Problem wth AFP in golden triangle…

Hello! I have touble getting my clients connecting to my OS 10.4.7 server using AFP. I have tried setting up an automount but it wont work. I have tried using ? K and disovered that this does not work either. I canged it to smb:// and it immediatly worked. I can find a way to use smb for automounts from workgroup manager, so I need to fix my afp problem.. Both domain and local admins can connect via afp, but none of my clients, so it looks like a permissions problem. However I cant find anything wrong with my permissions... Does anyone know how to fix this? Maybe I have overlooked something obvious? Any help would be greatly appreciated! Thanks! Thomas
