One of the employees at the company I support had tiger put on her Mac Laptop and sharing enabled on it. Ever since this happened, she has been getting an error message saying that the local hostname already exists on the network no matter what we change it to. I thought that the AirPort may be conflicting, but I disabled it and got the same message. I disabled automount, disabled sharing, and still the same message comes up over and over again about every 5 minutes or so. When I am in the network preferences for long enough, it will say another application has changed the preferences and none of the changes that I made were saved. Not quite sure what to do beyond this point. Thank you in advance.
