To configure the time service on a domain member to synchronize time N times per day:

1. Use your Registry Editor to navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters.

2. Delete the Period Value Name.

3. Add the Period Value Name as a REG_DWORD data type, and set it to the number (N), using the Decimal radix.

4. Set the data value of the GetDcBackoffMaxTimes Value Name, a REG_DWORD data type, to 0.

5. Set the data value of the GetDcBackoffMinutes Value Name, a REG_DWORD data type, to 1.

6. Open a CMD.EXE window.

7. Type the following commands, pressing Enter after each line:

net stop W32Time
net start W32Time
