Install an MS agent

  • Windows

  • Windows ( CLI )

  1. Run the bootstrap application.

    The bootstrap application will download the Windows Installer package files (MSI) from https://dist.sectigo.com as necessary. If you’re using an HTTP proxy, ensure that your OS proxy settings have been configured to allow access to https://dist.sectigo.com.

  2. Read the EULA, select I agree to the license terms and conditions, and click Install.

  3. Click Next.

  4. Read the EULA, select I accept the terms in the License Agreement, and click Next.

  5. (Optional) Specify an install location.

  6. (Optional) Select the Proxy MS Enrollment Protocols to SCM feature.

  7. Click Next, and paste the agent install token.

    If needed, you can retrieve the installation token from the Edit MS Agent dialog for your agent. This token is no longer available once the agent connects to SCM for the first time.

  8. Click Next.

  9. (Optional) Select Use Proxy and enter your proxy details based on the information provided in the following table.

    Field Description

    Proxy Host

    The hostname or IP address of your proxy server

    Proxy Port

    The port number used by your proxy server

    Proxy User

    The username for accessing the proxy server if configured to use credentials

  10. Click Next.

  11. (Optional) Disable Enable Auto Update if you do not want the agent to automatically update to new versions.

The agent should now be listed on the MS Agents page with a status of Connected.

MS Agent Connected
To be notified in the event that an agent is disconnected, add the MS Agent Disconnected notification.

  1. Open the Windows command prompt.

  2. In the command line, navigate to the download location of the bootstrap application.

  3. Modify the installation command as needed.

    .\Sectigo_MS_Agent.exe /i /q PROPERTY_AUTOUPDATE=1 PROPERTY_TOKEN= PROPERTY_CA_PROXY= PROPERTY_USE_PROXY= PROPERTY_PROXY_PAC_URL= PROPERTY_PROXY_HOST= PROPERTY_PROXY_PORT= PROPERTY_PROXY_USER= PROPERTY_PROXY_PASSWORD=

MS agent service commands

  • Proxy service

  • Discovery service

When an MS agent is installed with Proxy MS Enrollment Protocols to SCM selected, the service commands are as follows:

Command Description

Start

Start an MS agent:

sc start CertSvc

Stop

Stop an MS agent:

sc stop CertSvc

Query

Query the status of an MS agent:

sc query CertSvc

When an MS agent is installed for discovery only (without Proxy MS Enrollment Protocols to SCM selected), the service commands are as follows:

Command Description

Start

Start an MS agent:

sc start ComodoMSAgent

Stop

Stop an MS agent:

sc stop ComodoMSAgent

Query

Query the status of an MS agent:

sc query ComodoMSAgent

Custom Java Runtime Environments

In some rare circumstances the default Java Runtime Sectigo packages included with the MS agent might need to be customized. For example, this can happen if an HTTP proxy is using privately trusted certificates or requires authentication schemes that aren’t enabled by default.

  1. Open the Registry Editor application.

  2. Navigate to HKEY_Local_Machine  Software  Comodo  CCM.

  3. Right-click on CCM and select New  Multi-String Value.

  4. Rename the new registry value to be JavaOpts.

  5. Modify the Value data for JavaOpts using the information provided in the following table.

    JVM Parameter Description

    -Djavax.net.ssl.trustStore=path_to_keystore.jks

    Replaces the truststore used by the JVM when trusting SSL certificates

    Can be used if HTTP proxy uses a privately trusted certificate instead of needing to modify the JVMs truststore (cacerts)

    -Djdk.http.auth.proxying.disabledSchemes=""

    Reenables all authentication schemes when connecting to HTTP proxy

    -Djdk.http.auth.tunneling.disabledSchemes=""

    Reenables all authentication schemes when connecting to HTTP proxy using TLS

  6. Click OK.

Configure LDAPS communication with MS AD

Enable LDAPS communication between the MS Agent and MS AD as follows:

  1. Obtain an SSL certificate.

    The SSL certificate must comply with the requirements outlined by Microsoft for an LDAPS certificate. These requirements are subject to change by Microsoft at any time without notice.

    To view the current requirements, see Enable LDAP over SSL with a third-party certification authority.

  2. Run regedit.

  3. Navigate to HKEY_LOCAL_MACHINE  SOFTWARE  COMODO  CCM.

  4. Create a value of the type REG_DWORD = UseLDAPS.

  5. Specify a Data value of 0 if using LDAP, or 1 if using LDAPS.

    Since LDAPS communication imposes additional requirements, LDAP is the default communication protocol.

  6. Restart the agent using the certsrv.mcs snap-in.
