How do I resolve "Cannot invoke the SendConfigurationApply method." when performing Start-DscConfiguration?
I've found the following works pretty well to reset DSC. Note this will delete the local configuration, so you will need to re-apply the machinename.meta.mof file.
#Remove all mof files (pending,current,backup,MetaConfig.mof,caches,etc)rm C:\windows\system32\Configuration\*.mof*#Kill the LCM/DSC processesgps wmi* | ? {$_.modules.ModuleName -like "*DSC*"} | stop-process -forceAt this point you have a clean system ready to be configured using Set-DscLocalConfigurationManager and updated using Update-DscConfiguration -Wait -Verbose -CimSession machinename
So far the only thing this hasn't fixed is a corrupted $env:psmodulepath or missing scheduled tasks for Consistency/Reboot checks. Update: According to this item on connect the scheduled tasks for Consistency/Reboot were removed in the WMF 5.0 February preview.
You could also try executing the start-dscconfiguration command with the -Force option
Start-DscConfiguration -Force ...
