Centralized private resolver architecture implementation using Azure private DNS resolver
This article walks you through the steps to setup a centralized architecture to resolve DNS names, including private DNS zones across your Azure network and on-premises DNS using an Azure DNS private Resolver in a hub and spoke VNet topology.
Architecture diagram:
In the above architecture:
Two VNets are created: “HUB-VNET” and “SPOKE-VNET”.
An Azure DNS private resolver is created in the HUB-VNET with inbound endpoint at (10.0.0.4)
A DNS forwarding ruleset is created for the private resolver “myruleset”.
The DNS forwarding ruleset is linked to the HUB-VNET.
Rules are added to the DNS forwarding ruleset for the on-premises DNS server.
HUB-VNET is linked to all the Azure private DNS zones with Virtual network link.
On-premises network is simulated as a third VNet and is peered to the HUB-VNET.
ExpressRoute, Azure Firewall and ExpressRoute gateway are representational. On-prem to Azure connectivity could be a mix & match of ExpressRoute and Site-to-Site.
A conditional forwarder is created in the on-premises DNS server for the private DNS zones configured on Azure to inbound endpoint at (10.0.0.4).
Create Azure Hub virtual network:
Create HUB-VNET with address space 10.0.0.0/24 and two subnets.
Subnet name: snet-inbound
Subnet address range: 10.0.0.0/28
Subnet name: snet-outbound
Subnet address range: 10.0.0.16/28
Create a DNS resolver inside the Azure HUB virtual network:
Create DNS private resolver in “HUB-VNET” with a DNS forwarding ruleset “myruleset”
DNS forwarding ruleset “myruleset” is created and linked to the HUB-VNET during the DNS private resolver creation. In this example there is only one rule in the ruleset.
Rule Name: onprem-contosocom
Domain name: contoso.com
Destination IP: port: 192.168.0.4:53 (On-premises DNS server)
Add a Virtual network link for HUB-VNET with Azure private DNS “privatelink.blob.core.windows.net”
Create Azure spoke virtual network:
Create SPOKE-VNET with address space 10.0.1.0/24 and one subnet.
Subnet name: app-subnet
Subnet address range: 10.0.1.0/26
Create a peering connection between SPOKE-VNET and HUB-VNET.
Specify the inbound endpoint IP address of the DNS private resolver (10.0.0.4) as the custom DNS server for SPOKE-VNET.
Create a conditional forwarder:
On-premise DNS server conditional forwarder
DNS Domain: blob.core.windows.net
Forwarder: 10.0.0.4
Test the DNS resolution
Now you should be able to send resolve DNS from Azure to on-premise as well as on-premise to Azure.
DNS resolution On-Premises:
On-premise client query’s on-premise DNS server (192.168.0.4).
On-premise DNS name is resolved by the on-prem DNS server
For Azure private DNS conditional forwarder is used. On-premise DNS server forwards the DNS request to Azure private DNS resolver inbound endpoint (10.0.0.4).
Azure private DNS resolver uses the outbound endpoint to query Azure DNS (168.63.129.16) and resolves the DNS query for “myblobdnsdemo.blob.core.windows.net.” to (192.168.2.78)
DNS resolution in the hub VNet:
The virtual network link from the private zone to the Hub VNet enables resources inside the hub VNet to automatically resolve DNS records in privatelink.blob.core.windows.net using Azure-provided DNS (168.63.129.16).
Based on the ruleset “myruleset”, DNS resolution for contoso.com is forwarded and resolved through on-premise DNS server (192.168.0.4).
All the namespaces which are not matching the ruleset rule are resolved without forwarding using Azure-provided DNS. E.g. public DNS names.
DNS resolution in the spoke VNet:
The spoke VNet uses custom DNS and sends all of its DNS traffic to the inbound endpoint in the Hub VNet.
Since “privatelink.blob.core.windows.net” has a virtual network link to the Hub VNet, all resources in the Hub can resolve “privatelink.blob.core.windows.net”, including the inbound endpoint (10.0.0.4). So, the spoke uses the hub inbound to resolve the private zone.
Contoso.com DNS names is resolved for the spoke VNet through (192.168.0.4) according to rules provisioned in a forwarding ruleset.
Conclusion: Azure private DNS resolver helps implement a private resolver architecture without worrying about maintaining your own DNS server.
One can implement a centralized private resolver architecture as shown above example or can implement a distributed DNS architecture. In case of a distributed DNS architecture, the DNS forwarding ruleset is linked to the spoke VNet with a ruleset rule configured to forward queries for the private zone to the inbound endpoint (10.0.0.4) of the private DNS resolver deployed in the hub VNet and another rule to forward queries for contoso.com to on-premise DNS server (192.168.0.4)
DNS resolution in the hub VNet does not require a ruleset for private zones as it can resolve privatelink.blob.core.windows.net using Azure-provided DNS (168.63.129.16). It requires a ruleset to forward queries for contoso.com as shown in the above example “myruleset” rule “onprem-contosocom”.
Important: Hub VNet linked ruleset must not be linked to a forwarder ruleset with an inbound endpoint forwarding rule because this configuration can cause a DNS resolution loop.

