Upgrading Child Domain to Win 2003

Archived from groups: microsoft.public.win2000.setup (More info?)

I’m planning to upgrade a server in a child domain from Win NT 4 to Win
Server 2003. What I would like to do is a fresh install since there is only 6
user and no many other resources to configure. This server (domain) links to
our Head Office thru the internet. The current domain name is “companyB�,
after the fresh install it would change to “companyB.lan�. The questions I
have are:

1. Is doing a fresh install a good idea?

2. How do I go about preparing the Parent Domain? Just delete the child
domain?

3. Is .lan a good extension for a private LAN domain? I had some problems
when we upgraded the parent domain, because the consultant named the domain
as companyA.com and users were no able to access our website, so I had to add
the www and ftp entries to our DNS.

Any other advice would be welcome.

Thanks in advance.
