Windows Patch Notes for CTE v7.5.0

Resolved Issues

• AGT-51298 [CS1528438]: After CTE agent is installed, Microsoft Cluster Shared Volumes changes to redirect access state when using the VMLFS driver

  The issue only occurred when the user switched to the VMLFS driver. The solution is to:

  1. Uninstall/install/upgrade CTE on all cluster nodes, without rebooting.

  2. Reboot the nodes successively. Wait for each node boot up before rebooting the next node.

• AGT-54979 [CS1537336]: Unexpected Windows Server Reboot

  The issue occurred because the code was changed to support higher IRQLs for writes for a performance gain, but missed a path that tried to perform a function that is not allowed at a higher IRQL. This has been fixed.

Known Issues

• AGT-36370: The vorvmd.log reports an error message when guarding LDT over CIFS GuardPoint

  CTE agent needs CIFS credentials to apply a GuardPoint on a CIFS share. This error message displays when CTE agent is in the process of authenticate the user. This error can be safely ignored.

• AGT-39189: CTE failed to unguard after changing to incorrect CIFS credentials

  If a user has a CIFS guarded path, and tries to access it with invalid credentials, the unguard request fails. After this, if the user switches to valid credentials, the unguard request still fails.

  Work-around

  To successfully guard/unguard a CIFS path, use valid credentials.

• AGT-48196: Microsoft DPM reports recovery creation failed when creating a recovery point after synchronizing data

  Work-around

  Perform a complete backup. Do not perform an incremental backup. The incremental backup does not work properly with LDT.

• AGT-48580: RWP: gzip files in a directory can be mistakenly identified as ransomware

  Intermittently, zip or unzip activity that occurs within a ransomware GuardPoint is identified as ransomware.

  Work-around

  Add the zip/gzip/winzip programs to the Ransomware Protection process exemption list in the CipherTrust Manager client profile.
