SYMPTOMS

On a Windows Vista-based computer, the DNS client incorrectly creates a negative DNS cache entry for the NetBIOS name of a remote host. This problem occurs when the client computer is configured to use multiple DNS suffixes. When this problem occurs, you may experience the following symptoms:
  • The Windows Vista-based computer cannot access the remote host by using the NetBIOS name.
  • The NetBIOS name of the remote host cannot be resolved as expected. However, the fully qualified domain name (FQDN) of the remote host can be resolved correctly.
  • If you run the ipconfig /displaydns command to display the content of the DNS resolver cache, the command output indicates that a negative DNS cache entry was created for the NetBIOS name of the remote host.
  • This problem disappears after you run the ipconfig /flushdns command on the computer. However, the next time that the remote host name is resolved, the incorrect negative DNS cache entry appears again.
A typical scenario of this problem occurs when you enable automatic enrollment for certificates in an Active Directory domain environment. This problem causes automatic enrollment to occasionally fail on the Windows Vista-based client computer. Additionally, the following event is logged in the Application log on the client computer:

Event Type: Error
Event Source: AutoEnrollment
Event Category: None
Event ID: 13
Date: Date
Time: Time
User: N/A
Computer: Computer
Description:
Automatic certificate enrollment for Local system failed to enroll the CertType certificate from CA-name (The RPC server is unavailable. 0x800706ba (WIN32: 1722)).

CAUSE

This problem occurs because an error occurs in the DNS client if the DNS suffix of the client computer differs from the DNS suffix of the remote host.

WORKAROUND

To work around this problem, add an entry for the remote host to the Hosts file on the client computer. The Hosts file is located in the following folder:
%windir%\System32\Drivers\Etc
For more information about the Hosts file, visit the following Microsoft Web site:
http://technet.microsoft.com/en-us/library/bb727005.aspx
For more information about how to modify the Hosts file in Windows Vista, click the following article number to view the article in the Microsoft Knowledge Base:
923947 You cannot modify the Hosts file or the Lmhosts file in Windows Vista

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Windows Vista Service Pack 1.

MORE INFORMATION

The following details refer to the issue with certificate enrollment.

Windows Vista uses Task Scheduler (Taskeng.exe) to obtain the new certificate from the CA server by using a remote procedure call (RPC) connection. To create the RPC connection, the system must resolve the CA server name to an IP address. If the DNS suffix of the client computer differs from the DNS suffix of the CA server, the system may create a negative cache entry for the NetBIOS name of the CA server. In this situation, the client computer cannot contact the CA server because the system cannot resolve the CA server name.

To enable automatic certificate enrollment, follow these steps:
  1. Create a computer certificate template.
  2. Configure the Autoenrollment Settings Group Policy setting to Enroll certificates automatically.
