Network issue -switches plus lack of Internet.
I've got a little problem!
School electrical rewire over the summer but servers were kept live but did not have network access. Part of the rewire included some fibre between two new HP Pro-curve switches. All back on today but initially the DHCP Server was not handing out DNS Addresses. Restart of service fixed that. Currently only local access, router pings ok but refuses to give Internet. Also trying to get the HP switch to talk over fibre to a Cisco switch downstairs is not working despite the supplier telling me the Gbic is correctly configured.
Any thoughts please?
