WDSMCS_E_NAMESPACE_ALREADY_STARTED
WDSMCS_E_NAMESPACE_ALREADY_STARTED is a Windows Deployment Services (WDS) Multicast Server result. It indicates that the requested start operation was issued for a namespace already in its active transmission state.
What to check
- Read the namespace state before starting it and treat an active equivalent state as success where appropriate.
- Prevent duplicate start requests from retry logic, concurrent workers, or management automation.
- Use the existing transmission state and client list rather than recreating the namespace.
