The specified domain either does not exist or could not be contacted" error message in Windows Server 2008

DC2 was running with the AD DS role prior to DC1 crashing?

Did you run a metadata cleanup for the crashed box 192.168.0.20


http://technet.microsoft.com/en-us/library/cc816907(v=ws.10).aspx

You also mentioned it was the "main" DC.  Does that mean it held the FSMO roles?

Were you able to transfer or seize (since it crashed) the roles.

Thanks

Mike

yes DC2 was running ADDS role before DC! crashed

yes DC1 was running FSMo role. what is the command to clean my dc1 using ntdsutil metadata cleanup server ip address was 192.168.0.20

In my active directory users and computer, domain controller i don't see my DC1 i only see my DC! at present

Please provide the following output from DC2:

netdom query fsmo

use the link for the metadata cleanup (easier in 2008 which is nice)  seizing the roles is still done through command line   http://www.petri.co.il/seizing_fsmo_roles.htm

Thanks

Mike

C:\Users\administrator.NORTECPK>netdom query fsmo
Schema master               NORTECSERVER.NORTECPK.local.com
Domain naming master        Nortecserver4.NORTECPK.local.com

RID pool manager            Nortecserver4.NORTECPK.local.com
Infrastructure master       Nortecserver4.NORTECPK.local.com
The command completed successfully.

the first schema master server nortecserver.nortecpk.local.com is the one with ip address 192.168.0.20 which is crashed.

in my active directory site and services i see my old server with NTDS settings do you want me to delete that?

yes delete the old server and go through metadata again just to be sure.  It looks like someone has done some of it because most of your FSMO roles have been seized to Nortecserver4.

You can seize the schema master.

Thanks

Mike

norteserver4 is my DC2 which is currently running.

Please let me know what to next

No stop. Do not delete.

Your environment should still be able to service clients even with the schema master on the failed server.

Do you have failed DNS settings on each of your clients (DC1 and DC2 IP addresses)?

Here's how you seize the role from DC1.

ntdsutil
roles
connection
connect to server Nortecserver4
quit
seize schema master

As for metadata cleanup mentioned above, here's the official link from Microsoft:

http://go.microsoft.com/fwlink/?LinkId=80481

please let me know how to seize schema master role on my DC2

When said delete I meant delete the failed/crashed DC if it is still in AD > that is the metadata cleanup in 2008

steps to seize the schema master are here   http://www.petri.co.il/seizing_fsmo_roles.htm

Thanks

after running seize comminad  i am getting follwoing error.

do you want me to delete that server from activedirectory site and service and then run ntdsutil for seize schema master role?

Just to verify, run another results. Run netdom query fsmo again.

You seized successfully. Make sure that DC never comes back online. You can delete from Site and Services if you choose.

please see attached file. the first one is nortecserver which is 192.168.0.20 you want me to delete that right?
Doc2.docx

you are right see the result below.

C:\Users\administrator.NORTECPK>netdom query fsmo
Schema master               Nortecserver4.NORTECPK.local.com
Domain naming master        Nortecserver4.NORTECPK.local.com

RID pool manager            Nortecserver4.NORTECPK.local.com
Infrastructure master       Nortecserver4.NORTECPK.local.com
The command completed successfully.

so now i am going in to activedirectory site and service and remove nortecserver (192.168.0.20) including NTDS settings right?

Right click on NTDS Settings (which is highlighted) and delete. I should remove cleanly.

I deleted. now what is the next step? do i need to restart my server?

You can just restart Active Directory.

net stop ntds & net start ntds

I would start working on establishing another DC as quickly as possible.

i will test and let you know.  so you recommend that i should add another domain controller in the AD?

Yes. Transfer the schema and domain naming master to your new server so you have a happy balance. Make sure you configure the next DC as a GC.

Good luck with everything!

my programmers are still testing the server i was connetd remotely to the server.

One last request. i do have another server in the network how do i add that and backupdomain controller or additional domain controller if you want i can open another question for that.

You can run dcpromo on the member server.

after DC promo how ai am going to Transfer the schema and domain naming master to your new server?

From you new DC run the following commands:

ntdsutil
roles
connection
connect to server <your new DC>
quit
transfer schema master
transfer naming master

in dns server i am getting this error see the attachment
Doc3.docx

Do you have a DNS entry for yourself?

127.0.0.1 or your IP address

now my remote engineer is telling me that we do have naother server which a=was installed primarly 192.168.0.10. so when i do netdom query fsmo i get follwoing result

so when any work station is trying to register in domain it is not taking 192.168.0.40 as primary domain controller ip address. what could be the problem see attachment for 192.168.0.10 active directory users and computers , domain controller it show both domain.
Doc4.docx

please let me know what is causing this problem

If you want i can open new question for this problem.

Please advice so i can accept the solution for this question and close thei open question.

thanks for your expert help yesterday

Very quick response to my all the questions

it might also be your SYSVOL and NETLOGON shares are not available.
Please try to type in the addressbar of Windows Explorer: \\servername\SYSVOL\


My problem resolved by changing a  small registry entry change and a reboot of server.
