Today we finish with part 3 of our 3 part series on the IAMW. Part 1 can be found here and part 2 here.
If you choose“I want the server to manage the domain name for me” the following Internet DNS records are created by the wizard and registered at the partner registrar.
If you choose “I want to manage the domain myself”, you must manually create and maintain these records with your DNS registrar.
The following DNS records are created locally on the SBS server. This is done in all scenarios.
SBS is able to keep external DNS records up-to-date by making a connection to the partner registrar that is hosting the customer’s domain name and DNS records. SBS uses the “Dynamic DNS Client” service to query the partner registrar to see if the external domain IP address has changed (every 10 minutes by default). If so, the service will use the new IP address in a second call to update the host A record for the domain.
The Dynamic DNS Service will ensure the following
After SBS 2008 setup completes, the Dynamic DNS Client service remains inactive until you choose to configure your domain with a partner registrar. Once you do, the service will be set to automatic and begin querying the registrar every ten minutes by default.
If the IP address hasn’t changed in 20 days, the service will refresh it at the registrar. This will ensure the provider doesn’t shut down dynamic DNS updates without our knowledge.
If you have a static IP you can disable this service.
In an effort to standardize the remote connection naming convention, SBS 2008 prefixes “remote” to the .domain.com as its standard naming configuration. Examples of this can be seen through the records created for applications like Remote Web Workplace and Outlook Web Access. The Self-Signed Certificate is also stamped using this naming convention as well.
The SBS Web Applications site’s host header value is stamped with the chosen domain name. A leaf SSL certificate is created and bound to the SBS Web Applications site on port 443 and to the SBS Sharepoint site on port 987.
For instance, if you have chosen the name “remote.constoso.com”, and external DNS records are correct, you would access the following resources as so:
A certificate distribution package is created the first time you run the IAMW for deployment to non-domain joined clients and mobile devices. For more information please see:
The autodiscover record written above is incorrect. It needs to be _autodiscover._tcp.FQDN
Good catch Brian, I have updated the post.
What form is the MX record, being fairly inexperienced with DNS, I can't tell whether the second record in the table is an MX or CNAME.
What form might the record take for e.g. MyDomain.com?
