SmartWare Pro Doesn't recognize Network backup location

I’m running Windows 7 Service Pack 1,  64 bit and version 2.4.2 of WD SmartWare Pro… on one machine.

Presumably the same version on a Windows Vista 32 bit on the other.

in both cases I’m trying to back up to a Linksys NAS, MNH410, but as far as the source computer knows its just a network drive. I can’t imagine it matters what it is…

sounds like I’m SOL, … and annoyed…
