This SMB is used to verify that a path exists and is a directory. No error is returned if the given path exists and the client has read access to it. Client machines which maintain a concept of a "working directory" will find this useful to verify the validity of a "change working directory" command. Note that the servers do NOT have a concept of working directory for a particular client. The client must always supply full pathnames relative to the Tid in the SMB header.
