3.2.1.2.1 NTP Client Provider Elements
The following elements are defined for each NTP client time provider found in the time provider list. These elements are read-only.
CrossSiteSyncFlags: An integer indicating the combination of flags that determines how the time service selects its time source inside a domain.<26> The value MUST be one of the following.
-
Value
Meaning
NCCSS_None
0x00000000
The time service SHOULD NOT select a time source outside the same site as the machine.
NCCSS_PdcOnly
0x00000001
The time service SHOULD select only the primary domain controller (PDC) as its time source.
NCCSS_All
0x00000002
The time service is allowed to select a time source inside or outside the same site as the machine.
-
All other values are reserved for future use.
CompatibilityFlags: An integer that indicates the combination of flags that determines how the time service validates and accepts a response from its time source. The value MUST be a bitwise OR of zero or more of the following flags.
-
Value
Meaning
DISPERSION_INVALID
0x00000001
Ignore invalid dispersion check.
IGNORE_FUTURE_REFTIMESTAMP
0x00000002
Ignore reference time-stamp check.
AUTODETECT_WIN2K
0x80000000
Ignore the root dispersion.
AUTODETECT_WIN2K_STAGE2
0x40000000
Ignore the root dispersion by resending a request with a root dispersion of 0xAAAAAAAA.
-
All other values are reserved for future use.
NTPEventLogFlags: An integer that indicates the combination of flags that determines how the time provider logs events into an event log. The value MUST be a bitwise OR of zero or more of the following flags.
-
Value
Meaning
NCELF_LogReachabilityChanges
0x00000001
Log an event when reachability for a time source has changed.
NCELF_LogIfSampleHasLargeSkew
0x00000002
Log an event when a large time sample skew is detected.
NCELF_LogClientRequestError
0x00000004
Log an event when the time provider fails to receive its response.
All other values are reserved for future use.
LargeSampleSkew: An integer that indicates the large time sample skew threshold, in seconds. If a time sample has a difference from the time of the local clock that is more than this value, it MUST be considered to be a sample with large skew.
