W32Time Clock synchronisation
The normal configuration of the W32time service on Windows 2000 computers is set to synchronise the real time clock with a domain controller. If you have a internet connection you can configure the W32time service to synchronise with an external time service using the NTP (Network Time Protocol).
- HKEY LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
| Entry Name | Data Type | Description |
| LocalNTP | REG_DWORD | 0 or 1, 0= do not start server, 1= Always start server |
| Type | REG_SZ | Nt5DS = default , sync to domain or manually configured,
NTP= Only manually configured source |
| Period | DEG_DWORD or REG_SZ | 65531 "DailySpecialSkew" = once every 45min then once a day
65532 "SpecialSkew" = one every 45min, the every 8 hours(Default) 65533 "Weekly"65534 "Tridaily" = once every 3 days 65535 "BiDaily" = once every 2 days0 = once per day |
| NtpServer | REG_SZ | e.g. "tik.cesnet.cz" |
Force, debug NTP time synchronization:
1) Stop the windows time service:
net stop w32time
2) Test communication with default NTP server:
w32tm -once -test -v
or sync with time server, response should be "RPC to local server returned 0x6b5"
w32tm -s
3) Start the windows time service:
net start w32time
