Deleting Files on Samba Servers May Delete Local Files Instead

Q140558

The information in this article applies to:

Microsoft Windows 95

SYMPTOMS

When you use the Microsoft Client for Microsoft Networks (Vredir.vxd) to connect to a Samba file server running on a UNIX-based computer and you try to delete files on the server, you may delete files on your Windows 95-based computer instead.

CAUSE

This behavior occurs because Samba file servers let you create file names with characters that are invalid in Windows 95. These invalid characters include the following characters:

backslash (\)
asterisk (*)
question mark (?)

For example, Samba file servers let you create file names such as c:\*.* or \\server\share\*.*. If a UNIX user creates a file called "c:\*.*" and shares it, a Windows 95 user who connects to the server and tries to delete the file with Windows Explorer or My Computer may delete all the files in the root directory of local drive C instead.

NOTE: You are not affected by this problem if any of the following conditions are true:

You are not connected to a local area network.
You do not use a dial-up application (such as Dial-Up Networking) to dial into a local area network.
You are connected to a local area network, but you do not connect to Samba file servers running on UNIX-based computers.
You connect to Samba file servers running on UNIX-based computers but you delete only files you created with Windows Explorer or My Computer.

RESOLUTION

Although this is not a problem with Windows 95, Microsoft has released a new version of the Vredir.vxd file (version 4.00.955) that filters out files that have file names with invalid characters. When you use the updated version of the Vredir.vxd file, you cannot see these files and cannot, therefore, try to delete them.
