Symptoms

When you start a computer that is running Windows Vista Service Pack 2 (SP2) or Windows Server 2008 Service Pack (SP2), the computer stops responding and appears to hang at the "Applying User Settings" or "Applying Computer Settings" stage of the logon process.

You may experience that the "network connections" folder is empty. Additionally, the following services may not start at startup.

Note These services are set to the "Automatic" startup type.

  • Print Spooler

  • Terminal Services

  • Server service

  • Remote Registry

  • Windows Management Instrumentation (WMI)

  • Distributed Transaction Coordinator

  • Any services that are related to applications

Note This issue typically occurs after you install a server certificate and then configure Secure Sockets Layer (SSL) on the computer. For example, you install a SSL server certificate in Internet Information Services (IIS) 7.0 and then enable HTTPS on your website to use the certificate.

Cause

This issue occurs because of a deadlock in the Service Control Manager database.

The Service Control Manager tries to start the HTTP.sys service and then puts a lock in place in the Service Control Manager database. Then, HTTP.sys makes a call that requires Cryptographic Services during startup. Then, a request is sent to start Cryptographic Services. However, a lock is already in place in the Service Control Manager database. Therefore, a deadlock occurs.
