WDSMCS_E_INCOMPATIBLE_VERSION

WDSMCS_E_INCOMPATIBLE_VERSION is a Windows Deployment Services (WDS) Multicast Server result. It indicates that the provider and WDS Multicast Server do not agree on a supported content-provider interface version.

What to check

  • Verify the provider version, Windows Server version, and SDK or header version used to build the DLL.
  • Deploy a provider compiled for the same WDS multicast interface generation as the target server.
  • Record the version negotiation values in provider diagnostics before replacing binaries.
