    After installing KB5009610 or any updates released January 11, 2022 and later on your domain controllers, scenarios which rely on Read-only domain controllers (RODCs) or synthetic RODC machine accounts might fail to establish a Netlogon secure channel. RODC accounts must have a linked and compliant KRBTGT account to successfully establish a secure channel. Affected applications or network appliances, such as Riverbed SteelHead WAN Optimizers, might have issues joining domains or limitations after joining a domain.

    Next Steps: Affected apps and network appliances will need an update from their developer or manufacturer to resolve this issue. Microsoft and Riverbed are presently investigating and will provide an update when more information is available.

    Affected platforms:

    • ​Server: Windows Server 2022; Windows Server 2019; Windows Server 2016; Windows Server 2012 R2; Windows Server 2012; Windows Server 2008 R2 SP1; Windows Server 2008 SP2

    Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege.

    Affected platforms:

    • ​Client: Windows 8.1; Windows 7 SP1
    • ​Server: Windows Server 2012 R2; Windows Server 2012; Windows Server 2008 R2 SP1; Windows Server 2008 SP2

    Workaround: Do one of the following:

    • ​Perform the operation from a process that has administrator privilege.
    • ​Perform the operation from a node that doesn’t have CSV ownership.

    Next steps: Microsoft is working on a resolution and will provide an update in an upcoming release.
