I had to become a member of this forum - just to say a big THANKS to all that participated on this thread... My problem was my PDCe continually bouncing back "The computer did not resync because no time data was available." I spent literally hours scouring the web for solutions, finding great amounts of valuable information but this particular thread, I believe is the most helpful! My problem came down to the solution that annab2, so THANK YOU VERY MUCH - I sincerely appreciate everyone's time spent (no pun intended). I have one question to add if I may... Our secondary DC is returning a NTP: error ERROR_TIMEOUT - no response from server in xxxxms. I have checked the registry settings to ensure that those pesky GPO inherited registry settings are removed, and checked that the DC is set in its default state, so it supposedly will sync automatically with the PDCe. Running a w32tm /monitor command returns C:\>w32tm /monitor cde01.domainname.local *** PDC *** [xx.x.2.1]: ICMP: 589ms delay. NTP: +0.0000000s offset from cde01.domainname.local RefID: reptile.digitalriver.com.au [121.54.129.52] abc01.domainname.local [xx.x.1.4]: ICMP: 0ms delay. NTP: error ERROR_TIMEOUT - no response from server in 1000ms Appreciate any help on this related subject... thanks. Cheers tropolite
