Windows vista is not detecting lacie network space 2 i am trying to install a lacie network space 2 (1T) on a home network. i use windows vista icw avg free virus software. i installed the latest installer (1.4.8). the installer says there is no ethernet disc available, also not after re-installing the disc or rebooting the network router. The disc was detectable on the network in my work office (via mac), where i put some data on it which were accessable w/o problems. any ideas how to solve?

In your office network, for sure, you have a DHCP server who gave the IP addresses to all devices for that network and this seems to be the reason for why you could see your NAS. On home, you also need a DHCP server. You don't say anything about you home network. The best idea is to just make a temporary network with 2 devices: your computer and your NAS by connecting the NAS directly to your computer's network adapter, set the IPV4 IP for that adapter to the same class addresses as your NAS was set by default (usually NAS had "192.168.x.y" where "x" could be 0, 1 or 2 "y" could be any value between 1 and 254, but mostly, 1) and try to access it via http to manage him (need a user name and a password). For NAS default address and username and password, consult NAS user manual. Access it with from your preferred browser using: \\192.168.x.y
Once you gain the control, cut off his DHCP service and tell him to accept the IP address from the network defined DHCP. (btw: one normal DHCP server is allowed on one network! Cascaded DHCP also is allowed, but it's a little bit complicated)
Good luck!
