So.... I addressed this problem a few weeks ago but it's arisen again. I've got an OS9 program (FileMaker Pro) that connects to a Host server to work on databases. I operate everything else on OS10.2.8 and operate the FMPro in classic at the same time. This weekend I was having issues connecting to an airport and I (under control panel / Network) created a new location. Now when I try and query the Dbase from FMPro I get an "Appletalk Port Busy" error and it won't connect. I've made sure appletalk isn't on in OSX but still nothing. I've tried setting my connection to the old Location which was there before. Any suggestions?
