We have a Pc and laptop, both connected with a cable to a router. It's all been going fine and we've been sharing files, printers and internet. Now all of a suddent when we try to access share resources we get a message saying 'yyz computer not accessible. YOu might not have permission to use this network resource, etc etc.' although we can still get online ok. I've checked all the settings and rerunt the network wizard but not result. Any suggestions?
