Re: domain controller error
First reboot once your PC and if that does not work then:
when you login with your local admin account are you able to ping the DC? Also, check the IP settings to make sure they are correct. Are you using DHCP or are you static? If you are able to ping the DC adn IP settings are correct, is the computer name in Active directory? Also if the computer name is in active directory, is it disabled? If you check all these things and you are still having issues, drop the computer from the domain, rename it and create the new name in Active Directory and then add the computer back to the Domain. Somewhere along the line of following these steps, you should get the computer back inline. If other computers are able to connect to the domain then it is definitly an issue with this computer name or a setting on this computer.

first you need to setup the roles in the server, go to the manage server console, ( can be found as a shortcut in the taskbar or under start menu ) then open the console and go to add roles.
1 - add active directory
2 - in the process it will ask you to install the DNS server role ( do it )
3 - after installing the role in the CMD command prompt type DCPROMO
4 - the DC controller installation and setup will beging ( do not do anything during this proccess )
5 - when asked by DC setup to choose what type of domain functionality level do the following
1 - windows 2003 ( this is for compatibility for windows server running 2003 and XP machines )
2 - Windows Server 2008 ( at this point nothing lower than XP can be added to the DC of course domain functionalities will increase - Only other 2008 server domain controller can be added and cluster migration from server 2003 to 2008 is not supported. )
3 - Windows Server 2008 R2 ( at this point only machines running Vista and 7 can be added to domain - windows xp is no longer supported. All the functionalities of the domain controller are available)
keep in mind once you promote the domain controller to a higher level it can't be brouht to a lower level.
once active directory is installed restart you server and the you should be able to add the clients pc or laptos to the DC example
- right click over my computer icon - click on properties - computer name - change the computer from workgroup to domain - type your FQDN ( fully qualified domain name) example: mynetwork.local or mysite.com - apply changes and restart - your computer will be part of the domain next time system boots up.
Ah this is an easy one, make sure the laptops MAC address (this can be found by going into the laptops command line and typing 'ipconfig /all') Then you need to go into Doman users and computers (active directory) and add that MAC address to the computers group. If this doesn't work...make sure your laptop is connecting through the same network. use the cmd line tool Ipconfig /all to find out the ip address of your server and your laptop. If your laptop's default gateway doesn't match that of your server's...you could be cross networking. Try the "ping" command like this go to the command line on your laptop and type Ping <ip address for server> if you can ping it, you can connect with it....also check your group policy that enables wireless connections.
This is usually a computer trust issue, if the computer was previously used to logon to the network and has been rebuilt or had in problems it can have trust issues. First way would be to change the computer name and add the DNS Prefix for your domain. ex desktop.abc.com to desktop1.abc.com. when prompted it is best to use the domain admin or equivalent to make the change and then reboot.
The resolution and workaround to solve the error is as below.
Login to the Windows 2003 domain controller, and delete the computer account object from the Active Directory by using Microsoft Management Console (MMC) which you can always access from “Manage Your Server”.
Log-in to the PC workstation as local administrator. If you cannot logon as local administrator, try to unplug the network cable and logon to the computer by using a domain administrator user that used to logon on the PC before, by using cached logon credentials feature.
Go to Control Panel, then click on System icon, then go to Computer Name tab.
Unjoin the computer from the domain by clicking on “Change”. You should see that Domain button is now selected. Remember your domain name in the text box. Select (Click) on “Workgroup” to remove the computer from the domain, and put any workgroup name in the text box (e.g. workgroup).
Click OK to exit.
Restart the computer (optional)
Go back to the Control Panel, launch System properties and then go to Computer Name tab, and click on “Change”.
Rejoin the domain by uncheck the Workgroup button and select (check) Domain button, and put in the domain name noted above into the text box.
Click OK to exit.
Reboot the PC.
This should solve the unable to logon to domain error, without changing or losing the user profiles on AD.
