I have some Windows PCs. PING and FreeDiskSpace sensors working except SNTP on all of them. I get "The server did not return a valid time (code: PE085)". On Linux machines it works without problems. Is there any workaround on this?

In my case this problem affects only Windows 7 x64. Windows XP x32 works fine.

hello,
are the devices you are adding this sensor to all running an the NTP service? The device you add the senor to has to be an NTP server!

No, it was not running. Nor on Windows 7 nor on Windows XP. Windows XP was working fine though sometimes it was stopping returning NTP values. Start --> Run --> GPedit.msc --> [Enter] --> Local Computer Policy --> Computer Configuration --> Administrative Templates --> System --> Windows Time Service --> Time Providers --> Windows NTP Server --> Enable. Now both Windows XP and Windows 7 are working. Thank you!

After I enabled NTP server my sensor says the server did not return a valid time (code: PE085), I also start the windows time in services.msc
How can I configure this sensor?

- In mostly cases I just try to sync compuers time with the real NTP server. In my case the PRTG core machine and client computers are syncing with the same NTP server.
- If above does not work, I try to modify registry further:
HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Config\AnnounceFlags to "5"
HKLM\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer\Enabled to "1"
HKLM\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\VMICTimeProvider\Enabled to "0"
The last key is not in every Windows distribution and I leave it as it is. Then
Start --> Run --> net stop w32time
Start --> Run --> net start w32time
In one of my cases none of the above solutions helped me and I'm seeking to resolve this problem as well.
