Description: This is the new interface called from winlogon/userenv to generate planning RSOP data. The dll name and procedure name are registered to winlogon under GpExtensions.
This routine simulates a SCE group policy template to the current system. The template can be in domain level, OU level, or user level.
The input argument contains info about the GPOs to be simulated and a namespace pointer to log the RSOP data.
This interface shouldn't be called for user policy.
Arguments:
dwFlags - the GPO Info flags GPO_INFO_FLAG_MACHINE GPO_INFO_FLAG_SLOWLINK GPO_INFO_FLAG_BACKGROUND GPO_INFO_FLAG_VERBOSE GPO_INFO_FLAG_NOCHANGES
pwszSite - unused now
pComputerTarget - RSOP machine structure having GPOList, token (unused now) etc.
pUserTarget - RSOP user structure having GPOList, token (unused now) etc.
pbAbort - processing of GPO should be aborted if this is set to TRUE (in case of system shutdown or user log off)

Description:
This routine is called for both planning and diagnosis modes. In this routine, all GPOs are copied locally into a cache for use by the logging routines and/or configuration routines after this routine.
SceProcessAfterRSOPLogging is a sister function that is called for diagnosis mode only.
This interface shouldn't be called for user policy but within the routine, a checking is still made to make sure that user level policies is not processed. For domain or OU level policies, This routine categories policy: 1) policy must be enforced before user logon (security policy and user rights), 2) policy can be applied after user logon (for example, file security). For diagnosis mode, The 2nd category is applied asynchronously (in a separate thread).
Arguments:
dwFlags - the GPO Info flags GPO_INFO_FLAG_MACHINE GPO_INFO_FLAG_SLOWLINK GPO_INFO_FLAG_BACKGROUND GPO_INFO_FLAG_VERBOSE GPO_INFO_FLAG_NOCHANGES
hUserToken - the user token for which the user policy should be applied if it's the machine policy, hUserToken refers to system
hKeyRoot - the root for the policy in registry
pDeletedGPOList - all deleted GPOs to process
pChangedGPOList - all GPOs that are either changed or not changed
pHandle - for asynchronous processing
pbAbort - processing of GPO should be aborted if this is set to TRUE (in case of system shutdown or user log off)
pStatusCallback - Callback function for displaying status messages
Return Value:
Win32 error ERROR_SUCCESS E_PENDING if asynchonous processing other errors
Note, if error is returned, the previous cached GPO list will be used for next propagation (because it didn't succeed this time).

Description: This is a interface called from winlogon/userenv to process GPOs. The dll name and procedure name are registered to winlogon under GpExtensions.
This routine applies a EFS recovery policy to the current system. The EFS recovery policy is stored in registry as EfsBlob and will be loaded by the registry extension into hKeyRoot. So this extension requires that registry.pol must be loaded successfully by the registry extension.
This interface can be called during system boot, or every GPFrequency hours after logon. The input argument contains info for where this interface is called and under which context (user, or machine) this interface is called.
This interface shouldn't be called for user policy but within the routine, a checking is still made to make sure that user level policies is not processed.
Arguments:
dwFlags - the GPO Info flags GPO_INFO_FLAG_MACHINE GPO_INFO_FLAG_SLOWLINK GPO_INFO_FLAG_BACKGROUND GPO_INFO_FLAG_VERBOSE GPO_INFO_FLAG_NOCHANGES
hUserToken - the user token for which the user policy should be applied if it's the machine policy, hUserToken refers to system
hKeyRoot - the root for the policy in registry
pDeletedGPOList - all deleted GPOs to process
pChangedGPOList - all GPOs that are either changed or not changed
pHandle - for asynchronous processing
pbAbort - processing of GPO should be aborted if this is set to TRUE (in case of system shutdown or user log off)
pStatusCallback - Callback function for displaying status messages
Return Value:
Win32 error ERROR_SUCCESS other errors
Note, if error is returned, the previous cached GPO list will be used for next propagation (because it didn't succeed this time).
