[keschnei42]

When Start-DSCEAscan is run against either a large (100+) server text file or using a -path containing (100+) servers mof files the following error is often displayed as some of the servers LCM are in use:

WARNING: Cannot invoke the Test-DscConfiguration cmdlet. The Consistency Check or Pull cmdlet is in progress and must return before Test-DscConfiguration can be
invoked. Use -Force option if that is available to cancel the current operation.
WARNING: Cannot validate argument on parameter 'Id'. The argument is null. Provide a valid value for the argument, and then try running the command again.
