The error pops when you start the trace: Unable to start trace, the required event providers were not found. Contact your system administrator.

Cause: Some how you dont have Dynamics in event viewer

Resolution: execute the script below under C:\Temp in powershell

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26  $AOSSetupETWManifestDir = "K:\AosService\WebRoot\Monitoring" foreach ($manifestFile in Get-ChildItem -Path $AOSSetupETWManifestDir\*.man | select-object -Property BaseName,Name) {$dllFile="" if ((Test-Path "$AOSSetupETWManifestDir\$($manifestFile.BaseName).Instrumentation.dll")) {$dllFile = "$AOSSetupETWManifestDir\$($manifestFile.BaseName).Instrumentation.dll" } elseif ((Test-Path "$AOSSetupETWManifestDir\$($manifestFile.BaseName)Resource.dll")) { $dllFile = "$AOSSetupETWManifestDir\$($manifestFile.BaseName)Resource.dll" } elseif ((Test-Path "$AOSSetupETWManifestDir\$($manifestFile.BaseName).dll")) {$dllFile = "$AOSSetupETWManifestDir\$($manifestFile.BaseName).dll" } else { Write-Host "Warn : Skipping$AOSSetupETWManifestDir\$($manifestFile.Name) as DLL not found" Continue } Write-Host "Installing $AOSSetupETWManifestDir\$($manifestFile.Name) using$dllFile" wevtutil.exe im "$AOSSetupETWManifestDir\$($manifestFile.Name)" /rf:"$dllFile" /mf:"$dllFile" Write-Host "Finished installing$AOSSetupETWManifestDir\$($manifestFile.Name) nn" } 

Then restart the VM by LCS or Azure portal, you will get the Dynamics back in the event viewer and able to start the trace normally.
