NAS/Landisk through SQUID/PROXY

Hello.

I have this Landisk simply known as "Mobile Landisk" by Chronos.

I have successfully configured the device in it's build-in Configuration console; such as giving it a STATIC IP, and changed it's workgroup to WORKGROUP (for windows xp). As well as the necessary SHARES, etc.

Please note: I configured the Landisk by attaching it via Lan cable directly to a stand-alone XP PC.

Our Internet Cafe has 10 XP PC's accessing the Internet through a Linux/Squid Proxy Server.

>> The 10 XP PC's LAN cables are connected to a SWITCH which in return is connected to the PROXY server, and the Proxy box is connected to the Cisco Internet Router.

IP Address for the Proxy is 192.168.0.2 >>> PORT 3128

10x XP PC's IP's = 192.168.0.3, 192.168.0.4, etc.

Now i've configured the Landisk with IP 192.168.0.13.
Then connected the Landisk with it's LAN cable to an open port on the SWITCH.

THE PROBLEM : In "My network places" on XP, I can see all of the 10 PC's , BUT NOT THE LANDISK.

I cannot Ping the Landisk. I iv;e tried several Network Scanner softwares. Nothing. The IP 192.168.0.13(landisk) is reported as DEAD.

I've been battling with this for weeks now.

PLEASE! can someone point me in the right direction.

I am (almost) sure the problem lies by the PROXY configuration, bit i am unsure of what to look out for in the proxy config.

Please help.

Regards,
Jamie.
