I've just bought the DNS-323 and I'm having a few problems with it.
First some details
Firmware is version 1.07
2 x 1.5TB drives in Raid1 configuration
configured on wireless network as workgroup
static ip address
No users set; no groups set; no access permissions set; no quotas set
visible on network,
XP Pro + SP3
drives mapped...no probs yet.
My wireless router is a zyxel P-660HW-D1,
I have turned off all firewalls and antivirus (just for now) but problem still persists.
My problem is this when I go to copy files (large or small) to the DNS-323, I get an error saying
"cannot copy myfile.

: it is being used by another person or program"
or
"Cannot write data. The specified network name is no longer available" and I lose network connectivity as the link to the wireless router resets
Any help would be really appreciated...
