unable to sync browse lists

[John Lusk]

I'm having two problems.  I encountered the second while trying to set
up a clean environment to work on the first.  Can somebody tell me if
(a) I've done something obviously wrong, or (b) this is a known Samba
bug?  Any help is appreciated.

John.

First problem:

   From nmbd:

   domain_master_node_status_fail: Doing a node status request to the
   domain master browser for workgroup [workgroup name deleted] at IP
   [PDC/DMB ip address deleted] failed. Cannot sync browser lists.

Second problem:

   I don't get the above message, and browse sync w/DMB seems to
   succeed, but the Samba server's name (and shares) don't show up in
   Desktop Explorer (and, presumably, in Network Neighborhood, since
   they're the same thing, right?).

Pushing a little deeper into the first problem with a symbolic
debugger and higher debug levels, the node status query failure is due
to a timeout.  It seems that the DMB (an NT server running 4.0 + SP3,
SMS, Cheyenne Anti-Virus, NT Server ResKit 2 and no hotfixes) simply
doesn't respond to the node status query the Samba server sends it
(from a different subnet).

I have read docs/BROWSING*.  I've read the section on cross-subnet
browsing in Blair.  It is, of course, possible that I missed
something.

I've gone through the steps of DIAGNOSIS.txt.  All steps succeed up
to step 10 (using file mgr to browse the server).

Network topology for the relevant machines:

   For problem one:

      Multi-homed Samba server (Samba 1.9.18p10 on Intel DG/UX
	 R4.20MU03) with interfaces on subnets A and B;
      NT WINS server on subnet C;
      NT PDC (and DMB) on subnet C;

   For problem two:

      Same multi-homed server as above, but in a new workgroup/domain
	 (this one's browse list appears in Explorer);  
      Same NT WINS server as above;
      NT PDC (for new domain) on subnet A;
      2nd Samba server on subnet D (this is the one whose browse list
	 fails to show up);

smbd and nmbd run as root, so the problem w/non-root apps reading port
137 doesn't apply.

My smb.conf is attached (edited a bit because I don't want to give out
ip addresses, etc.):

---------------- (begin smb.conf) ----------------

   interfaces = <samba host's ip address>/24 \
   	<2nd ip address, for multihomed server>/24

   deadtime = 30
   lm announce = no
   dns proxy = no
   wins server = <DNS *name* of NT WINS server>

   workgroup = <all-caps short name>

   ; Recommended settings (docs/BROWSING.txt) for cross-subnet browsing
   ; in a workgroup

   ; PDC is domain master browser (always).
   domain master = no
   local master = yes
   ; Only one machine per subnet should be a preferred master.  If two machines
   ; are declared to be preferred masters, they will constantly force elections
   ; (every 5 minutes?).
   preferred master = yes
   os level = 65

   security = user
   read only = no
   create mask = 0774
   directory mask = 0775
   guest account = ftp

[entry for 'ftp' from /etc/hosts:
ftp:*:39:39:  FTP guest Login:/var/ftp:/sbin/sh
]

   guest ok = no
   read only = no

   ; Optimizations.

   ; wide links = no in order to provide similar semantics to Unix:
   ; symlinks to a non-mounted NFS filesystem will fail under Unix.
   ; Also, getwd cache = yes require 'wide links' to be 'no'.
   wide links = no
   getwd cache = yes
   read prediction = yes
   socket options = TCP_NODELAY
