   5.  No idea unless there is group policy to override this.  I disable =
NBT and have for years.

   6.  No.  You did not not need to disable LMHOSTS lookup either.

  1. What is it trying to do?
  2. Why is it doing it every 12.5 minutes?
  3. How can this be disabled?
  4. What is the ramification of disabling NBT (NetBIOS over TCP)?

  I went to Network Connections,  Properties, TCP/IP, Properties, =
Advanced,
  WNS, (whew) unchecked "Enable LMHOSTS lookup", and selected
"Disable =
NetBIOS

once
  again LMHOSTS lookup was enabled and NetBIOS was set to "default".

  5. Why did it do this?
  6. Is what I did the way to disable NetBIOS, or do I also need to =
remove
     "File and Printer Sharing for Microsoft Networks"?

  Thanks.
