Crystalis:~ Jamie_Standard$ smbutil lookup Crystalis Got response from 192.168.225.1 IP address of Crystalis: 192.168.225.1 -- If you're not part of the solution, you're part of the precipitate.

Any advice? > > Have you tried the usual way of setting your computer name: > > System Preferences -> Sharing -> Computer name: Apart from the obvious, the first thing I'd check is how the computer is connected to the network. Do you have multiple active network interfaces going to the same network, typically Ethernet and Airport? In this situation, each interface will end up with a different IP address, and you could get a scenario where the computer's Bonjour transmissions via one interface are picked up via the other interface, and assumed to be a different computer on the network with the same name. This will trigger the auto renaming of the computer. I haven't noticed this myself, but I usually turn off Airport as soon as I plug in an Ethernet cable for the same network. This may only occur in specific conditions, such as an unreliable or busy WiFi network, or race conditions between Bonjour and changes of IP address such as AutoIP to DHCP (acquiring a lease) or DHCP lease expiry and getting a new IP address. None of these would cause any problems if the computer has a single connection to the network, nor if the two network interfaces are going to different networks. A related issue is a misconfigured Ethernet which has a loop due to two connections between switches. (Most home users won't be in a position to encounter this - you would need at least two Ethernet switches/routers.) This can cause all sorts of weird problems due to computers receiving their own broadcasts. Our office Windows network basically stopped working when this happened, due to utter confusion in the NetBIOS name resolution protocol. It was repeatedly going through re-election of the master browser or something like that, and flooding the network. -- David Empson dempson(a)actrix.gen.nz
