A quick post about an IIS 6.0 error "The tracking (workstation) service is not running": Sometimes, after an iisreset and restarting an SSL website, the following error is displayed:

The tracking (workstation) service is not running

To fix this error you need to start restart the SSL service. In PowerShell / cmd.exe, type:

net start httpfilter

This will start the SSL service. Then type iisreset to restart IIS again (if necessary).
