Windows 10 Preview – VMs Missing In Hyper-V Manager

Posted on 16th October 2014 by Rhoderick Milne [MSFT]

After updating my Windows 8.1 machine to the Windows 10 preview, some of my VMs were no longer visible in the Hyper-V Manager. Prior to powering on some VMs, all of them were visible. After powering on, some VMs disappeared in the Hyper-V Manager console.

In the screen shot below, there should be 10 VMs displayed which have the prefix of “HA”.

How To Check Exchange Autodiscover SRV Record Using Nslookup

Posted on 2nd October 2014 by Rhoderick Milne [MSFT]

Generally the Exchange external Autodiscover DNS entity is configured as a regular A record. Sometimes a service record (SRV) is used instead. Since I have the habit of forgetting the syntax of quickly querying for the SRV record, this is one of those shared bookmark posts!

Nslookup is the tool of choice here! Its documentation can be found on TechNet.

There are two ways to run nslookup – interac… Read the rest “How To Check Exchange Autodiscover SRV Record Using Nslookup”

Sharing the Registry Editor Favourites Love

Posted on 5th September 2014 by Rhoderick Milne [MSFT]

In the previous post on the topic of the Registry Editor’s favourites menu, Andrew Higginbotham was kind enough to point out that there was also an easy way to export the favourites from one machine and import to another. Since its always good to show how to arrive at a solution, let’s breakdown the process of finding out where this data is squirreled.

As always we can use the venerable Sysinternals… Read the rest “Sharing the Registry Editor Favourites Love”

Posted on 2nd September 2014 by Rhoderick Milne [MSFT]

A virtual machine from Windows Server 2012 R2 cannot be directly imported into Windows Server 2012. This is discussed in this previous post along with the import error 32784 .

There will be times when we want to take a 2012 R2 VM and import it into 2012, this happened to me recently when setting up one of the workshops that I deliver to customers. While the setup guide said to deploy 2012 … Read the rest “Importing Server 2012 R2 Hyper-V VM Into Server 2012”

Hyper-V Did Not Find Virtual Machines to Import – Error 32784

Posted on 29th August 2014 by Rhoderick Milne [MSFT]

When importing a VM into Windows Server 2012 that was exported from Windows 2012 R2 you will be unable to import the VM. If you import the VM using PowerShell’s Import-VM cmdlet the error message is not very descriptive – “The operation cannot be performed because the object is not in a valid state”. You will also find EventID 15040 in the VMMS event log.

PowerShell Input Output Escapades

Posted on 13th August 2014 by Rhoderick Milne [MSFT]

After using various types, architectures and generations of computers over the years there is always the habit of “you go to what you know!” In other words once you figure out a solution to an issue, you then use that repeatedly in the future as you know the process/steps involved. This adroitly describes me when it comes to doing certain command line tasks. If I were being a bit… Read the rest “PowerShell Input Output Escapades”

Quick Tip – Event Viewer Filtering

Posted on 6th August 2014 by Rhoderick Milne [MSFT]

I was recently reminded of a simple yet effective Event Viewer filtering tip. If you have thousands of event entries that are pollution/flooding the log it becomes very difficult to see the actual real issues.

For example this tip has proved very useful when the application event log is full of these types of noise:

EventID 1 from MSExchange Autodiscover stating Unhandled Ex

Retrieving Packets Received Discarded Perfmon Counter From Multiple Servers

Posted on 18th July 2014 by Rhoderick Milne [MSFT]

Whilst working on a customer’s Exchange 2010 DAG issue, I wrote a quick script to quickly grab some performance monitor counters from all of their Exchange servers. The issue that we were investigating was related to discarded packets when the VM was running on a certain hypervisor host. The customer had moved their Exchange VMs to a new host and after doing so they were experiencing cluster iss… Read the rest “Retrieving Packets Received Discarded Perfmon Counter From Multiple Servers”

Outlook 2013 Distorted Display Issues

Posted on 8th July 2014 by Rhoderick Milne [MSFT]

After a recent video driver update, my corporate Outlook client started to do some strange things. Within Office 2013, the screen output would be distorted. Menu bars were not painted properly until I mouse-over them again, or moved Office programs around. Other times the display would look corrupted and the navigation tree would not be properly rendered.

Exchange and AntiVirus Exclusions – Still A Critical Conversation

Posted on 30th June 2014 by Rhoderick Milne [MSFT]

In a previous post we saw the Microsoft requirements for the exclusions that must be added to file system AV on Exchange servers. In a recent CritSit, basically an uber urgent support request where the customer is down or as good as down, I also got to examine some of the other causes for file system AV not being correctly configured for Exchange.

In the aforementioned post the majority of the… Read the rest “Exchange and AntiVirus Exclusions – Still A Critical Conversation”
