ConfigMgr OSD taking hours to complete due to LEDBAT misconfiguration

Hi All

I recently had a customer report that their Windows 10 deployment was taking 7+ hours to complete at one of their remote sites. After confirming that the machine was pulling content from it’s local Distribution Point, I started looking at the server itself, which is running Windows Server 2016.

The customer mentioned to me that they had enabled LEDBAT on this Distribution Point via the ConfigMgr console, and had then disabled it after hearing reports of OSD issues at this site.

I came across this article which stated that a misconfiguration of LEDBAT could cause slow download speeds when pulling content from a Distribution Point, so I decided to double check that this wasn’t the case. Instead I found that there were still traces of incorrect LEDBAT configuration on this server even though it had been disabled via the ConfigMgr console.

LEDBAT - ConfigMgr OSD taking hours to complete due to LEDBAT misconfiguration

LEDBAT misconfiguration

After running the following PowerShell command to remove this configuration, and then confirming it no longer existed, build times returned to normal!

Remove-NetTransportFilter -SettingName DatacenterCustom

Note that the Primary Site server has the latest 1806 update rollup installed which has fixes for LEDBAT configuration issues, however I am not sure if it was installed after LEDBAT had been enabled on this Distribution Point.

So if you hear that deployments are taking a long time to complete, check that LEDBAT misconfiguration isn’t causing the problem!

Hope this helps!

Unable to open Microsoft Edge in Windows 10

I had an issue for a customer this week where Microsoft Edge had suddenly disappeared from their machine.

Running the Get-AppxPackage PowerShell cmdlet confirmed that the universal application was still installed on the machine:

Get-AppxPackage | where Name -like *MicrosoftEdge*

msedge 1 - Unable to open Microsoft Edge in Windows 10

So Microsoft Edge was still on the machine and fortunately PowerShell came to the rescue.

Get-AppXPackage -AllUsers -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml" -Verbose}

msedge 2 1024x249 - Unable to open Microsoft Edge in Windows 10

This successfully reinstalled Microsoft Edge and restored it’s functionality!

Cheers
