Hi Carlos, The algorithm used is this:
- If the KCC detects that a replication partner fails to respond to a replication request 1 time (inter site) then a timer is started. AND - If the partner fails to respond to subsequent attempts and the timer reaches 2 hours, then the KCC chooses another replication partner. I want the KCC to use a shorter time period than 2 hours before it determines that the partner has failed. I propose 30 mins. Does that now make more sense? Do I understand the algorithm correctly? neil -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Carlos Magalhaes Sent: 19 May 2006 11:16 To: [email protected] Subject: Re: [ActiveDir] Optimising the KCC and detecting DC failures My first question would be, why are you wanting to change the interval in the first place, do you suspect that your DCs are failing at a more frequent interval?
