Create File NCP May Not Function Correctly with Read and Write Access Flags (242193)

  • Microsoft Windows 98 Second Edition

SYMPTOMS

When you create a file on a Novell NetWare server with read and write permissions, a handle to a file opened with read-only permissions may be returned. Subsequent attempts to use this handle in a write operation are unsuccessful.

CAUSE

This behavior occurs when the Microsoft Client for NetWare Networks (Nwredir) is installed. The Client for NetWare Networks code that handles the File Create NCP command (0x2222 87 01) attempts to open the file with the correct read and write permissions. If the call is unsuccessful, the original create request flags are checked for OPEN_ALWAYS. If the file is not opened with OPEN_ALWAYS, the process continues to the next check to see if the error status equals 0x90 (Some Files Read Only). If the ACCESS_READWRITE bits are set, the process toggles off the WRITE bit and attempts to open the file with ACCESS_READONLY. If this call is successful, the read-only handle is returned to the caller.
