I think enabling IPv6 will assign only link local address... not sure but i think its not give configuration for the default route... so you can have communication between two devices on the same link but not out side that...

Is the switchport on the switch in the same VLAN as the interface attched to the router?
Is IPv6 configured on the switch?

You have to assign a /64 prefix (either unique-local or global) to the interface for the router to send Router Advertisement (RA) messages and therefore for your PC to get a gateway.
It would help your PC to get gateway information if it only had a link-local address.
Hope this helps,

I have some questions to ask you:
have you configured your cisco router as a DHCP server?
if yes, have you typed the key command "default-router" to setup a default gateway on your router?
if yes, have you enable your xp pc as a DHCP client?
