MicrosoftNot sure if this will help anyone else, I still have an ongoing case with Microsoft regarding the "Parameter is incorrect error" They have advied that all 3rd party filter drivers can possibly produce the error at logon.
Below is an output of the driver filters on one of our VPC's and the possible conflicts (Crowdstrike, CPM, Symantec DLP, Appsense & AppDisk)
We went along some testing and removed all of these drivers one by one, each time the error was produced until we finally removed CrowdStrike AV. Once all the drivers were gone the error no longer occurred, after many many logons (50+). Reinstalled CrowdStrike and the error occurred on the very 1st logon.
We do have the recommended AV exclusions in-place.
Continuing to work through with MS & CS.
