Hello, please post an unedited ipconfig /all from the DC and the problem server. Is there any firewall running that blocks port 123 UDP? Also run on the member server: w32tm /config /syncfromflags:domhier /update After that you have to run: net stop w32time net start w32time Then check the event viewer again.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
