w32time: The computer did not resync because no time data was available

Question

I am using Windows Time Service to synchronize the time between two machines in a network. The network is isolated and it doesn't have internet connectivity. I configure one of the machines in the network as the server and the other as the client.

The Server configuration w32tm /query /configuration is as follows. The NTPServer bit is enabled in the machine.

[Configuration]

AnnounceFlags: 10 (Local)

You can see NtpServer: [172.19.36.138],0x8 (Local) above which is pointing to the Server that I have configured. I am able to ping between the two machines.

If I try to run w32tm /resync from client it says

Sending resync command to local computer
The computer did not resync because no time data was available.

Why is this happening and How can I fix it.?

Answer 1

1. Reboot the time service

   net stop w32time
   net start w32time
   

2. Tell the time sync service to use the changes

   w32tm /config /update
   

3. Reset the local computer's time against the time server

   w32tm /resync /rediscover
   

The last command will force redetection of network resourced. Note: Resync succeeds even though the error message below appears.

The computer did not resync because no time data was available.

p.s. Please also check whether your firewall allows the ports needed by the time service.

Answer 2

The easiest solution is the installation of the pool.ntp.org.

The installation of the pool.ntp.org time server is recommended by the manual by the following command :

w32tm /config /update /manualpeerlist:"0.pool.ntp.org,0x8 1.pool.ntp.org,0x8 2.pool.ntp.org,0x8 3.pool.ntp.org,0x8" /syncfromflags:MANUAL

The additional information you can find here: https://support.ntp.org/bin/view/Support/WindowsTimeService

Answer 3

FYI please notice on your server:

VMICTimeProvider (Local)
DllName: C:\Windows\System32\vmictimeprovider.dll (Local)
Enabled: 1 (Local)

This means it is a VM getting its time from it's host, NOT the domain on NT5DS like you may think it is.

Also on your client check if those brackets [ ] are correct, I'm using a DNS name and seen no brackets, not sure but that may not be the correct syntax.
