Name resolution in a Windows environment

[Scott Henderson]

It seems like you've gotten a lot of good advice, so I'll try
not to duplicate it, but I've got a few comments, and I may be 
able to make a couple of things clearer...

This is important.  Run these commands to find out how the WINS
boxes are doing their name resolution.  Try to do the same thing
as they are, so you'll pick up any changes made to the network.
If they're using WINS, you use WINS, likewise DNS.  Point to the
same servers for these services.  If they are DHCP clients, best
bet is you be one, too, and you'll pick up the correct settings.

You can do this, but better to use WINS.  Then as machines
change, you'll stay with the flow.

DNS and WINS are similar, but otherwise not really related.  WINS
is specific to MS, and resolves "NetBIOS" names to IP addresses.
The Win boxes will just call their NetBIOS names the "Computer
name".  They'll also have a "Host" name (listed in the DNS tab of
the configuration), and USUALLY these will match the NetBIOS
name. DNS resolves between IP addresses and host names, WINS
resolves between IP addresses and NetBIOS names.

By now I think you understand this not to be true.  The only
question is HOW you will resolve their names.  So, for example,
You can set up a mapping of NetBIOS names to IP addresses on your
local machine (/etc/hosts), or you can use WINS.  The latter
method means you won't have to manually keep your mappings up to
date.

Resolv.conf is where you'll indicate your DNS servers.  But
you'll probably need to tell you box where the WINS server is,
too.  That's in smb.conf:

	wins support = No
	wins server = xxx.xxx.xxx.xxx

Again, match up to the other machines.
And get DHCP to do what work it can for you!
