Hi Rania, One forest with one domain should do it for you and make all DCs a GC The site and replication topology is used: * By DCs so they know with which DC to replicate with within a site and between sites * By clients/servers to find the "nearest" DC for authentication, GPOs, etc. Now we need to define "nearest".... The clients get the nearest DC by querying DNS. If the clients don't know what site they are in (mostly when joining) they ask DNS: "give me a DC for domain X". If they have discovered the site they are in they ask DNS: "give me a DC for domain X in site Y" In your situation having 2 location separated by a wireless connection you have the following possibilities: (1) Create 1 overal site for both locations and assign the subnets of the locations to that site (2) Create 2 sites, one for each location and assign the subnets of each location to the corresponding site (1) The answer for the query for "give me a DC for domain X" and "give me a DC for domain X in site Y" is the same. Assuming you have DCs at both locations a client in location A can be serviced by a DC in location A and B. So authentication across the wireless connection is a possibility! I don't think you want that (2) Assuming again you have DCs at both locations, the query for "give me a DC for domain X" and "give me a DC for domain X in site Y" will have different answers. In this case the client will be authenticated (and etc.) by a DC local to its own site. A best practice and highly recommended is to have AT LEAST 2 DCs for each domain and also to backup AT LEAST 2 DCs for each domain. In your case it is unknown to us how many users you have in your organization (at both location) so it is difficult to say how many DCs each location should get. * If you always need authentication within a site in the situation a DC might crash use 2 DCs for each location. Might be rather expensive is the organization is small * If you have a location with many users and a location with few users you could install 2 DCs at the "many users location" and 1 DC at the "few users location". If one of the DCs in the "many users location" drops dead you still have the second DC to authenticate locally. If the DC in the "few users location" drops dead you will need to authenticate across the wireless connection * If both locations have not that many users and you want to spend that much money on DCs, you could install just 1 DC at each location where each DC must be able to service user/clients/servers in both locations if one of the DCs drops dead. >From what you have told us and what I have read I think the following would be >OK: * 1 DC at each location * 1 AD site for each location * Assign subnets of each location to its corresponding AD site * Use the default IP site link and assign both sites to it and configure the site link accordingly for replication between the sites (cost, schedule, interval) * Combine DC, DNS, WINS, DHCP on one server and if needed wanted setup DHCP redundant using the 80/20 rule I hope this takes away you confusion Cheers, Jorge

The head office have one single Network with this Range of IP-Address ( 70.0.0.X / 255.255.255.0 ) . We have Wireless -Point-To-Point Between the 2 locations . The Privare office have also one single Network with the same range of IP-Address in the Head office which is ( 70.0.0.X / 255.255.255.0 ). All of them is under Workgroup, and no domains at all . ---------------------- ---------------------------------------------------------------------- what we need , is to create domain and to provide users with the authentication from the domain by using user name & Password. ----------------------------- My question is here, i am really get confused, what should i follow :- 1- Should i follow Single Site for the 2 locations & each site will represented by subnet , so i will have 2 subnets in one site ? Or 2- should i follw Multiple Site with one subnet at least in each site, and each site will represent the location it self ? i really get confused. as i know the site is used for the Replication , so i want to simple the replication it self. CAN ANY ONE GUIDE ME TO THE BEST OF IT. Best Regards, RANIA SAMEER.
