When you add an SRV record (also known as a service record, which provides information on available services) to your registrar (a company that is accredited to sell Internet domain names) website, users who use an instant messaging client other than Windows Live Messenger can communicate with users in your domain.
The following steps are general and might not apply to your domain registrar. If you can’t find or edit the SRV record information for your domain, contact customer support for your registrar.
To add an SRV record:
Sign in to Windows Live Admin Center with your Windows Live ID. (Your Windows Live ID is the user name and password that you use to sign in to any Windows Live, MSN, or Office Live sites and services. If you have a Passport Network, Hotmail, or Messenger account, you can use it as your Windows Live ID.)
Under Your domains, click the appropriate domain.
In the left pane, click Domain Settings.
Under Administrator status, make a note of the SRV record information and the DNS settings.
Visit your domain registrar's website, and then sign in to your account.
Find the management or DNS settings area where you can edit the records for your domain. If you have more than one domain, select the domain that you used to sign up for Admin Center.
Type the SRV record and DNS information, and then save your settings.
Make sure that the settings that you type for your domain on your registrar's website match the settings in the Domain Settings section of Admin Center.
After you change your SRV record, your domain is configured for Admin Center. However, your registrar must propagate the change to the Internet, and this might take up to 48 hours. Check Admin Center frequently to verify that your changes have been completed.
When you transfer your SRV records to Admin Center, your registrar doesn't change.
With some registrars, the TTL (Time to Live: the time that a packet of information remains active on a network) setting is optional. If your registrar doesn't allow you to set a TTL, you can ignore it.
