I currently have a file server on my network that is also a domain controller. It is running Server 2003 but Active Directory is in 2000 Native Mode. I also have Security Groups in Active Directory that specify what users are allowed to access on that server. It is the only Windows domain controller.
Old Domain Controller: server.olddomainname.com & File Server
New Domain Controllers: server1.newdomainname.com & server2.newdomainname.com
I have built a new Active Directory domain with a primary and secondary DCs and adding an Exchange 2007 server. Both DCs are Windows Server 2003 in 2003 Native Mode. I need to know how I can retain permission for those security groups on the old domain after demoting the file server/old domain server and then joining it to the new domain. I have already created the same Security Groups in the new domain in hopes that I will be able to use them. Another kink in this rope is our old account naming structure was <firstname>_<lastname>. I am changing this to <firstinitial><lastname>. My intention is to ease the amount of typing to log in and allow easier email capability.
Please let me know if you need any further information. I am grateful for any assistance...
