SYMPTOMS
You have enabled the Certificate Services service on a Microsoft Windows Server 2003 Service Pack 1 (SP1)-based computer. When you use the Certificates console on a client computer to request a certificate, you receive the following error message:

The wizard cannot be started because of one or more of the following conditions:

- There are no trusted certification authorities (CAs) available.

- You do not have the permissions to request certificates from the available CAs.

- The available CAs issue certificates for which you do not have permissions.

Additionally, events are logged in the Application log on the server that hosts the certification authority (CA). These events resemble the following: Event Type: Warning

<div class="cause_section">

CAUSE
Windows Server 2003 SP1 introduces some enhanced default security settings for the DCOM protocol. Specifically, Windows Server 2003 SP1 introduces rights that give an administrator independent control over local and remote permissions for the following tasks:
 * Starting Component Object Model (COM) servers
 * Activating COM server settings
 * Accessing COM servers

The Windows Server 2003 SP1 installation process creates a new CERTSVC_DCOM_ACCESS security group. After the installation of Windows Server 2003 SP1, this new security group should have appropriate DCOM Access permissions and DCOM Launch and Activation permissions. By default, the Domain Users global group and the Domain Computers global group reside in the CERTSVC_DCOM_ACCESS group. If the Certificate Services service is running on a domain controller, the CERTSVC_DCOM_ACCESS group is created as a Domain Local group. Additionally, the Enterprise Domain Controllers group should be a member of the CERTSVC_DCOM_ACCESS group. This problem occurs if the membership of the CERTSVC_DCOM_ACCESS group is configured incorrectly.

<div class="resolution_section">

RESOLUTION
To resolve the problem, follow these steps: <ol> Verify that the CERTSVC_DCOM_ACCESS group exists in the domain that hosts the certification authority. This group is in the CN=Users container. To do this, follow these steps: <ol style="list-style-type: lower-alpha;"> Click Start, click Run, type Dsa.msc, and then click OK.</li> In the left pane, click the Users container.</li> Verify that the CERTSVC_DCOM_ACCESS group is in the right pane. If the CERTSVC_DCOM_ACCESS group is not in the right pane, go to step 4.</li></ol> </li> Verify that the CERTSVC_DCOM_ACCESS group includes the following member groups:  Domain Users</li> Domain Computers</li></ul>

If these member groups do not exist in the CERTSVC_DCOM_ACCESS group, go to step 4.

Note If users or computers in other domains need to enroll against the certification authority, you must also add those users and computers to the CERTSVC_DCOM_ACCESS group. If the current problem occurs on a domain controller, you must also add the Enterprise Domain Controllers group to the CERTSVC_DCOM_ACCESS group. By default, domain controllers are not members of the Domain Computers global group. Therefore, domain controllers do not have sufficient DCOM permissions.</li> Verify that the CERTSVC_DCOM_ACCESS group has the appropriate DCOM Access permissions and DCOM Launch and Activation permissions on the computer that hosts the certification authority. <ol style="list-style-type: lower-alpha;"> Click Start, point to Program, point to Administrative Tools, and then click Component Services.</li> Expand the Component Services node.</li> Expand the Computers node.</li> Right-click the My Computer node, and then click Properties.</li> Click the COM Security tab.</li> <li>Under Access Permission, click Edit Limits.</li> <li>Verify that the CERTSVC_DCOM_ACCESS group has Allow Local Access and Allow Remote Access permissions, and then click Cancel.</li> <li>Under Launch and Activation Permissions, click Edit Limits.</li> <li>Verify that the CERTSVC_DCOM_ACCESS group has Allow Local Activation and Allow Remote Activation permissions, and then click Cancel.</li> <li>Click Cancel, and then close the Component Services console.</li></ol> </li> <li>Settings may be incorrect if any one of the following conditions is true: <ul> <li>The CERTSVC_DCOM_ACCESS group does not exist.</li> <li>The default membership of the CERTSVC_DCOM_ACCESS group is incorrect.</li> <li>The CERTSVC_DCOM_ACCESS group does not have the correct permissions.</li></ul>

If any one setting is incorrect, run the following commands at a command prompt. Press ENTER after each command.

certutil -setreg SetupStatus -SETUP_DCOM_SECURITY_UPDATED_FLAG

net stop certsvc

net start certsvc

</li> <li>Repeat steps 1 through 3 to verify that all the settings are correct.

Note If the changes affect the group membership of the certification authority server, you must restart the server for the changes to take effect.</li></ol>