Import mesh from Matlab to Ansys with additional properties of each element
I have obtained a finite element mesh of an image using im2mesh file by JieXian Ma. I want to export it to Ansys, but I need not to just export a mesh (it’s already implemented in this file), but first I have to assign Modulus of Elasticity value to each of the node.
From the image I have I’ve also obtained color intensity matrix (in grayscale). I multiplied it by Elasticity Modulus I have (it represents the non-homogeneity of a bone) and then I need to somehow assign this matrix’s values to the mesh.
Mesh consists of verticies (n-by-2) (x and y coordinates) and triangles (m-by-3) (numbers of verticies building up a triangle) vectors. The matrix is a square one.
Also I consider removing zeros from the matrix, as it’s not needed in the mesh creation, but then it transforms into a long vector, longer than previous ones and I don’t know how to do it normally.
So, maybe someone knows how to assign values to the mesh?
Below are the images of the mesh, bone image and vectors and a color matrix I have.I have obtained a finite element mesh of an image using im2mesh file by JieXian Ma.

Problem with 3D Meshgrid – Not understanding why some planes are 0 which results in my dx becoming 0
Hello,
For context: Trying to make a Navier Stokes solver in Matlab, starting with 1D just to see if it will work.
To start I am using the meshgrid do discretize the spatial domain into grids. This is done with the following code:
L = 1 % Length of the cube side
n = 100 % Num of gridpoints
x = linspace(0, L, n);
y = linspace(0, L, n);
z = linspace(0, L, n);
[X, Y, Z] = meshgrid(x,y,z);
Now this works and I get three 100x100x100 matrices for X, Y and Z. The problem Im having is understanding how it actually works in generating each individual element. I understand that it reallocates the points in a grid formation from the input values, which is how I want it. However when testing it with this code:
for t=1:T
for i = 2:n-1
for j = 2:n-1

U_new(i) = U(i) + dt*(u_convection + u_diffiusion);

The dx terms result in 0 for all the iterations. At this point im just trying for 1D just to make sure it works so dont mind the nested loops, those are for later usage.
From what I can see the X matrix has alot of concecutive values, like X(1,88,56) through to X(99,88,56) all have the value 0.8788. Thus it is logical that dx results in 0.
Could somone please explain why we have the same values in the same "vector" of X, as I dont really understand the documentation of gridmesh(). Also if anybody has any ideas to make the dx term work that would be appriacated as well.
Thanks in advance!Hello,
For context: Trying to make a Navier Stokes solver in Matlab, starting with 1D just to see if it will work.
To start I am using the meshgrid do discretize the spatial domain into grids. This is done with the following code:
L = 1 % Length of the cube side
n = 100 % Num of gridpoints
x = linspace(0, L, n);
y = linspace(0, L, n);
z = linspace(0, L, n);
[X, Y, Z] = meshgrid(x,y,z);
Now this works and I get three 100x100x100 matrices for X, Y and Z. The problem Im having is understanding how it actually works in generating each individual element. I understand that it reallocates the points in a grid formation from the input values, which is how I want it. However when testing it with this code:
for t=1:T
for i = 2:n-1
for j = 2:n-1
for k = 2:n-1
dx = X(i+1,j,k) – X(i,j,k);
dy = Y(i+1,j,k) – Y(i,j,k);
dz = Z(i+1,j,k) – Z(i,j,k);
if dx <= 1e-10
continue;
else
disp(dx)
end
end
end

Forecasting decay rate – preventing negative values
Hi,
I am developing a series of forecasts for health care services using historical per capita rates as the source data. In some areas, there has been a rapid decline in use. When this is forecast using a standard linear regression model the values quickly become negative. Given that these are unrealistic results (you can’t have negative health care services), I have capped the values at zero.
In this instance, there will always be some usage. What is a sensible way to determine a floor value that is greater than zero?
Here is a chart to illustrate.

Filtering for specific rows and concatenating cells within that row
I have made some headway on this one, but falling short. I need to filter for rows with a specific cell value. Then once found, return a specific cell and concatenate a group of other cells in that row. What I have working is only an attempt at the filter and concatenation but my formula is concatenating all rows with the specific cell value “BUNDLE IDENTIFIER”. I think if I had a unique value , I could reduce the scope. I know there has to be a better way.

