Can the SNTP Service coexist with the W32Time service?
It is possible to start W32Time without conflict but the synchronization functions of W32Time must be turned off. This avoids problems with applications that require the W32Time service (ie. Cluster Server or Domain Controllers). The synchronization functions continue to be implemented by the SNTP Service. Normally the Windows Time service startup can be disabled when SNTP Service is running except if the system is running Cluster Service or is a Domain Controller. The SNTP Service will automatically adjust the appropriate W32Time registry entries at install time if it detects that Cluster Services are present. After installing on a Domain Controller (DC) you can use the SNTP Service control panel applet to disable W32Time time synchronization functions. In either case you should disable the SNTP Service server function. After doing this you must restart both the W32Time service and the SNTP Service. Do not use the NET TIME /setsntp command on a system that is running both the SNTP Ser
