Routine Description:

specified by (HKey, KeyPath) must be moved into the final
registry.
NTFRSAPI_BUR_FLAGS_RESTART - Restart the service. HKey,
KeyPathSizeInBytes, and KeyPath must be NULL.
If NtFrsApiInitializeBackupRestore() was not called the above flags,
then BurFlags must be NTFRSAPI_BUR_FLAGS_NONE and HKey, KeyPathSizeInBytes,
and KeyPath must be NULL.
Arguments:

NULL if BurContext is not for a System or
Active Directory restore or Restart is set.
KeyPathSizeInBytes - Address of of a DWORD specifying the size of

The paths may overlap the replicated directory.
The paths may contain nested entries.

the registry key FilesNotToBackup.
The replicated directory can be found with
NtFrsApiGetBackupRestoreSetDirectory(). The replicated directory
may overlap one or more entries in Paths.

determined.

);
/*++
Routine Description:
The NtFrs service polls the DS occasionally for configuration changes.
This API alters the polling interval and, if the service is not
in the middle of a polling cycle, forces the service to begin a
polling cycle.
The service uses the long interval by default. The short interval
is used after the ds configuration has been successfully
retrieved and the service is now verifying that the configuration
is not in flux. This API can be used to force the service to use
the short interval until a stable configuration has been retrieved.
After which, the service reverts back to the long interval.
The default values for ShortInterval and LongInterval can be
changed by setting the parameters to a non-zero value. If zero,
the current values remain unchanged and a polling cycle is initiated.
Arguments:
ComputerName - Poke the service on this computer. The computer
name can be any RPC-bindable name. Usually, the
NetBIOS or DNS name works just fine. The NetBIOS
name can be found with GetComputerName() or
hostname. The DNS name can be found with
gethostbyname() or ipconfig /all. If NULL, the
service on this computer is contacted. The service
is contacted using Secure RPC.
UseShortInterval - If non-zero, the service switches to the short
interval until a stable configuration is retrieved
from the DS or another call to this API is made.
Otherwise, the service uses the long interval.
LongInterval - Minutes between polls of the DS. The value must fall
between NTFRSAPI_MIN_INTERVAL and NTFRSAPI_MAX_INTERVAL,
inclusive. If 0, the interval is unchanged.
ShortInterval - Minutes between polls of the DS. The value must fall
between NTFRSAPI_MIN_INTERVAL and NTFRSAPI_MAX_INTERVAL,
inclusive. If 0, the interval is unchanged.
Return Value:
Win32 Status

This API returns the values the service uses for polling intervals.
The service uses the long interval by default. The short interval
is used after the ds configuration has been successfully

NtFrsApi_Set_DsPollingIntervalW() is used to force usage of the short
interval until a stable configuration has been retrieved. After which,
the service reverts back to the long interval.
The value returned in Interval is the polling interval currently in
use.
Arguments:
ComputerName - Poke the service on this computer. The computer
name can be any RPC-bindable name. Usually, the
NetBIOS or DNS name works just fine. The NetBIOS
name can be found with GetComputerName() or
