EVT_WDSMCS_E_NON_WDS_DUPLICATE_MULTICAST_ADDR
EVT_WDSMCS_E_NON_WDS_DUPLICATE_MULTICAST_ADDR is a Windows Deployment Services (WDS) Multicast Server result. It indicates that the requested WDS multicast address conflicts with another multicast service on the network.
What to check for EVT_WDSMCS_E_NON_WDS_DUPLICATE_MULTICAST_ADDR
- Identify the host or application using the address before changing WDS configuration.
- Choose an unused multicast address or range approved for the deployment network.
- Coordinate with network operators when multicast traffic crosses routed or shared segments.

Diagnostic interpretation
This result has the HRESULT value 0xC1210203. AllStat records the condition as “The multicast IP address %1 is being used by another multicast server, which has IP %2. Use the Windows Deployment Services management tools to configure your multicast IP address range to avoid this multicast IP address. If you allow this overlap to continue, your network usage will be increased.”.
Evidence to capture
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the evt / wdsmcs / non / wds / duplicate operation.
- Preserve the first failure in the call chain; a later HRESULT can describe cleanup rather than the original evt / wdsmcs / non / wds / duplicate condition.
Retry and recovery
Retry this result only when the owning API documents a transient state or after the condition described as “The multicast IP address %1 is being used by another multicast server, which has IP %2. ” has changed.
