Yes, I probably caught 10.0.7.6 restarting ntp as I was trying to determine if there was some new incompatability or I changed some firewall rule, so I may have inadvertently blocked it. I apologise for complicating the original situation/post. Typically 10.0.7.6 is rebooted when the UPS needs new batteries, acting as firewall and time server. -- *** *NOTICE *This email and any attachments may contain legally privileged or confidential information and may be protected by copyright.
