DSC resource pull issues.

dan-potter · July 24, 2017, 1:35pm

Resource pull suddenly stopped working. The following is logged in eventvwr. The module is present at C:\Program Files\WindowsPowerShell\DscService\Modules\xPSDesiredStateConfiguration_6.4.0.0.zip.

Job {2676CBEB-70A1-11E7-8147-005056A61D85} :

I’ve restarted the server, iis to no avail.

The zip file is present at that location or the module?

Is this using Pull Server or the Azure service?

So, first you need to check and make sure that the folder containing the ZIP is what the Pull Server is configured to use as its Resource path. Also ensure a valid checksum file exists.

The error message you showed is obviously from the client; it’d be nice to start a trace and see if the server itself throws anything.

A restart rarely accomplished anything when it comes to the pull server, so I wouldn’t waste time on more of those ;).

A concern is that the LCM isn’t logging the module name, though. That makes me suspect a problem on the node, where, again, restarting the server wouldn’t have had any effect. A more detailed log - e.g., Debug or Diagnostics, not Operational - might indicate something more. Based solely on what you’ve posted, I don’t even see the LCM attempting to pull the module.

It might be worth deleting any local copy of the module that the node already has, and seeing what it does.

DSC pull server.

The module is zipped as xPSDesiredStateConfiguration_6.4.0.0.zip in \Program Files\WindowsPowerShell\DscService\Modules\

couple of additional things you can do:

Check the Meta configuration settings for ResourceModuleManagers and see if server is reachable by other means (invoke-WebRequest).
On client side, DSC will always go through module discovery and download as necessary and along the way would write events to ETW channel mainly as verbose messages, look for them for any useful information.

Use xDscDiagnostics module

GitHub - dsccommunity/xDscDiagnostics: This module contains cmdlets for analyzing DSC event logs.

to troubleshoot or share the logs.

The diagnostics don’t seem to offer any more information than the event log unless I’m doing it wrong. I’m baffled, it was working and nothing changed.

Events on all clients.
