NetBIOS name reg/resolution problem -- multiple net interfaces, Samba 2.0.7, Solaris 7, ClearCase

I am having problems with Samba 2.0.7 running under Solaris 8. We are using
Samba to use ClearCase on NT clients with UNIX servers. The machines it
is running on have multiple network interfaces. 

I've tried several approaches, none of them seem to work.

System Hostname and IP addresses. Hostname is zrtps078.
Hostname        IP address      Netmask
zrtps078        47.111.70.82    255.255.240.0
zrtps079        47.140.7.213    255.255.240.0
zrtps07a        47.202.32.217   255.255.240.0

1. Run Samba as a single daemon, bind to all interfaces
   Files: smb.conf, smb.conf.global.zrtps078, smb.conf.share.zrtps078 (see end
   of message for file contents)

   Samba only registers the machines primary hostname, zrtps078.  Clients are
   often unable to bind to the share using one of the alternate interfaces.

   For example:
   net use * \\zrtps078\export
   net use * \\zrtps079\export
   net use * \\zrtps07a\export

2. Run separate smbd/nmbd for each interface.
   Files: smb.conf.zrtps078, smb.conf.global.zrtps078
          smb.conf.zrtps079, smb.conf.global.zrtps079
          smb.conf.zrtps07a, smb.conf.global.zrtps07a
          smb.conf.shares.zrtps078

   This ends up generating lots of errors in log.nmb about being unable to
   register/refresh names. Apparently, nmbd attempts to register the primary
   hostname with each instance even though "interfaces" and "bind interfaces
   only" are specified.

   Again, the net use commands above don't always work.

3. Run single smbd/nmbd but specify the alternate interfaces with "netbios
   aliases".

   Files: smb.conf, smb.conf.global.zrtps078.new,
          smb.conf.shares.zrtps078

    I'm still getting messages about being unable to register/refresh names
   and the net use command still don't work.

We've also made sure that "Enable DNS for Windows Resolution" is turned on.

This is having a significant effect on our environment. Any suggestions would
be welcome.
