SYMPTOMS
When a Microsoft Windows Server 2003-based DNS server receives a packet that contains a DNAME resource record, the following event is logged in the DNS log:
Event Type: Information
Event Source: DNS
Event ID: 5504
Description: The DNS server encountered an invalid domain name in a packet from IP_Address
. The packet will be rejected. The event data contains the DNS packet.
Note Event ID 5504 may also be logged because of other DNS packets. If event ID 5504 is related to a DNAME record, it can only be viewed in a network trace. The "More Information" section contains an example of how this network trace may look. The resolution that is provided in this article only applies to DNS event ID 5504 together with DNAME records.
CAUSE
This problem occurs because Windows Server 2003 does not support DNAME resource records as specified in Request for Comments (RFC) 2672.
RESOLUTION
Service pack information
To resolve this problem, obtain the latest service pack for Windows Server 2003. For more information, click the following article number to view the article in the Microsoft Knowledge Base:

Hotfix information
The hotfix that is contained in KB920162 will change the behavior of Windows Server 2003. The DNS server will accept packets that contain a DNAME resource record. Then the DNS server will forward the related CNAME record to the client if the forwarder's answer contains a CNAME record. The KB920162 hotfix will not add full DNAME support to Windows Server 2003 as specified in Request for Comments (RFC) 2672.

To apply this hotfix, you must have Windows Server 2003 Service Pack 1 (SP1) installed.
Restart requirement
