RE: NTP Rule for DC doesn't work

Hi

Still searching for a solution to this one.

I can get the ISA to sync externally but I know that's not right - the DC
should be the authoritative time source but I can't get it to talk to an
external ntp server.

I need to get this working or my entire project will grind to a halt so any
advice would be much appreciated...