Outlook is attempting to authenticate to the Exchange server using local username and password
Hi!
We are using Exchange Server 2016 with the latest updates and primarily using Outlook 2019 or 2021 clients. We have bound an internal Exchange mailbox account, and every time Outlook is launched on a non-domain computer, it attempts multiple authentications on the Exchange server using the local user account (some of my users are working on non-domain computers). However, Outlook actually functions properly. I’m not sure why it is attempting to authenticate using the local username. I have checked if the incorrect username and password are saved in the Credential Manager for the user. I can see a large number of Event 4625 audit failures in the failed logs on the Exchange server,
corresponding to my non-domain computer account “ZYY” in this case.

Conflicting Applications: Other software or background processes running on the system may conflict with QuickBooks, causing it to freeze. This can happen due to incompatible software versions or conflicting system configurations.
Solution For QuickBooks Keeps Freezing After QuickBooks Update:
1. Optimize Company File:
Regularly perform file maintenance tasks within QuickBooks to optimize the company file’s performance. This includes condensing data, removing unused list entries, and running the Clean Up Company Data utility to reduce file size and improve efficiency.
2. Increase System Resources:
Upgrade your system’s hardware components, such as adding more RAM or upgrading to a faster SSD, to provide QuickBooks with the necessary resources for smooth operation. Additionally, close unnecessary applications and background processes to free up system resources.
3. Update QuickBooks:
Ensure that you are using the latest version of QuickBooks and have installed all available updates and patches. Intuit releases updates regularly to address bugs, enhance performance, and improve compatibility with various systems.
4. Verify Data Integrity:
Regularly run the Verify and Rebuild Data utilities within QuickBooks to check for and repair any data integrity issues within the company file. This can help prevent freezes caused by corrupted or damaged data.
5. Check for Software Conflicts:
Identify and uninstall any third-party applications or utilities that may be conflicting with QuickBooks. Pay attention to recently installed software or updates that coincide with the onset of freezing issues. Once conflicting applications are removed, test QuickBooks to see if the freezes persist.
6. Adjust Compatibility Settings:
If QuickBooks is experiencing compatibility issues with the operating system, try adjusting compatibility settings. Right-click on the QuickBooks shortcut, select Properties, go to the Compatibility tab, and experiment with different compatibility modes or settings.
7. Reinstall QuickBooks:
As a last resort, consider uninstalling and reinstalling QuickBooks to ensure a clean installation free from any corrupted files or settings. Before reinstalling, make sure to back up your company file and any important data to prevent loss.
Conclusion:
Dealing with QuickBooks freezes can be frustrating, but with the right approach, you can minimize disruptions and ensure smooth operation of the software. By addressing potential causes such as large company files, insufficient system resources, corrupted program files, outdated software or drivers, and conflicting applications, you can mitigate freezes and optimize performance. Remember to stay proactive by regularly optimizing your company file, upgrading system resources as needed, keeping QuickBooks updated, and troubleshooting software conflicts to prevent future issues.

New problem adding mailboxes with personalized domain to Outlook with Microsoft 365 Family ?
Hi all
Having a big problem with this recently and need your help to understand if Microsoft has made a general change with Office 365 Family accounts with personalized domains, or if it is just my individual problem.
I’ve been running Outlook on my PC with a Office 365 Family account and personalized / custom domain @NotMyRealDomain.EMAIL using namesilo.com for DNS for 1.5 years.
Everything worked fine, although in my online (outlook.live.com) web-based mailbox under Settings->Premium–>Personalized Email Address, it has always said “We couldn’t connect the domain NotMyRealDomain.EMAIL to Outlook. Cancel setup and try again.” But as I said everything worked so I didn’t mess with this. (Now if I press “cancel setup” it warns me that this will disconnect my personalized domain and I wont be able to restore it due to MS discontinuing support for personalized domains in the Office Family plan. So I’m definitely not pressing that button.)
The problem is that my Outlook profile is corrupted (I think) and to debug the problem I need to create a new profile. But I cant.
When I try to create a new profile, it fails to add my mailbox using Autodiscover. I enter my email address RON@NotMyRealDomain.EMAIL and my password, it tries to setup outlook and eventually fails. Manual setup also fails. In some cases it complains the username RON@NotMyRealDomain.EMAIL is incorrect, in other cases it says it cannot contact the server. At the same time, I have no problems using this email address using the web-client.
This worked 3-4 months ago, and nothing changed except I updated my version of Office.
So I suspect that Microsoft changed something with how Outlook recognizes and/or configures mailboxes.
Can somebody who runs outlooks with a Family 365 account with a personalized domain (ideally not on godaddy) please try to create a new additional profile to see if you have the same issue?
If it works OK for you and if you are not running the latest version of Outlook (Outlook for Microsoft 365 Version 2404 Build 16.0.17531.20128 MSO 64-bit, the latest Current Channel version) can you try updating your Office to see if that causes the problem?
If indeed MS changed something it could be bad news…
thanks for your help!
