RE: unable to join domain from dmz

["Steven A. Fletcher" <sfletcher () integrityts com>]

But, for a Windows NT 4 domain to function best, a WINS server should
already be set up.  Otherwise, you have the potential to end up with a
ridiculous amount of broadcast traffic.

I don't know where people got the idea that WINS is hard to setup or
maintain.  I find it extremely easy.  I would be more than happy to help
anyone who needs help in that area.

You can do this by adding an entry in LMHOSTS also, you can google
for instructions - simpler than setting up WINS.
