"Access Denied" Attempting to Run File on LM/X Server

Q157114



The information in this article applies to:


  • Microsoft Windows 95





SYMPTOMS

When you are using a Windows 95-based computer to connect to a LAN Manager for Unix (LM/X) server, you may receive an "Access denied" error message when you try to run a file that has only Read and Execute permissions.



CAUSE

When a Windows 95-based computer connects to a server using the SMB (Server Message Block) protocol for file and print sharing, it negotiates a dialect level for the connection. Some LM/X servers support only older dialect levels.

When an older dialect is negotiated (the Microsoft Networks 3.0 dialect in this case, also known as Core SMB), the Windows 95 client must use only those SMB commands supported by the down-level server. In this case, the Windows 95 client issues an "open" SMB command, requesting open mode 23 or execute mode. However, the "open" command supports only read, write, and read/write mode, making it an illegal SMB command.
