FTP GET Does Not Work Correctly on UNC Virtual Directories

ID: Q237987

The information in this article applies to:

Microsoft Internet Information Server version 4.0

SYMPTOMS

When you map a virtual directory to a UNC path and allow Anonymous Access, you may be able to PUT a file to the FTP site, but the GET command fails.

CAUSE

When handling a PUT, FTP uses the credentials configured in the virtual directory configuration dialog. The GET command uses the credentials of the logged on user. The result is that you can send and delete the file to or on the FTP server, but cannot get it back.

RESOLUTION

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Windows NT service pack that contains this fix.

   4.02.0718   126736   Ftpsvc2.dll   (alpha)

WORKAROUND

On the UNC path that the virtual directory is mapped to, grant the correct permissions to the Windows NT account used for Anonymous Access.

Microsoft has confirmed this to be a problem in Internet Information Server.
