Cause

This issue occurs when:
 
  1. Automatic Root Updates component is constantly trying to contact Windows Update to see if an update is available.

    Note: This can affect servers that are not connected to the internet or have trouble in contacting Windows Update.

  2. Composer server is unable to contact Windows Update or the Connection server is able to contact Windows update.

Note: The Automatic Root Certificates Update component is designed to automatically check the list of trusted authorities on the Microsoft Windows Update Web site. Specifically, there is a list of trusted root certification authorities (CAs) stored on the local computer. When an application is presented with a certificate issued by a CA, it will check the local copy of the trusted root CA list. If the certificate is not in the list, the Automatic Root Certificates Update component will contact the Microsoft Windows Update Web site to see if an update is available.

Resolution

To resolve this issue, disable the Automatic Root Certificates Update on the affected servers.

To disable the Automatic Root Certificates Update on the affected servers:

Note: To perform this you must be a member of the local Administrators group, or you must have been delegated the appropriate authority.
 
  1. Click Start > Run, type gpedit.msc, and click OK. The User Account Control dialog box opens.
  2. Confirm the action it displays and click Continue.
  3. Navigate to Administrative Templates > System > Internet Communication Management > Internet Communication settings.
  4. Open the Turn off Automatic Root Certificates Update and click enabled.
  5. Click OK.
  6. Close the Local Group Policy Editor.

    Note: You can use Group Policy to set policy settings that apply across a given site, domain, or organizational unit in Active Directory Domain Services.
