Problem with verifying system clock
If there is a problem with using lmxresetsystemclock.exe to synchronize you local system's clock with a remote time server, you may see the following error:
LM-X Error: Could not verify system clock due to failed connection with remote time server
To resolve this problem, it is necessary to verify that UDP port 123 (NTP protocol) is not blocked by a firewall.
