Hi. We're getting error with event it 6237 (source FailoverClustering-WMIProvider) on a 2008 R2 SP1 Hyper-V cluster.
There was an older thread http://social.technet.microsoft.com/Forums/en-US/bae84aea-5a80-4637-989b-c31bbc1aa55a/event-id-6237-failover-cluster-wmi-provider-detected-an-invalid-character?forum=windowsserver2008r2highavailability which suggest installing KB974930, but that update is not applicable on my nodes (probably part of SP1?).
How do we solve this issue?
My message is concerning different property (PreviousOfflineAction - which I failed to find using either GUI, PSH or cluster.exe):
Failover Cluster WMI Provider detected an invalid character. The private property name 'PreviousOfflineAction' had an invalid character but the provider failed to change it to a valid property name. Property names must start with A-Z or a-z, and valid characters for WMI property names are A-Z, a-z, 0-9, and '_'.
