Thanks, I was aware of the 10 user limit.....apparently the people in charge of purchasing the network equipment however are not. I have no idea why the would even implement a "File Server" using a laptop, let alone a 32-bit Vista laptop.
The NAS I'm looking at (QNAP TS-219P+ http://www.qnap.com/pro_detail_feature.asp?p_id=182
, is running on Linux. It will not be attached to any Windows based equipment, but run directly through the switch and maintained via web interface.
But basically you answered my question....since its a Linux based NAS I should be fine.
