  1. use these commands in this order:

         nisupdkeys -CH master.server.name. groups_dir.domain.name.
         nisupdkeys -CH master.server.name. org_dir.domain.name.
         nisupdkeys -CH master.server.name. domain.name.

         (This CLEARS the public key for the HOST "master.server.name" in this
  directory.)

  2. Kill rpc.nisd and restart it at security level O then run this command:

         nistbladm -R cname=master.server.name. cred.org_dir.domain.name.
         nisaddcred des

         <This deletes the old credential and creates a new one.>

  3. Shutdown and restart any replicas of org_dir.domain.name. at run level O

         nisping org_dir.domain.name.

  <This propogates the new key pair to the replicas.>

         nisdupdkeys domain.name.
         nisupddkeys org_dir.domain.name.
         nisupdkeys groups_dir.domain.name.

         <This puts the new credential in the effected directory objects.>

  4. Kill and restart all rpc.nisd servers at level O to security level 2.

	   Another possible cause of df & du disagreeing is if the files are
	   being 'hidden' under a mount.  I ran into this recently where I
	   had a large number of files in /tmp (from adding patches in single
	   user mode) that were on the root partition.  Thus when I was
	   looking for them in multiuser mode, I couldn't find them because
	   of the tmpfs overlay. I exported the root partition via NFS and
	   upon mounting it found the hidden files and deleted them.

          The physical address of each station is set by network
          management to a unique value associated with the station,
          and distinct from the address of any other station on any
          Ethernet.  The setting of the station's physical address
          by network management allows multiple multiple data link 
          controllers connected to a single station to respond to 
          the same physical address.
