Active Directory Server 2000

burbankmarc

Hey all,

I frequent the Cisco and Linux forums here but I have an MS question. I am not an MS guy so you might have to talk slowly to me.

Anyways, I want to upgrade my domain controllers from 2000/2003 to 2008 R2. I first want to test this upgrade process. I installed server 2000 on a PC added it to the domain and made a domain controller. I then had a complete copy of the AD forrest so that was cool. I then moved it to a private network and stuff stopped working.

I wasn't able to do anything for AD because it couldn't contact the other domain controllers, so I seized control of all the roles I could hoping that would be it. Well it wasn't and now it seems to work even less.

So my question is how do you pull a working Domain Controller and move it to a private LAN for testing?

Devilsbane

I wish I could answer your question, but I have never done this.

What I do know is seizing control of the FSMO roles is almost always a bad idea. Something breaks pretty much every time. But I think you already learned that one.

I am not sure why you are doing it the way you are unless you want a test domain? anyway you can build a DC allow it to replicate then move it and seize the roles. BUT you have to do some housekeeping afterwards.

Your new and seperate domain needs to be treated as if all the other DC's have failed so you need to do a meta data clean as per
Delete Failed DCs from Active Directory

You should also remove them from sites and services as this is not done for you.

Clean up DNS, and run dcdiag /test:dns ignoring any post reboot events anything other than that you would need to be more specific about what is not working.

Also ignore anything in the event logs right after a DC reboots, in fact what I do is just clear all events and just watch for new ones.


Just make sure you do not move that DC back to the other network.

burbankmarc

Yeah, I did learn that the hard way, which is why I love testing things.

Ok, so maybe I can't just pull it from a live environment and throw it onto a test environment, but is there a way I can export the AD on the live servers and import it onto my test machine?

*EDIT*

Thanks Mojo, let me go test that out and see what I come up with.

Well if you allowed it to replicate it should have a copy already, that's how it works, or am I not understanding what you have done?

Mojo_666

BTW I would also advise a transitional migration not an upgrade, unless you have a reason for doing so.

burbankmarc

Ha, well I tried the metadata cleanup, but the servers weren't listed so I didn't have anything to clean. Now, however I cannot even connect to AD.

I guess I'll have to wipe the system and start again, no biggie.

Well that's what I was banking on, the replication, which worked perfectly. However, I didn't know that if you pulled it off the network it would break everything.

I guess I was curious if I could just export AD from one network then import it to my test machine.

Well I don't know what that means, but sure. I just want to get off these old OS's. So whichever way works best is fine by me.

ajs1976

What DNS server is your test box pointing to? Itself or one of the other DCs?

Well you can get it going, all these things are fixable it's just how much time and effort do you want to spend doing so? I have a few hours to help but you might be better of starting from scratch as its a lab setup...your call.

Transitional means just that you transition over to 2008, so you would basically build a 2008 DC on to your domain MOVE roles to it, get it all working then decom an old server, rebuild it to 2008 make it a DC and so on until all your DC's are 2008 rather than what is effectivly an OS upgrade.....make sense?

Just to add to this, pretty much every issue you will have is going to be related to DNS, but this is the first thing to check.

If it is not pointing to itself then configure it do do so, then at the command prompt type

"ipconfig/flush dns"
then
"net stop netlogon && net start netlogon"

The run dcdiag /test:dns to find any other dns issue's

I wouldn't mind fixing these things. I could probably use a deeper understanding of how Microsoft servers work.

And that was exactly my plan. I was going to put a new 2008 server on the domain, replicate all the data to it, then slowly decomission the 2000/2003 servers.

Ok, so how would I fix the problem where I can't connect to AD on my test machine?

Thanks a lot for the help, btw. I appreciate it.

Mojo_666

As ajs1976 said, start with the local DNS configuration, post an ipconfig/all output from the DC

burbankmarc

Word up, it was the DNS. I can connect to AD and make changes. I removed all the "failed" DCs. So now my test machine is the only one.

Now, as a test I tried adding my test 2008 server to the domain, but it failed out. It says it can't find the domain. It's DNS server is pointed to the server 2000 test machine.

Happy days, first thing make sure the 2000 box is working ok, no events etc, dcdiag looking ok and so on, make sure you have no firewall running then try again, but again check the ip config of the 2008 box, it needs to be on the same subnet or have a route and it needs to be looking at the dns servers of the domain you are wanting to join etc.

But make sure the 2000 box is ok as above, maybe even give it a reboot for good luck.

Don't worry, I got the networking portion.

There is no firewall.

Ok, I also rebooted both of them for good measure.

This might be a bit off as it's 2000 but Go into sites and services drill down to you Server, expand till you see NTDS, right click > properties and put a check in Global Catalouge.

Then verify SRV records as per the below articles

http://support.microsoft.com/kb/241515
http://support.microsoft.com/kb/241505

burbankmarc

Ok, that was easy enough. What did that do?

Mojo_666

You need a Global Catalouge server for your domain, by default this is created on the first DC but as you skipped that part you needed to do it manually.

Check the edit I made also for the GUID error and follow those links, but this might not cause you an issue short term but good to fix.

burbankmarc

Ok well I noticed that I didn't even have DNS services installed. So I installed them and ran dcdiag again, now almost all the tests are passing. I'm still getting an FSMO 1355 error though....lemme grab the output and post it.

One to add to your check list for next time..

While you are checking stuff can you check the DNS has the following zones, I suspect you might be missing the _msdcs zone

_msdcs
_sites
_tcp
_udp

burbankmarc

msdcs is in there, it has my 2000 test machine listed as offering the service.

Mojo_666

Ok you should be good to go but it might be worth running "net stop netlogon && net start netlogon" from the command line just to re register the SRV records.

Once done try adding the 2008 server to the domain again.

burbankmarc

Cool thanks for all the help. This has been pretty informative.

Still cannot connect though. I tried the full domain too of mapcom.local. If I ping mapcom.local from my 2008 server it returns the address of the 2000 DC.

What message is being returned? cannot find domain? any remaining errors on dcdiag /test:dns output from the dc?

burbankmarc

It says "AD DC for domain mapcom.local could not be contacted" -paraphrased.

dcdiag /test:dns - tells me that isn't a valid test.

The FSMO test is still failing, though.

Maybe it is not valid on server 2000, could you post the output of the FSMO error?

I went through a fix on microsoft's website. Told me to change the value of burflag in the registry, that didn't seem to work though.

However, the 2008 server is now prompted with an authentication box when trying to join the domain. Baby steps, but still good news.

Authentication is not working. Well, that might be misleading, authentication appears to work but it tells me there might all ready be a computer with that name on the domain. I changed the name and it the error still came up.

It tells me to "remove any stale conflicting account"

The do just that, places you need to check Are AD Users and Computers, sites and services or rename the server to something you know 100% has never been used on the domain.

Mojo_666

Could you also check the output of "netdom query FSMO" and see if netdom agrees that you dc holds all roles.

Mojo_666

Also check DNS for the existence of _gc records (SRV) records, these should reference your server. If they do not exist restart the netlogon service, this should register those records and therfore advertise the service, if they do not get created they can be created manually.
