I’m working a challenge where the cluster validation tool on a Server 2008 R2 SP1 based cluster throws an error running the unsigned driver inventory/validation. It doesn’t say that there are any unsigned drivers but rather says:
An error occurred while executing the test.
There was an error getting information about the unsigned drivers installed on the nodes.
There was an error retrieving information about the Unsigned Drivers from node 'someclusternode.contoso.com'.
Shutting down
If we run the tool from other nodes it will always pass itself and 4 out of the 5 other nodes, but there will be one node that will trigger this. And the node that it fails on is not consistent.
All of the other tests run just fine, and I can’t find anything in any KB that points me in a troubleshooting direction.
