You need to use ntdsutil to remove the metadata.

You were probably selecting the wrong server, make sure you pick server2 when you get to this step:

13. Type select server number, where number is the number associated with the server you want to remove. You receive a confirmation listing the selected server, its Domain Name System (DNS) host name, and the location of the server's computer account you want to remove.

Yeah, I know he's told me to that already . But the problem is I cannot complete the remove operation. It just says "Selected server cannot delete its own metadata.

Andrew, I am not selecting the wrong server. I am selecting server2 man. I am having a look at experts-exchange to see if they have someone who had this problem of not being able to remove metadata.

Can you confirm you are you picking server1 for this step?

under "Procedure 1"
5. Type connect to server servername, and then press ENTER. You should receive confirmation that the connection is successfully established. If an error occurs, verify that the domain controller being used in the connection is available and the credentials you supplied have administrative permissions on the server.

Do you mean that I connect to server1 in this step even though I am physically at server1?

astorrs

Yes, you only use server2 when you are selecting the one to delete in step #13

I will give that a shot as soon as I get home from work. Seems it will work now as I was not doing it at the right server.

Essendon

There's been some respite from the problems it seems, finally

As Andrew pointed out that I wasnt connected to the right computer which was why I was getting the error that the selected computer cannot delete own metadata.

This time I connected to server1 and then did the cleanup on server2 and got the following message when I hit enter at the final step:

Removing FRS metadata from the selected server.
Searching for FRS members under "CN=server02,dc=contoso...."
Deleting subtree under "cn=server02,dc=contoso.com....."
The attempt to remove the FRS settings on "cn=server02,cn=default-first-site,cn=sites,cn=configuration,dc=contoso...." failed because "Element not found"

metadata cleanup is continuing
"cn=server02,cn=servers,cn=default-first-site,cn=sites....." removed from server server01

Is the above normal in this scenario??

I also followed all instructions in the following link, (after the above steps) http://www.petri.co.il/delete_failed_dcs_from_ad.htm

I have deleted all records of server2 from the DNS snap-in on server01, i.e. SRV, A, CNAME, and MX. And also deleted server2 in AD Sites and Services.

server2 disappeared from the DC's OU automatically.

Seems things have gone quite well, which is a relief. Now please give me some advice.

1. I should never turn server02 on again? It was a virtual machine anyways, so I delete the machine in VMWare?
2. I should not name a computer server2 again as it might revive the computer object?
3. How do I tell for sure that there an no traces left of server2? (nslookup etc.??)

Thank you for your help everyone, especially Sie and Andrew.

Yes the missing objects were a part of the problem as to why the DC wasn't functioning (the dcpromo only half worked).

1. Yes, delete the VM (aka "reformat" the hardware)

2. You can reuse the name. All records of it should be gone.

3. Do an NSLOOKUP for server2 and enable Advanced view in ADUC and perform a search just to be safe, but you should be fine.

P.S. You're 290/291 adventures while they are more difficult than most are still giving you some great experience.

dont forget the DNS setup procedure either, do you want dns on server 2 cause if you do dont tell server 2 to use server 1's dns while you install DNS. it would more than likely return an error saying it cannot set up dns because of some issue.

am i making myself clear? lol.

Undoubtedly have! Thank you for tips.

server2 had been pointing to server1 for DNS. But the problems were because server2 had not been correctly promoted to DC.

Now that server2 is dead and server1 has no knowledge of it, I am getting some very welcome event logs, with some saying "All problems preventing file replication have been resolved..." and "Server1 is now replicating with other DC's".

Thank you all once again!

P.S. Next time I promote a server to DC I am going to do scrutinise the process very carefully and scour the event logs for any illnesses!

Here's another tip (if I haven't told you before) look for those shares (net view \\<dc name>) as its basically the last thing done after AD loads.

And just to be safe, maybe do a dcdiag and make sure everything is kosher.

You already have told me that, but thanks for ramming home the point.

Will do.

P.S. I have a few more questions, that I'll post shortly in a new thread.

Sie

Glad to see you got it sorted!
