I have a windows 2008 ENT x64 server I am trying to add to an existing windows 2003 domain.

Thus far I have done forest and domain prep, I have created answer file when I run it I get a FQDN error. I can ping both domain controllers and I checked firewall settings still no luck

Below is the error I get
You must specify the fully qualified domain name (FQDN) of the domain in which you want to add this additional domain controller.

When trying to use the domain...
I assume internally you are something like company.local
??

If so when trying to join the domain thats what you need to put in

my configuration file is as below

[DCINSTALL]
UserName=acc\administrator
UserDomain=ACC.INT
Password=password1234
SiteName=Default-First-Site-Name
ReplicaOrNewDomain=replica
DatabasePath="%systemroot%NTDS"
LogPath="%systemroot%NTDS"
SYSVOLPath="%systemroot%SYSVOL"
InstallDNS=no
ConfirmGC=yes
SafeModeAdminPassword=password1234
RebootOnCompletion=yes

Commented:
UserDomain=ACC.INT


thats not a properly formed Doman name....
Go to an existing server and then into system properties is that the same domain name?

the internal FQDN is ACC.INT

the servers fully qualified name is DACC2.ACC.INT

when joining machines to the domain that is the DNS domain name and the netbios name is just ACC

Commented:
have you tried just ACC?

Yes, make sure you use the DNS name like "company.local" (not the NetBIOS name)
Also, to resolve dns, you need the target domain's DNS server(most likely the DC) as your primary DNS entry.

did you delete the NewDomain* and made sure that the Forest and Domain levels were correct?

This is what I get now


C:\Users\administrator.ACC>dcpromo /answer:C:\setupdomain.txt
Checking if Active Directory Domain Services binaries are installed...
The specified argument 'DomainDNSName' was not recognized.

This is the below script I am using

[DCINSTALL]
installDNS=no
DomainDNSName=acc.int      
DomainNetBiosName=acc
SiteName=Default-First-Site-Name
ReplicaOrNewDomain=replica
ForestLevel=2
DomainLevel=2

LogPath="%systemroot%\NTDS"
RebootOnCompletion=yes
SYSVOLPath="%systemroot%\SYSVOL"
SafeModeAdminPassword=!qazxsw2

I used a Full Verision of Windows 2008 to create the answer file from the GUI. I then had to add the DNS server as a delegate to my current AD

All is okay now

; Replica DC promotion
ReplicaOrNewDomain=Replica
ReplicaDomainDNSName=acc.int
SiteName=Default-First-Site-Name
InstallDNS=Yes
ConfirmGc=Yes
CreateDNSDelegation=No
UserDomain=acc.int
UserName=*
Password=*
DatabasePath="C:\Windows\NTDS"
LogPath="C:\Windows\NTDS"
SYSVOLPath="C:\Windows\SYSVOL"
; Set SafeModeAdminPassword to the correct value prior to using the unattend file
SafeModeAdminPassword=
; Run-time flags (optional)
; CriticalReplicationOnly=Yes
; RebootOnCompletion=Yes

The comment of looking into the script was important, although it did not directly resolve the problem is pointed my in the correct direction
This problem happens when a DC is already in place. Means if the DC is already installed on a server, and if you try to execute the same dcpromo from command and the promotion switches, it won't work.
