SYMPTOMS
After you add an alternate computer name to a domain controller that is running Microsoft Windows Server 2003, you later experience Domain Name System (DNS) name resolution problems when you try to access that server by using its alternate name. If you restart the server, the problem is temporarily resolved.



CAUSE
This problem occurs if the server where you configured the alternate name is configured to dynamically register its name in DNS. The primary name of the server is updated in DNS at the interval that is specified in the DefaultRegistrationRefreshInterval value. However, the alternate computer name is not updated. As a result, the DNS record for this alternate computer name is eventually scavenged (if aging and scavenging is enabled), and you experience problems when you try to access the server or the services that are hosted on the server. When you restart the server computer, both the primary and alternate computer names are again registered in DNS.
