Module Name:

|
|
FixServiceStartupCircularDependency.cpp
|
|
|
|
Abstract:
|
|
|
|
Hooks the call to CreateServiceA and changes the start parameter for
|
|
only the service passed in COMMAND_LINE from SERVICE_AUTO_START to
|
|
SERVICE_SYSTEM_START. This eliminates a circular dependency during
|
|
boot up which results in XP taking 15 to 20 minutes to boot.
|
|
|
|
Notes:
|
|
|
|
This is a general purpose shim. Pass the service name in the command
|
|
line. It tests if the startup type for that service is SERVICE_AUTO_START
|
|
and if so changes it to SERVICE_SYSTEM_START.

line to pass in the service name.
