I just spent 30 minutes fulfilling a request of my sons to do something should have taken about 2 minutes. He wanted to transfer files from our Windows ME machine to one of our Macs. If they had both been Macs it would have taken a couple of seconds to do the connection. Mac OS X can see Windows networked computers, but ours didn’t show up and trying to figure out how to get it on the network took a lot of time and was ultimately fruitless.
Eventually I turned on FTP access on the iMac. Which involved one click in System Preferences. Then I used IE on the Windows machine to connect via FTP entering the username and password in the URL.
I hate windows.
