Active Directory Child Domain Configuration / User Authentication

Hi,

Windows 2003 R2 AD

I have corp.local and I created city1.corp.local and city2.corp.local (each child domain are interconnected to the corp.local by site to site VPN.

At the corp.local level we have :
Exchange server
An Accounting Terminal Server

I want to improve the login process into the corp Terminal Server for Child Domain user. Right now the user can successfully log on to the terminal server, (city1\user) but the total login process can take up to 2 min.

I added a child domain controller (city1) in the corp lan. But, this seems to stay slow. How can I get my Child domain User to authenticate fast to the Terminal Server.

I'm looking to Add Site in the Site and Service, but I never played much with it except for testing purposes. Should I go this path or there is a more easy way to do it.


FYI : city1 and city2 are managed independly by local administrator (I'm working for a WorldWide Company.

Thanks,

LVL 1

You HAVE TO have AD Sites and Services properly configured. That is the correct and only way to make sure that you talk to the closest server for a variety of things including AD authentication.

By any chance do your users have user profiles assigned? When logging onto a terminal server it may take a while as the users desktop/my documents and other files in the profile is loaded.  In the past I have bypassed this by using a group policy applied to the terminal server in which I disabled the user profile from loading. I believe these two GPO settings may be useful.

Hi

Thanks for your input. I force a group policy loopback on the terminal to avoid those errors. My problem i want to understand why my child dc in my Corp Lan doesn't seems to improve the login process. Any idea ?

Hi bmdgi. kevinhsieh is correct, you must configure a new site for the location in AD. Here's how to do it:
http://technet.microsoft.com/en-us/library/cc781496%28WS.10%29.aspx. AD will automatically create a 'Default Site-Link' used to schedule replication. You may want to do a little research to create or modify the site-link to fit your needs. Good luck!
