The problem is not on your local machine. It is with the primary
name server for your domain. Without real information that is about
as much as we can tell you. You need to update the DNS record to add
a record for server.mydomain.com. What type of record depends on
what you are trying to do. How you do it depends on who is providing
the name servers. From what little you have told us, it sounds like
you are getting the name servers as part of your domain name
registration. There is probably a web form to modify the records.

One thing to keep in mind - when you change the DNS records, it
takes a while for the changes to show up everywhere. A lot of ISPs
are running caching name servers, and if the entries for your domain
are in the cache, then they have to expire before the server checks
again. This can include an entry for server.mydomain.com that
basically says that the name server for the mydomain.com says that
server.mydomain.com does not exist.
