WINS-server broken?

For a long time WINS-server has worked for me by adding "wins support = yes" in the "SMB Extras" section, but after I upgraded from 6.8.3 to 6.9.2 I keep getting this in my log:

Anyone know if the support for WINS has been removed or if something else has changed that break this?

(I use WINS only to get name resolution when connecting to my network via VPN, so if there's another way to get that working I would be thankful for some tips on how to do that.)
