- Description: No valid response has been received from manually configured peer - In my case, I was not able to synchronize the PDC server, which was an NTP server as well, and all other clients were synchronizing their times according to this server.
1. Set all servers in the domain to be synchronized by your PDC.
- nltest /dclist:domain
- for /f "tokens=1, *" %i in (servers.txt) do net time \\%i /setsntp:PDC-NTP-Server /y >> result.txt
The file servers.txt contains a list of your servers.
- net time /domain:domain name /set
2. Modify the registry to set the time server. Go to HKLM\System\CurrentControlSet\Services\lanmanserver\parameters and add a key TimeSource (reg_dword) with a value of 1.
3. This problem may occur when your computer sends synchronization requests by using symmetric active mode. By default, Windows Server 2003 domain controllers are configured as time servers and use symmetric active mode to send synchronization requests. Some NTP servers that do not run Windows respond only to requests that use client mode.
Click Start, click Run, type cmd, and then press Enter. At the command prompt, type the following commands in the order that they are given. After you type each command, press Enter:
• w32tm /config /manualpeerlist:NTP_server_IP_Address, 0x8 syncfromflags:MANUAL
• net stop w32time
• net start w32time
• w32tm /resync
After applying these steps, the problem should be solved.
