WSAESTALE - Error 10070

Question/Problem: Stale NFS file handle.

Answer/Solution: An attempt was made to access an open file on an NFS (Network File System) which is now unavailable as referenced by the file descriptor. This may indicate the file was deleted on the NFS server or some other catastrophic event occurred.

NFS is "network-related" in the strictest sense, but the NFS protocol is an application protocol (that is, a "high-level" protocol). The Windows Sockets API provides access to "low-level" APIs (like the transport protocols TCP and UDP), so this error is not relevant to Winsock.
