I am looking for second opinion on our AD design. I was thinking simpler was better. I currently am looking at doing single forest, single domain.
We recently merged with another firm and now have 8 total sites. 3 main with 100-300 users and 5MB WAN connections. 5 branch locations with 5-50 users and T1 connectivity to main site. Each main site has 2 DCS and each branch at least one.
Currently, we represent about half the users and have a single domain. The other users have a main domain and child domains and Exchange servers for each site. There are no significant security, legal or password differences between our sites and we hope to centrally manage (though we may delegate control to a local admin's OU). I think our bandwidth will be adequate for site to site replication as we do not rapidly change personnel.
Any other thoughts or reasons why I would NOT want to stay single domain with an OU structure based on site.
Thanks for any suggestions you can offer.
