has the NAS sufferred a reset? It sounds like Network Interface settings have been changed and are not compatible with switch, and possibly set to DHCP?

do you have a DHCP server on your network?

you may need to program and IP address on the NAS again.

Try using a crossover cable from a known good computer directly into the NAS (no switches in the way).   Make sure everything has an IP number, see if this changes anything.  Don't lso froget that it could be a catastrophic hardware failure inside the RAID.  

So to cover yourself, contact iomega support and ask for troubleshooting networking issues.

I have tried the cross over and yes our router sets the DHCP but no good.

I can try iomega support but they charge £40 and just to be told its a hardware issue for which they no longer have spare parts seems like a waste.

Not sure what else i can do

Does it get to the stage where it can be pinged?
Can you make a traffic dump using idle port on one of computers and a crossover cable? i.e if it sends DHCP or ARP requests etc. (You will need wireshark or Microsoft Network Monitor)
I suspect that your DHCP server does something incompatible...

used to work fine but using a crossover and iomega discovery tool i see the machine but no ip as i think it is asking for one but with cross over no dhcp server

not sure what wireshark is but will give that a go

1) Put the NAS back on the router and your PC, too.
2) Download and save Softperfect's Netscan http://www.softperfect.com/products/networkscanner/
3) Run Netscan and choose your ip address range from 1 to 255 (i.e. 192.168.0.1 to 192.168.0.255)  The NAS will appear in the list of what it finds.
4) Right-click on the entry in Netscan and choose Opens as HTTP
Voila; it should work.

Now; what happened is that the router gave the NAS a new ip address which is why everything got confused.  You would be advised to use the web management to set it to a static ip (i.e. 192.168.0.200) so it won't happen again.
