samba - Jun 2016 - Shared printers are shown up only after 15 minutes on the Windows clients

After updating our Samba Active Directory Domain Controller from Samba 4.1.6 to
4.3.4 it takes 15 minutes now
until all shared printers are shown up on the Windows clients, after our server
has started.
Although this is not a big problem, because our server is running 24 hours a
day, i wan't to fix this. :-)

The CUPS error log says: 

[11/Jun/2016:14:44:39 +0200] Unknown directive BrowseAddress on line 9 of
/etc/cups/cupsd.conf.

When i look into cupsd.conf the line 9 looks like this:

BrowseAddress @LOCAL


There is also an entry in log.smbd:

[2016/06/11 15:10:05.421844,  0]
../source3/param/loadparm.c:3217(process_usershare_file)
  process_usershare_file: stat of /var/lib/samba/usershares/samsung_printer$
failed. No such file or directory

This error is always shown when using one of our Samsung printers, although
there are working fine.
Our usershares folder is empty, because we are using other folders for our
shares.


Here is our smb.conf:

It would be nice if anybody can help me to fix these hopefully
"little" errors.

Thx
