Posted on 7th May 2021 by Rhoderick Milne [MSFT]

The days change, but sometimes the issues stay the same. This is a redux of an existing post where there was an issue back in 2016 when I was not able to easily re-create a VM in a different Availability Set. As you can see in Create Azure RM VM Using Existing VHD – 250 Hello (rmilne.ca) PowerShell was used to re-create the VM as it allowed all of the resources to be specified.

Posted on 26th April 2021 by Rhoderick Milne [MSFT]

The below is from a customer situation where an Azure Network Security Group (NSG) firewall rule entry was not working as they expected. This was was created to allow RDP connectivity for some of their test servers.

One of my hosted lab environments ran into series of issues, and after unplanned maintenance there were multiple problems to resolve.

Since the feature is enabled by default and is self-managing, there is a good chance that you are benefiting from it without being fully aware of it.

Posted on 6th April 2021 by Rhoderick Milne [MSFT]

The default option for DNS resolution on an Azure virtual network is to use the Azure DNS service. This is perfectly fine for regular Internet requests, if you need the capability to register internal DNS records for Active Directory then you will typically need to run your own DNS service. This is the case here and is also something observed with multiple customers. In each of these cases the … Read the rest “Intermittent Azure DNS Resolution Issues With With New Domain Controller”

QuickTip – Removing IE11 Via Command Line

Posted on 26th March 2021 by Rhoderick Milne [MSFT]

Now that multiple services have stopped supporting IE11 coupled with the end of support for legacy Edge, it is imperative that we transition to an updated browser on all of our devices.

QuickTip – Which Managed Availability Components Are Unhealthy?

Posted on 28th September 2020 by Rhoderick Milne [MSFT]

Exchange 2013 introduced the Managed Availability feature, so Exchange can self monitor and perform recovery actions upon itself. While this has greatly helped Exchange become more self-healing, one of the downsides is that there is no real UI for Managed Availability. The only UI is the Managed Availability Event Logs. All of the configuration inside of Exchange is done using PowerShell. The … Read the rest “QuickTip – Which Managed Availability Components Are Unhealthy?”
