Data loss has occurred
You upgraded your operating system or switched from one Windows SKU to another SKU, and data from the previous installation of IIS has been lost or copied incorrectly. As a result, the services W3SVC and MSFTPSVC have been disabled. Before enabling these services, you should review the latest IIS 7.0 compatibility information.
