Hello, as we asked beofre please post the complete event viewer errors for w32time source. Do you use any kind of GPO for time confiugration settings? Did you reset the time to default and configured it again? Please run the following in an elevated command prompt: net stop w32time w32tm /unregister w32tm /register net start w32time After that is done: w32tm /config /manualpeerlist:PEERS /syncfromflags:manual /reliable:yes /update Please set for PEERS the time source as listed above, either with its ip address or DNS name. If more then one is needed separate them with a space in between and don't forget the quotes: "time.domain.com time1.domain.com" Internet Time servers you can find here: http://www.pool.ntp.org/ And choose ANOTHER time source as the one you are using now.Best regards Meinolf Weber MVP, MCP, MCTS Microsoft MVP - Directory Services My Blog: http://msmvps.com/blogs/mweber/ Disclaimer: This posting is provided AS IS with no warranties or guarantees and confers no rights.
