The Double-Hop Problem - Knowledgecast. Understanding Kerberos Double Hop - Ask the Directory Services Team. Hi, Steve here.
Kerberos Double Hop is a term used to describe our method of maintaining the client's Kerberos authentication credentials over two or more connections. In this fashion we can retain the user’s credentials and act on behalf of the user in further connections to other servers. Naming Files, Paths, and Namespaces. All file systems supported by Windows use the concept of files and directories to access data stored on a disk or device.
Windows developers working with the Windows APIs for file and device I/O should understand the various rules, conventions, and limitations of names for files and directories. Data can be accessed from disks, devices, and network shares using file I/O APIs. Files and directories, along with namespaces, are part of the concept of a path, which is a string representation of where to get the data regardless if it's from a disk or a device or a network connection for a specific operation.
