"The file or folder does not exist" when renaming or saving to DFS share from a Windows 7 computer


View products that this article applies to.

Symptoms

When connecting from a Windows 7 computer to a DFS namespace (network file share) located on Windows Server 2008 R2, renaming or saving files located in the second subdirectory depth level (for example, z:\d1\d2) may fail with:

"The file or folder does not exist."

Also, if a file is saved to the z:\d1\d2 directory, the file will actually appear in the z:\ root directory instead.

Cause

This problem can occur if the Windows 7 client machine connects to the DFS network file share using the \\ipaddress\SHARENAME syntax, but the client is unable to connect to the server using its name (i.e. \\servername\SHARENAME ). When a Windows 7 client connects to the \\ipaddress\SHARENAME, the server indicates that the share name is actually a DFS namespace. The client internally uses the DFS server name to track the location of the network connection, but if name resolution to the server name fails, the folder path is not tracked correctly.

More Information

While the problem can be reproduced when connecting from Windows 7 to Windows Server 2008 R2, it requires a DFS namespace to be configured for SHARENAME so that the "DFS capable" bit is set on the SMB2 Tree Connect response.

After connecting to a DFS share on the server using the \\ipaddress\SHARENAME syntax, no error is displayed when name resolution to the server fails, so the file/folder access problem is not apparent.

Workaround

To correct the problem, ensure that the Windows 7 client can connect to the server using its name, instead of its IP address. Or, reconfigure the client so that name resolution to the server name is successful. For example, make sure the client's DNS server name is correct, or add a hosts file entry to indicate the correct IP address / name mapping.

For example, from an administrative command prompt, start Notepad and open c:\windows\system32\drivers\etc\hosts , and add an entry. For example if your server name is "ServerName" and its IP address is 10.0.0.1, add:

10.0.0.1 ServerName

NOTE: The client may be able to work around the problem by always connecting to the server using the \\servername\SHARENAME syntax. This will cause the client to experience a connection error while connecting to the server if name resolution fails.
