Hi tkw,

If you can get a response from the DNS server when pinging it from SwitchB, it sounds like you either don't have the PC connected to SwitchB configured correctly or the port it is connected to is not functioning correctly. You switch configs are correct. SO make sure the PC port is untaged on VLAN1 and that the port's status is UP.

Can you get a ping response from SwitchB if you ping it from the PC? If that works, can you then get a response from SwitchA?
