Nope - the other working PC is directly connected and I've directly connected the non working PC direct to the router with the same issue.

i don't suppose the router is only set to dish out DHCP to wireless clients, is it? I doubt the zyxels have the option to split, but take a look...
DHCP message - without looking it's from DHCP Client saysing it could not obtain an IP address...

The other PC is working so I know the DHCP server is working correctly.

try the following commands....


ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew

does sound likely to be a firewall thing though. try turning them all off and try again

Good shout on the commands - I've tried the ipconfig / renew etc but not the flush and register...

Firewall - the PC is running KIS2009 - and so is the working PC...
