Getting a lot of these on my SQL Server cluster (SQL 2008 on Windows 2008), mostly on the inactive nodes. I have Googled a bit and found nothing really helpful.
Access to the root\mscluster namespace was denied because the namespace is
marked with RequiresEncryption but the script or application attempted to
connect to this namespace with an authentication level below Pkt_Privacy.
Change the authentication level to Pkt_Privacy and run the script or
application again.

Error Microsoft-Windows-WMI
Error code: 5605
Eventlog: Application
Note: I did lock down security about this time on these Servers, making the SQL Server Service Account (MYDOMAIN\SQLAcct) not an admin on the box anymore but giving it proper local security policies to run the cluster per Pro SQL Server 2008 Failover Clustering (Apress) by Allan Hirt (see chapter 5 "Service Accounts, Domain Groups, and Rights" p.186).
Local Security Policy SQL Server
Adjust memory quotas for a process
(SeIncreaseQuotaPrivilege) Yes
Bypass traverse checking
(SeChangeNotifyPrivilege) Yes
Log on as a batch job (SeBatchLogonRight) Yes
Log on as a service (SeServiceLogonRight) Yes
Replace a process-level token
(SeAssignPrimaryTokenPrivilege) Yes
My first instinct is to make MYDOMAIN\SQLAcct an admin again and see if these go away… rule that out or in, at least. But this won't really solve the problem since I don't want my service account to be an admin on the box.
Thanks.
