Answer 1

Hi,

Thanks for posting on our forum!

Based on your description, firstly, I have checked the error message "An error occurred while executing the test. Object reference not set to an instance of an object." And it turns out that this is a NullReferenceException error and may be related with your .NET framework feature. In .NET, you can divide data types in two categories: value types and reference types. If you have a variable of a value type, it stores the value itself. Reference types variables, on the other hand, don’t hold the value itself. They hold a reference that points to where the object lives in memory. So, when you try to call a method or another member which contains nothing, you got the NullReferenceException. In this place, just check if you have enabled .NET framework feature in your Server Manager properly.

Secondly, I noticed that you also have your network communication "Warning", I wonder if you could open this report and tell me what is the description for being "Warning". We need to firstly check if you have some improper configuration for network communication, like there are any NICs on the same node that are configured to be on the same subnet. Then, if your configuration works fine, then the issue may be caused by NIC itself, like your NIC is not suitable for cluster network. If so, you need to query your vendor.

Finally, if none of them above suits your situation, I would suggest you contact Microsoft Customer Support and Services where more in-depth investigation can be done so that you would get a more satisfying explanation and solution to this issue. In addition, if the issue has been proved as system flaw, the consulting fee would be refund. You may find phone number for your region accordingly from the link below.

Answer 2

Hi Jayaozhu,

Thank you for the reply.

I am configuring cluster for two virtual nodes on Hyper-V Host.

.Net Frame work is already installed & i dont see any issue with .Net frame work.

Network communication is showing as success after adding heart beat IP address for both the nodes. However, "List Network Metric Order" still shows as failed.
I have attached the error message. Kindly let me know if any other details are required.

Hi,

Thanks for your reply!

Based on the results of your troubleshooting, now we can basically be sure that your problem comes from the network card itself. The solution was not that simple to find. The underlying virtual machine template may have an error on the network card. So every time you try to reinstall it, the error is already build in.

In this case, I will strongly suggest you to seek help directly from your vendor and if your network card is our Microsoft product, then you can open a case with our senior engineers from Microsoft Customer Support and Services. They can conduct more in-depth investigation for you and try to fix your network card issue. In addition, if the issue has been proved as system flaw, the consulting fee would be refund. You may find phone number for your region accordingly from the link below.
