    There are several possible causes for this behavior.

    1. Two (or more) computers on the local network have the same Bonjour name, such as "X's-MacBook-Pro.local". Resolve the name conflict by renaming one or more of them in the Sharing preference pane.

    2. You have two simultaneous connections to the same local network: probably Ethernet and Wi-Fi. If applicable, disconnect the Ethernet cable or turn off Wi-Fi.

    3. A Mac wakes from sleep due to network traffic. This is a bug in OS X that may only affect some models.

    4. A device that gets its network address from the router wakes from sleep, and the address it was using before has been assigned to another device.

    5. A third-party wireless router has incompatible settings or firmware. In that case, refer to the manufacturer or ISP for support. Restarting the router may help, temporarily.

    6. If the router is an Apple device, it may need to be restarted.

    7. A third-party Bonjour device on the network is malfunctioning. Finding out which is a process of elimination.

    8. There is more than one DHCP server on the network. Typically, there would be two or more wireless access points configured to act as routers.

    9. See also this support article.

    There are a couple of threads discussing the issue. In my own case restarting (power cycling) my Airport Extreme Base Station resolved the issue so far. Give that a try and see what happens.
