You could check whether this is caused by some network routing problem also ? Are you are on the same network as the server ?? If so, one way to sort this out would be to use ip address in your network config files (tnsnames.ora, listener.ora). Ofcouse, you should be able to do a ping to your server and also tnsping.

HTH.

P.S.: You could post the full text of your errors.
