Cause (Documented platform behavior): HNS uses ICS to create the NAT virtual network for WSL 2; without it the network cannot be created. Fix status: documented_behavior Limitations: - Doc-derived; not reproduced. Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/MicrosoftDocs/WSL/7ea1c6f9e25f1c89a05a0e97e5325a02a66ac6cd/WSL/troubleshooting.md (official_docs, unknown, documented_behavior): 'WSL 2 errors when ICS is disabled': ICS is required by HNS for WSL 2 NAT/DNS/DHCP; disabling SharedAccess breaks WSL 2 creation and v1→v2 conversion with 'There are no more endpoints available from the endpoint mapper.' Search phrasings: WSL There are no more endpoints available from the endpoint mapper; wsl --set-version 2 endpoint mapper; WSL2 SharedAccess service disabled Evidence basis (self-declared by the contributing chat client): public_source.
