Small Business Server & WINS

I am installing small business server 2000. When setting up WINS in DHCP i set up 46 NBT mode and it defaults to ox1 and not oxh (hybrid) mode as before with W2K or NT4. Any ideas what the difference is or is this better. Microsofts site isn;t that helpful and this is the first time i have used small business server.

Thanks

Shaun
