HELP!!
It’s now Monday – 00.05am and several hours ago we finished repartitioning our old DC and had installed Windows Server 2003.
We have created two user accounts – each account is a member of the Administrator Group, Domain Admins and Domain Users, and we are unable to add a computer to the domain using these accounts. We have also created the relevant computer accounts on the DC. When we try to add the computers (right-click my computer>computer name>then use either Network ID or Change), the system recognises that there is a computer account, but then gives an access denied message after we supply the username and password of a domain admin account.
We have also used group policy (ADUC – right-click Domain controller, GP Pol tab>Edit>Computer configuration>Windows settings>security settings>local policy>user rights assigment) and added both the user accounts to Add computers to the domain policy setting.
I had exported all the AD directory objects from the old Win2k AD by using the LDIFDE command, but when I try to import this information there is an error saying the domain name already exists. When we created the new domain using the DCPROMO command we gave it the same name as the previous installation.
The firewall is disabled by default according to the services snap in.
The DNS server has been started on the DC. The network card is setup with a 192.168.0.1 address, 255.255.255.0 subnet mask and the IP address of the router for Internet connection. The other computers that already exist on the network (but which are now sitting outside the domain), all have static IP addresses.
We have also tried removing the computers from the old domain, joining them to a workgroup called WORKGROUP and rejoining the new domain without luck.
