Please help with yp binding problem

[Jamie Gulden]

   I am having a problem with yp (NIS) and was hoping someone could
help out.

   PROBLEM:  When a 4D/25 is bound to a yp server that goes down it won't
             rebind to a different server.

   INFO: 4D/25TG w/ IRIX 3.3.1 and NSF 3.3
         3 sun servers running SunOS 4.1.1

   WHAT HAPPENS: The PI is running ypbind and ypwhich returns the hostname
       of one of the servers.  The PI will bind to any of the three servers
       at boot depending on which responds first.  If that server goes down
       the PI will start printing the following message:

yp server not responding for domain ".VIS.ColoState.EDU"; still trying (v2)

       Typing ypwhich returns that the domain is not bound.  The only way
       I have been able to get it to rebind to a different server is to 
       reboot the system.

   WHAT I HAVE TRIED:  Looking in the IRIS NFS manual under debugging a
       yp {client|server} the exact error message is given but all of the
       suggestions it gives are allready being done (ypserv is running on
       all machines and none of the machines or the network are overworked,
       the domain name is correct on all machines, other machines are
       getting services off of the other two servers just fine).  Our suns
       work fine and will rebind when needed to a different server.  Also
       ypset won't let me set the server.

   Any help would be greatly appreciated, thanks apriori,  Jamie.
