  • Article

Applies To: Windows Server 2008

Certification authorities (CAs) need adequate system resources and operating system components to function. If a server has insufficient memory or hard disk space, or if operating system components become unavailable, attempts to start Active Directory Certificate Services (AD CS) can fail.
