Solarwinds - Error: "Network connection failed. HResult: No

By -
During our Exchange 2010 upgrade project we noticed the monitoring on one server stopped working.

We use a product called Solarwinds, this uses a combination of Powershell, WMI and SNMP to monitor services on hardware and software from around the business.

We noticed that Solarwinds would return the following error message when polling this particular server

Network connection failed. HResult: No data to return. Error: Unable to connect to the specified computer, or the computer is offline.

After a quick search online we found the following Solarwinds KB

It recommends restarting the WMI service on the server. We completed this but the issue remained.

One of my learned colleagues kept searching and found that the Remote Regsitry service was set to Manual. He set it to Automatic and started the server.

Immediately the polling began to work!

So if you have this problem, check the Remote Registry service!

Cheers to John Manley for finding this!

Introduction Starting with Windows 10, version 1703, Windows 10 Pro supports the Subscription Activation feature, enabling users to “step-up” from Windows 10 Pro to Windows 10 Enterprise automatically if they are subscribed to Windows 10 Enterprise E3 or E5. The Subscription Activation feature eliminates the need to manually deploy Windows 10 Enterprise or Education images on each target device, then later standing up on-prem key management services such as KMS or MAK based activation, entering GVLKs, and subsequently rebooting client devices. It’s important to note that the Windows 10 Enterprise subscription activation is designed to “step-up” a device from Windows 10 Pro to Windows 10 Enterprise. Therefore, your device is required to have a Windows 10 Pro license activated as a baseline. For Windows 10 Enterprise Subscription Activation to function, there a several prerequisites which need to be in place. This blog is aimed for organisations which have Active Directory on premises an...

Power Automate: Get first item in output

By -

One of the most annoying things about Power Automate for me is when I am trying to use the output of a previous action and as soon as I click that dynamic content button, it pops my new action into a For Each loop. It does this because the previous action could have more than 1 item returned and this would clearly fail unless it was in a loop. But if you have used the Row Count or Top option in the proceeding action, or you know full well that only 1 item will return, it is nice to avoid bloating the flow with an unnecessary loop. There are a couple of way to do this: First function You can craft your filter expression so that the output is wrapped in the First function. This will tell Power Automate to only look at the first item. First(variables('Array')) Calling Index You can edit your filter expression to tell it which item from the source you want. Zero being the first item e.g. variables('Array')[0] Which one to use? I use the index and the main reason is due to...

De-selectable radio buttons - Power Apps

By -

Introduction When creating a Canvas Power App you can choose from a large number of controls and specifically input controls designed to get information from the user. One of these controls is the humble radio button. This is a good control which provides possible options without requiring a user action. In comparison a dropdown would require the user to click to expand all of the possible options. Example radio button input One of problems with this control is the fact you cannot de-select it. Once an option has been chosen, you can change it but you cannot undo it. The post shows a way to make de-selecting possible in a Canvas Power App. One simple way to achieve this is to have a button or icon next to the radio button and its OnSelect property to be Reset(rdoButton). This is easy, but if there are many radio button controls, it could result in lots more controls on a screen or in an app. Power Apps recommends keeping under 500 for an app and 300 maximum per page. The followi...
