Classic ASP runs as an optional IIS feature. Deploy it only on a Windows release under Microsoft support and install the ASP role service explicitly.
| Environment | Guidance |
|---|---|
| Windows Server | Use a supported LTSC release and install Web Server (IIS) → Application Development → ASP. |
| Windows client | Use optional IIS features for local development, not as a production-server substitute. |
| Containers or VMs | Use a supported Windows image and document IIS and COM dependencies. |
| PWS and old IIS | Do not use on internet-facing systems. |
dism /online /enable-feature /featurename:IIS-WebServerRole /all
dism /online /enable-feature /featurename:IIS-ASP /allConfirm feature names for the exact Windows image. See Microsoft’s ASP configuration reference and Windows Server 2025 lifecycle.
