Re: NTP Synchronization lost in PIX515e

What version is your PIX firewall? and was NTP synchronization working before? Can you also check if there is any failover between the PIX firewalls?

Re: NTP Synchronization lost in PIX515e

Can we also find out what is the NTP source? Has it changed? If it does what is the changes? What is the OS of the NTP source/server?

Have you tried to use other NTP server?
