Copy file from HTTP Distribution Share

This may sound simple but it has me stumped at the moment...

I am looking to copy a file from an HTTP distribution share , down to a machine that has LANDesk agent installed, but is not on our domain.

The http share can be reached from the non domain device, so it is not an access rights issue.

From looking at the documentation I have tried the following , without success.

%LDMS_CLIENT_DIR%\sdclient.exe /f /p="http://LDMS_CORE/distribution/FILES/FILE.TXT" /dest="c:\landesk\FILE.TXT" /lan=90 /wan=60

Is this format incorrect or am I doing something wrong ?

Any help would be gratefully received.

Thanks
