1/. Yes it is possible to have more than 1 domain. Actually it is highly recommend.

2/. Here - http://www.microsoft.com/windows2000/techinfo/planning/activedirectory/domaincntrl.asp

3/. You want more than one DC for fault tolerance and redundancy. In the event of a DC failure you still have a server that can process logon requests, retain all user information, security policies, logon scripts and computer memberships to name just a very few. So it can still do all this while you repair the other one. Plus if the worst comes to the worst you can still recover it from the DC still functioning.

I got another problem when i connect windows 98 second edition to my windows 2000 domain.

I create one user account using the active directory user and group. the user name is aaa and password is bbb.

So i went to the windows 98 machine and change the workgroup name in the network neighborhood to the name of my windows 2000 domain cause this machine was a member of NT 4 domain before.

Please note that my NT domain and Windows 2000 domain are two seperate domain and there is no connection between these two.

I restart the windows 98 and try to log in using the windows 2000 domain account. yes i can but immediately after this login screen it shows another login screen which requires me to give user name and password again. And to get over this second login screen i have to use the user account for the NT domain otherwise can't.

So What is the problem ? Why I have to login 2 times ?

Thanks,

There is an old password saved in Windows 98. Windows 98 has a habbit of doing this (be design). To remove it Go to Start==>Run==>type sysedit and click ok.

In the system.ini file in that Windows you will see a section called [Password Lists] with entries that end in *.pwl. Remove all these lines, save the file and restart and see what happens.
