A puzzler: When trying to unzip files on my LAN drive I get the error
message "Not a ZIP File". When clicking an *.XLS file on the LAN drive I
get the Windows error "Not a valid Win32 application". Well, I know it's
not an application. Harumph. Grumble.

Everything else works. Also when I copy those files over to a local PC
it's ok. The drive is a Western Digital MyBook and AFAIK the little PC in
this one runs Linux. Did anyone else have that happen with a Linux file
server? Any fixes? It's not a huge problem at all, just curious.
If you use NFS you probably have a corruption problem i.e. Network Failure
System operating as designed ;-).

Thanks, that could be. To be honest I don't know which file system it
uses. I was hoping not NTFS. Oh well.

If it is SMB/Samba - the drive appears as it would do in windows maybe one
of the network ports inbetween is flipping between 10 & 100 MB because
autodetect does not work. Again corrupting data. SMB generally works on a
good network - WiFi is *crap* BTW.

Data doesn't get corrupted. Even super-large files are perfectly ok.
It's just that the PC wants to start them as an application while it
treats local files with same extension as data files and launches them
correctly into (and not as) an application.
It sounds like a problem with 'name mangling' in the Samba configuration
of the server. There are numerous settings in a Samba configuration that
control how file names (and permission bits) are mapped between the
Linux file system and Windows.

If your server is a 'network appliance' there may be nothing you can do,
but if you can play around with the Samba configuration files (shell
root access), you might be able to change this behavior.

Guess I'll have to live with it then. Western Digital allows users
precious little access :-(
There's one other thing you might want to check: See which 'Zone'
Windows thinks this server is in and whether the appropriate application
launch permissions are set.

Any idea where to check that? Tried under properties, admin etc. Nada.

Nope I've seen something about 'Zones', probably under firewall stuff,
when attempting to help some poor slob with their Windows boxes. But I
don't have one myself.

Ok, the firewall is hardware here and all this is behind it. This firewall has two zones: The one on the inside is treated as friendly territory, the one towards the WAN is treated like the Bronx at 2:00am.
