Every day at 7h09, I get the same error from Bluecoat Proxy SG:
2010-11-15 07:09:36+01:00CET "NTP: Tried all configured servers. Unable to obtain NTP update due to NTP server errors." 0 90000:1 Mailed ../ntp.cpp:724
If I use the manual update, all is working fine, and the bluecoat update the time every hour without any error, just once a day.
I can't see nothing in the NTP server log.
The ntp server are Windows Server 2008: there is two ntp servers configured.
