  Hi Sharath
   You should disjoin them from domain. Make sure when you right-click My Computer>Properties>Computername, in domain tab, your domain is not shown. If yes, change it to a workgroup.

  Computer objects can be seen in Primary domain controller. They dont get deleted when you disjoin a computer from domain. Would you please tell what did you do from the beginning? The demoted computer was a server? a DC?
folowing registry key may help for modifying domains listed in login screen
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Mrhusy

I have 3 systems in which i created a Domain lik
1 machine Domain Primary + DNS and exchange
2 Domain controller2
3 Child Domain

I tried demoting the child domain (3) but gave an error and later used the dcpromo /forceremoval and then removed the machine from the network.Later follwed the steps from these sites
If dcpromo failes to remove a secondary domain

And removed .Now every thing looks fine but just the listing shows 2 domain names.Even when i add a new fresh machine to the network and add the machine to the domain it shows these 2 domain names.

 Hi Sharath
     Did you check "this is the last dc on domain" while demoting child domain DC? I assume you did not check it and child domain info still exists. Check the following. Make sure you do the following for child domain.

So, when you follow the article I submit, at step 10 when you type list domains, do you see your child domain in the list?
