I am receiving these errors consistently on Windows XP Pro machines on a Windows 2000 server. The 14 error says The time provider NTpClient was unable to find a domain contoller to use as a time source. NTpClient will try again in 120 minutes. The 29 error says The time provider NTpClient is configured to aquire time from one or more time sources, however none of these sources are currently accessable. No attempt to contact a source will be made for 59 minutes. NTpClient has no source of accurate time. Is there a time service on the server that needs to be started? Any help would be appreciated.
