[GoDaddy and Win2k3] Help Setup our DNS

Please help me setup our domain name to point to our server.

Please give me some guide how to do it.
Our server provides HTTP, HTTPS, E-Mails.

I don't know how to configure it.

Only someone with a Godaddy acc. can precisely help you out.I don't think it will be that difficult even for a newbie.

I know there are people here w/ GoDaddy Accounts.
I've read some posts that they have domain names hosted by GoDaddy.

Anyway, do you know how to setup a DNS?
I'm checking our domain name in DNSStuff.com and found out that there are many errors in our DNS.

How to make our server not an open relay?
Please help me w/ this?

You're asking a few different questions here but not providing any background. What DNS server are you using? What are the problems that you are having? What's the domain name?

Without mentioning what mail server you're using you're not going to get any specific answers, but you need to require authentication to send email to external hosts via your mail server.

I think I already give enough details from the title to my posts.

Our DNS provider is GoDaddy, our Mail Server is a Win2003.
Maybe you can help me w/o providing our Domain name because our server's security is still weak.
I hope you'll understand this.

What mail server software are you using?

Only the IIS6.0 SMTP (built-in SMTP of MS Windows 2003).
I found some walkthrough how to configure it but my messages were always blocked.
I can't figure out what to do.
