#### Solution

1. Log in to the ECS. The following operations use an ECS running Windows Server 2012 R2 as an example.
2. Click Server Manager in the lower left corner.
3. Choose Tools > Internet Information Services (IIS) Manager, expand Sites, and select the target website.
4. Click Basic Settings to check whether the Physical path is correct.
5. The correct physical path is that of the mount point with the colon (:) deleted.
