Novell NetDrive
The best client. Install it and you get a new drive accessible from any application. Also, it doubles the performance of Windows Explorer.

search for netdrive.exe

Firefox
You can download stuff using Firefox. It works fine.

Windows Explorer / Total Commander
Doesn't work properly. Machine hangs during copy.

Server
Symbolic links don't work in mod_dav - they work if you use the browser, but not in the filesystem implementations.
