Graham- Since your questions are probably a bit more geared towards DFS behavior, I probably can't personally help much. But here goes: 1. yes, I believe that is the case because when you look at the LDAP queries that go to AD during the initial setup of GP processing, one of them is for the DFS object underlying SYSVOL. 2. I believe that it would be a random list of DCs in the site that is normally returned. Not sure I understand the second part of the question--my understanding of this KB is that it puts the logonserver DC at the top of the DFS referral list just by reordering the list that is returned. 3. Yes, I believe it's a simple matter of try the replica, if it can connect then use it. I could be wrong here however--it may actually ping the DC first but I haven't done a sniffer trace of this. Also, keep in mind that DFS referrals are cached for 180 minutes by default, if I remember correctly.

I assume DFS referral request is sent to the logon server discovered by SRV (not SVC record lookup data) records in the DNS ?? 2. the DFS server responds with a referral list prior to this patch how would a DFS referral list be ordered ? with this patch and configured with 'preferlogondc', what mechanism does the DFS server put the 'logon server' at the top of the list ? 3. how does the client respond to the DFS referral list say in terms of connecting to other servers in the list retry / timeout if not avaialble ?
