We are running a single domain environment with 3 locations

* Head Ofice

* Branch1

* Branch2

* Branch3

Head Office has the DC1 (global catalog) with all FSMO roles and an additional DC2 (not a GC).

Branch 1, 2 & 3 each has an additional domain controller (wich are also Global Catalog holders) that is suppose to provide user logn services to their users respectively.

All these branch connec to the Head Office via 512Kbps ADSL link.

My question .. If all my FSMO roles are on the DC1 at the head office, then who is providing the logon servics to the branch users.?? DC1 at head office or the additional DC at the branch. ?

secondly... if the links between the branch and head office breakes for 3 - 4 days ?? what is the impact on the branch users ? will the additional DC at the branch serve their login requests ????

thirdly.. should my replication be between each DC to all the other 4 DCs on the entire network ??

ie. Branch1 DC replicates to head office DC1, DC2, branch2 DC and branch3 DC..... similarly branch 2 DC replicates to the other 4 DCs.. sort of like a fully meshed network replication .... thats what we have going on right now.

Or should it be that the Branch DCs replicate to the head office DCs only.. ?? like a centralized update location ??

so if Branch 1 DC replicates to Head office DC1 &DC2 , in return the head office DC1 & DC2 replicates the updates to DCs at Branch2 and Branch 3.

Can anyone out ther help me on this ??

The "Discussion" forum is for matters of general discussion, not specific problems in search of a solution.

Post problems such as this to the "Question" forum, rather than the "Discussion" forum. There are those who specifically seek out problems in need of a solution, and that's where they go to look for such.

Additionally there are the benefits that:

1) The "Questions" forum provides for your feedback, by way of your being able to mark "helpful" responses as such. This does not necessarily mean that a given response contained the complete solution to your problem, but only that it served to guide you toward it. This is intended to serve as an aid to those who may in the future have a problem similar to yours, so that they might have a ready source of reference available, thereby perhaps obviating the need for them to repeat questions previously asked and answered.

2) The revised TR makes it quite difficult to find both "Discussions" and "Questions" that have not had a fairly recent post, owing to some functions comingling them in the listings. By keeping each type in their respective forums, it is easier for all to find what they are looking for.

hi

if u wanna save time for each user to authenticated by the main DC
u can create stub zones for each site that is latest in win2003 than secondary domain.

for the branch user nothing happens as such bur your Dc from head office may suffer a lot if they stop stub zone without telling to ur branch
