Lmhosts in Unix

I would like to know how to use lmhosts in Unix environments. My Company run Solaris ver8, Sco Unix and NT 4.0. We have NT on 6 sites and Sco Unix on 8 sites and 7 sites are on Solaris. Netlink is installed on non NT sites. I would like to create trust on non NT sites across the WAN, but WINS tend to play up at times. How do I configure lmhosts on the SCO and Solaris sites.
