Amateur Mistake

Posted on 2009-07-11

So I promoted a windows 2003 server to a DC after demoting another in the same site, the old server contained DNS, DHCP, etc.  I forgot to point the new server's DNS to the primary controller, and then promoted it.  Now when I try to log in I get the following error:

The system could not log you on due to the following error:
The specified domain either does not exist or could not be contacted.


On the primary server, the DNS records still point to the old server.  Is there a way to demote the new server via the command line?  I can access the system using PSExec and running cmd.exe on it.

Thans in advance for you help!

Steve

The only way to demote is dcpromo. Were you able to join it to the same domain, or did you end up creating a new domain? Is it safe to assume that your DNS was AD integrated? Do you have any other DCs in this domain? What is holding the FSMO roles? What DNS records are still pointing to the other server? Are both servers named differently?

You should also be able to access the system via DSRM mode

You specified that password during promotion.  You can change the DNS settings that way.
Thanks

Tntmax: There is 1 other DC in another site, and it is contactable.  DNS is AD integrated. The other DC is holding all FSMO roles.  After looking a little deeper in DNS, it is not actually pointing to either the demoted server or the newly promoted server in anything.  and the demoted and newly promoted servers are named differently.

mkline71:  I'll check that out, and report back.


Thanks for the quick response.

I guess I should mention that I do not have physical access to this server, it's in another state.

What if you change DNS to point to the other DC? Did you enable zone tranfsers in DNS? What errors are you getting in the event logs?

So at another state I'm guessing you can't dispatch a tech at that location.
With psexec and netsh you should be able to add a DNS address
http://www.petri.co.il/configure_tcp_ip_from_cmd.htm
That shows you how to configure a static IP for DNS using netsh use that in combination with psexec.
Thanks

I think the most simple way is just "kill" this server and after that cleanup your AD.

Sorry, but you can take a lot of work hours to try to fix this error or past just 3 hours rebuliding this server.

I'm  guessing you don't have DRAC or iLO on the box

sorry for the delay getting back to you, I was having internet issues at the house.  I do have a drac on the server, so I could theoretically use that to get into ds restore mode.

mkline71 I have already used psexec and netsh to assign the proper dns server, however it still won't let me log in.  When I promoted the server it was pointed at the old server so the primary DC didn't get the DNS updates that come with a dcpromo and therefore does not recognize the new dc as a real dc?

I was having difficulties with the drac card, but now for some reason it's working.  I was able to log in using that console.  Strange how mstsc /admin doesn't really connect to the console...I'll keep everyone updated.

after finally getting into the server, I had to do a dcpromo /forceremoval because the primary DC was not aware that the server is a DC...I'll do a re-promote later.

Thanks everyone for the input, I'll split the points among all of you.
