Description: This security update resolves a privately reported vulnerability. This spoofing vulnerability exists in Windows DNS clients and could allow an attacker to send specially crafted responses to DNS requests, thereby spoofing or redirecting Internet traffic from legitimate locations.

Domain Name System: Stores and associates many types of information with domain names; most importantly, it serves as the phone book for the internet, translating human-friendly domain names and computer hostnames into computer-friendly IP addresses.

When you try to join a Windows Vista-based client computer to a top level domain (TLD) that has a purely numeric suffix, the Windows Vista-based client computer cannot join the domain. Additionally, you receive the following error message:

Computer Name/Domain Changes
An Active Directory Domain Controller for the domain could not be contacted. Ensure that the domain name is typed correctly. If the name is correct, click Details for troubleshooting information.

Note: An example of a purely numeric suffix is “contoso.2003.”

When you click Details, you receive the following error message:

An error occurred when DNS was queried for the service location (SRV) resource record used to locate an Active Directory Domain Controller of the domain domain name.

The error was: “The filename, directory name, or volume label syntax is incorrect.”

(error code 0×0000007B ERROR_INVALID_NAME)

The query was for the SRV record for _ldap._tcp.dc._msdcs.domain name.com

If you try to join the domain by using the NetBIOS name of the domain, you are prompted for domain credentials. In this case, the client computer still cannot join the domain. Additionally, you receive the following error message:

The following error occurred attempting to join the domain NetBIOS name of the domain Logon failure: unknown username or bad password.

Consider the following scenario. You develop a Windows Filtering Platform (WFP) driver. You install the WFP driver on a Windows Vista-based computer. In this scenario, some applications and services appear to stop responding for 15 seconds when a Domain Name System (DNS) lookup occurs. This problem occurs if the applications or the services use the DNS function.

When you try to activate Windows Vista, you may receive an error message that resembles the following:

Activation Error: Code 0×8007232b DNS Name does not exist

This problem may occur if you use volume-licensed media to install Windows Vista.

When you try to activate Windows Vista Enterprise or Windows Vista Business, you may receive an error message that resembles the following:

Activation Error: Code 0×8007232b
DNS Name does not exist

This issue may occur if you use volume-licensed media to install Windows Vista Enterprise or Windows Vista Business.

After you use Windows Vista to change the name of a computer, other computers can continue to access the computer by using the previous name of the computer.

When this issue occurs, the following conditions are true:

• If you clear the Domain Name System (DNS) cache by using the ipconfig command together with the /flushdns switch, this issue still occurs.
• If you change the network adapter at the same time that you change the name of the computer, this issue does not occur.
