On Windows 2003 the HTTPSSL service (the service that implements SSL) runs in the lsass.exe process. If you ever are interested in running the HTTPSSL service in a svchost.exe process instead of the default lsass.exe here is how you do it.
To configure the HTTPFilter service to run in its own svchost, we have to modify the ImagePath value for the service entry in the registry.
ImagePath C:WINDOWSsystem32svchost.exe -k HTTPFilter
Restart the HTTP.SYS driver
net stop HTTP /y
net start HTTP
This will make the HTTPFilter service to run under a svchost.exe instead of the lsass.exe
Ensure you backup the registry key before making the changes.
