DNS services

hi all,

I've a DNS installed in the Windows 2003 Server ... I've added the local servers address into the DNS forward and reverse lookups ...

problem 1: (200pt)

when I run NSLOOKUP, the error given to me was name not defined

problem 2: (150pt)

i have a registered domain (only) with the ISP and has redirected the delegation to my webserver. This is working well. But is there a way to register the subdomain extensions in the DNS without paying the ISP and will be able to lead to my domain? (E.g. abc.com (domain), abc.com.au (subdomain) or au.abc.com (subdomain))

please explain steps

problem 3: (150pt)

do i need to register with the ISP for a MX record for email or I can set it in the DNS?

This might be a problem with a reverse lookup zone.  Configure a reverse lookup zone on your windows DNS server.  Go into the DNS console and create a new REVERSE lookup zone.  Then create a PTR record for your DNS server.  Then retry NSLOOKUP

Yes, if you have an Exchange server, for example, you will need to add an MX record for your registered domain name.  To do this, contact your ISP or domain registrar.  

Add these records:

"A" record = mail  (because your creating this for your registered domain name on the internet, it will become mail.internetname.com)
"MX" record =   MX = 10, mail.internetname.com


Example:

experts-exchange.com    MX preference = 1, mail exchanger = mail.experts-exchange.com  <--here is an example of an MX record.

experts-exchange.com    nameserver = ns6.experts-exchange.com
experts-exchange.com    nameserver = ns5.experts-exchange.com
mail.experts-exchange.com       internet address = 64.156.132.251  <-- the MX record points to an "A" record that relates to the Public IP of the mail server.
ns5.experts-exchange.com        internet address = 64.156.132.253
ns6.experts-exchange.com        internet address = 64.156.132.252

I've never had to deal with this.  I think you may want to conact your domain registrar to see if this is possible.  I'm not sure, but you might simply need to register domain.com and subdomain.domain.com with them.  Once this is registered, you can have them create "a" records or what ever you need to direct traffic to your web sites...

Well if the ISP completely delegated the control over to your DNS than you would have no problem creating subdomains.
