all my emails that i sent to aol  all the sudden started to being rejected.    i call them i they say it is because AOL will not accept SMTP connections from IP addresses which have no reverse-DNS (PTR record) assigned.

You can check and learn more about your reverse DNS on the AOL Postmaster Web Site: http://postmaster.aol.com/info/rdns.html

Please setup a reverse DNS entry for any IP addresses that are having a delivery issue. Once reverse DNS is setup, the block on those IP addresses should be removed within 48 to 72 hours.

Can somebody help me do this?   i am a rookie when it comes to DNS

Thanks

If you have access to your DNS records, then you must go into the Reverse Lookup Zone and set a Name and IP there, it is a PTR record. This must be on your External DNS. If you do not host your external DNS, then you must do it through your provider, request that they set your Reverse Lookup for the SMTP servername and IP Address.

I do not host my dns..  my ip does host it and they send it back to my web server that is located in my office.   so you are telling me that i do not have to do anything from my local dns server?

No, the External DNS server has to have correct entries for both the Forward and Reverse lookups to your SMTP server. Call the provider or email them and tell them you require a Reverse Lookup for your MX record.

The MX record is your mail exchanger, which is the SMTP server. They should know eactly what to do, and if they cannot do it, they need to tell you why.
