    I have a small network at home, with one machine acting as a sort of file/printer server.

    As of this morning none of the other machines I have can access it or print to it.

    On the router the connected devices report all the machine names, but the machine in question is listed as "UNKNOWN".

    I assume this is the problem so when I refer to the machine name for files or to print to it cannot be resolved!?

    If I do a PING to the IP address of the machine it fails as well!

    If I start in STARTUP mode with network support, I CAN see the machines name appear correctly in the router?!

    Help!?!?

    ps: The machine in question can access the other machines.
