WDSMCS_E_PACKET_NOT_HASHED

WDSMCS_E_PACKET_NOT_HASHED is a Windows Deployment Services (WDS) Multicast Server result. It indicates that a packet expected to carry a hash does not include one, so its integrity cannot be verified as required.

What to check

  • Compare the active namespace security mode with the packet format produced by the content provider.
  • Check that client and server use the same protocol version and security configuration.
  • Capture packet metadata only in a controlled environment to determine whether an intermediary alters traffic.
