KB4494440 Known problems

Here are some common problems that are described below.

Problem #1

SCVMM (System Center Virtual Machine Manager) cannot list or manage hosts’ local switches individually. If you do not follow best practices, a stop error may occur in the vfpext.sys files of hosts.

You can solve this error message by considering these two useful methods.

  1. Run mofcomp on the following mof files on the assigned host:
    Scvmmswitch.mof port settings
    VMMDHCPSvr.mof
  2. Follow the procedures above to bypass a stop error in vfpext.sys in an SDN v2 environment.

Problem #2

After installing KB4467684, an error message “2245 (NERR_PasswordTooShort)” may appear, preventing cluster services from failing. This error only occurs when the Minimum Password Length group policy is set to 14 characters or more.

To solve this problem, you must enter 14 characters or less as the minimum password length and then set it as the default domain.

Problem #3

After installing the KB4494440 cumulative update, some actions, such as renaming files or folders, may fail and display the following error code.

“STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”

This only happens if you perform such actions on a clustered shared volume, for example, CSV. This can also happen if you do not use administrator rights to perform such functions on a CSV proprietary node.

To solve this problem, try one of these two solutions.

  1. Log in as an administrator to perform a similar operation.
  2. Complete the process from a node that does not require CSV owner rights.
