After you enable automatic enrollment for certificates in an Active Directory domain environment, automatic enrollment occasionally fails on a Windows Vista-based client computer. Therefore, the client computer cannot obtain certificates automatically.

When this problem occurs, an event that resembles the following is logged in the Application log on the client computer:

Event Type: Error
Event Source: AutoEnrollment
Event Category: None
Event ID: 13
Date: Date

Description:
Automatic certificate enrollment for Local system failed to enroll the CertType certificate from CA-name (The RPC server is unavailable. 0x800706ba (WIN32: 1722)).

If you run the ipconfig /displaydns command on the client computer 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 certification authority (CA) server.

This problem occurs when the client computer is configured to use multiple DNS suffixes.

You install Windows Vista and then restart the computer. An event that resembles the following is logged in the Application event log on a Windows Vista-based computer:

In Windows Vista, if an application uses the ReadEventLogA function to read a Unicode string from the event log, the string appears as a question mark.

A Warning event message that resembles the following may be logged in the Windows Vista event log:

The description for Event ID 129 from source iScsiPrt cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
The message has no description.

This message is logged when the Vista initiator sends an iSCSI Task Management command to the target device, and the device (\Device\ScsiPort0) does not respond within the time-out period.

In Windows Vista, the event log is not saved when you click Save and Clear after you click Clear Log in Event Viewer.
