Stuck in loop in dcpromo.exe

Hi everyone,

I'm trying to do a clean install of a Windows 2008 Server Standard but I'm having a problem that I have not found on the net yet, so I'll try to explain here.

I cannot drop any screenshots since I'm installing the new server on 3 HD's Raid5 in the same case as the one running a Win2003 server now. So I won't be able to try some manoeuvers too.

Problem:

The installation worked (RAID5), installed NIC driver and being able to connect to internet without problems.

I installed the AD function and was trying to install the DNS server with dcpromo.exe.

With our without 'the Advanced settings option', I can:

- create new domain in new forest

- type the FQDN (.be, .com, .***** .crap, even a single title)

- choose the forest functional level (win 2008)

- he verifies name use and netbios, all are fine

...

After this he starts examining the DNS settings... for ages...

I tried options like different FQDN, different FFL... nothing helps.

I also tried uninstalling the AD function and reinstalling it. Then I tried to install DNS function first but then he says I have to do everything else manual (I tried but lost a lot of time checking errors).

The only thing I haven't tried is the unattend file because lack of time.

Who has an idea?

Here are some specs:

IP address: 192.168.0.250

subnet: 255.255.255.0

gateway: 192.168.0.1

dns: 192.168.0.250

alternate dns: 193.74.208.135

Thanks
