When you install (Subsystem for UNIX-based Applications) and NFS (Network File System) on Windows Server 2003 R2 that is running IIS (Internet Information Services), the System event log records:
Event Type: Error
Event Source: SUA
Event Category: None
Event ID: 1013
Computer: <Computer Name>
Description: Could not connect to Mapping Server at host localhost:while connecting : RPC: Success
This behavior will occur if SUA is configured to start Automatically.
To workaround this behavior:
1. Start / Run / Serices.msc / OK.
2. Double-click the SUA Subsystem Startup service.
3. Toggle the Startup type to Manual.
4. Press Apply and OK.
