I linked up my mac with a PC based network and everything was working fine...but for some reason I can no longer see the network from my mac. I can see my computer from other computers and I can still access the internet so I know the connection is working. I guess it is a software conflict. But where do I start looking? I am on a Power Mac G5 running Tiger 10.4.11. I have upgraded all the software I can. The problem is intermittent after 3 or 4 restarts I can see the network again!
