notice.txt (in our defence, the update packs does not contain the text file), so removing that one and then the retry succeeded without any issues!
We have some users on-boarded on the AzureStack multi-node system and they do testing and when they forget to remove stuff and we need to make some changes we might need to remove their resources and as Stanislav mentioned there is a way to actually take over a subscription. There is though a small thing that needs to be added to the PowerShell cmds that can change a Azure Stack user subscription owner when you have a multitennant setup of your Stack, your users will have their own tenant ID´s on the subscriptions.
So to be able to access and remove resources from an user that left his subscription and resources burning you will have to do a update on both Owner and TenantId
So set up your enviroment with the AzureStack tools and PowerShell environment, connect as a cloud operator to the default subscription and then run the following::
# Get all User subs
# save the user subscription you want to take over into variable
Here is my second post on experience with our lovely AzureStack multinode that we now have running.
First of all, there is now a good doc on the AzureStack site for Datacenter Integration and it is really important to read and understand the text. It is also vital to also have the networking guys on the wagon!
For a success in the deployment you will need to have a NAT functionality within your router/fw or have a transparent proxy. The doc says it is needed for the Infra Network that is called public, it is not public reachable but do need internet access. Some routers have advanced functionality with Policy based routing that can send infra traffic to a fw and public VIP traffic directly to and from internet!
Also during deployment the BMC network will need access to internet because the deployment VM running on the HLH will need to do a AAD login and registration if the stack is not being deployed as a disconnected version.
Before you can get a deployment up and running you will need to make sure that the certificates that you ordered are rock solid! Follow the documentation and do not take any short cuts in wild card certs etc…
There is a sample cert INF template file that you can use:
I know that I have been more than usual quiet in my blogging the latest months, that is because we have had much at work and I have been over my head in new tech stuff and among that I also been the lead in the implementation of our AzureStack multinode.
I will do a couple of blog posts about my experience and caveats that I have stumbled on so keep checking back!
First of all Me self and Geir-Morten from our company will do a session on friday at the NIC conference in Oslo
The Three Amigos fighting compliance with Azure Stack
Hybrid cloud with Azure Stack can deliver great benefits to your organization, helping you innovate and get faster to market. But at the same time also protect your sensitive information and stay compliant with regulations like GDPR. This session will focus on the different roles associated with the Azure Stack, from operating the Stack to the developer and IT pro bringing their solution into a true hybrid environment. The sessions will be packed with demos on a Azure Stack multi-node system showing the different roles in action in environment spanning not only Azure and Azure Stack, but also private clouds.
After installing/deploying the AzureStack DevKit i added the SQL RP and also wanted to add the App Service Resource Provider for a dev experience!
I have an relative ordinary HPE 380 G9 box with 128 GB of ram and 2 CPU´s so it should be fine, but there was some issues that I wanted to document to help others, this will probably be fixed in an later release of the App Service install pack though.
I downloaded the bits and ran the deploy App Service
After filling this out the deployment started but after a few hours it failed during the deploy step, I tried the Retry a couple of times but without luck, also closing the wizard makes you lose the stage of deploy and need to rerun the whole deploy! When doing a redeploy you have to delete the resource group APPSERVICE-LOCAL (or what you called it) and also go into your SQL server that you entered into the wizard and remove the appservice db´s!!
How did I mange to get it working though? I got some help from Andrew at Microsoft that works with the Stack team and he gave me some guidance how to get it into a good state! Apparently the App Service adds all uppdates during deploy and to be more successful the recommendation was to update with patches that was released up until last tuesday with the win2016 image and thus update to latest CU, mine came from the marketplace syndication with Azure and that one had not the patches when I did this test, I threw that away and ran the create image script adding the parameter for -includeLatestCU.
Rerunning the wizard and when it allthough had a image with latest and greatest patches got stuck on “App Service Deploy Failed” I went into the CN0-VM and opened the mmc for the state of the different servers in the App Service
I also hit the repair link and when all of them said “Ready” I added a new 0.status file I got from Andrew into the custom script folder on the CN0-VM, easiest way to do that was with the lovely PowerShell Direct that is part of the Win 2016!
and then went back into the wizard hitting Retry and this time it continued to the finish and my deployment was successful!
