Starfleetsnoopy -> ForestPrep and DomainPrep (14.May2007 10:25:25 AM)


Need an answer to a question.  I have 1 Server that is
running OS 2000 with Exchange 2000 running in my domain right now.
I have another Server that is running OS 2000 and I would like to
install Exchange 2000 on it. I have read that you must run ForestPrep
and DomainPrep before you install Exchange 2000 on a new server is this
true?  Or can I skip the ForestPrep and DomainPrep when there is an Exchange server all ready run in a domain.
My goal is to remove Server 1 from my domain.

Thanks for your help [8|]

Hiya, if you already have an Exchange 2000 installation and you intend to add an addtional Exchange 2000 box into the same domain then you will not need to run either forest or domain prep again.

Hope that helps,

Cheers

A

Since you mentioned that, eventually, you want to remove the first Exchange server.. make sure you read the article below before you do that.

I'm going to jump into this post since it involves adprep. I am having a lot of throuble with this. I have a Window's 2000 network that I am trying to set up a new server with Server 2003. Everytime I try to run adprep on the current DC I keep getting:

"There is a schema conflict with Exchange 2000. The schema is not upgraded."

Oh, by the way, I have Exchange 5.5.

Here is what I have done.:
Used LDP.exe to look for duplicate or mangled LDAP entries. 0 found.
Ran LDIFDE.EXE to import inetorgpersonfix.ldf. It was mostly successful. I only had 2 entries that were changed.

I used LDP.exe to search for the correct LDAP entries. Out of the 3, I am missing labeluri. What information I have found says that if one of the entries is missing it doesn't matter. Also, houseindentifier looks different on my system that in other documentation. Does this look normal?

"CN=ms-Exch-House-Identifier"

After all of this I still can't run adprep. Everything that I am finding says to do the above 2 things. Right now I am just spinning my wheels. Any help would be greatly appreciated.

Thanks
David

Okay, go slow for me. ;)

You currently have: A Windows Active Directory 2000 domain. Is it in mixed mode or native mode?

An Exchange 5.5 server. Is it on a domain controller or on a member server?

And you want to do.. what? Upgrade to.. Exchange 2000 / 2003 /  2007? Or Active Directory 2003? Or Ex '00 / '03 / '07 and AD '03? Or just add an Exchange 200x server and keep the old Exchange 5.5?

Basically, what do you have now and, when all is said and done, what do you want to have?



vrtc350 -> RE: ForestPrep and DomainPrep (3.Jul.2007 7:48:26 AM)

I have a W2k network running active directory. I am actually trying to move the AD to 2003. When I run adprep.exe I get the mentioned error. The network is in native mode.

I am running exchange 5.5 on a member server.

I have one DC in this network running Server 2k. I have purchase a new server to replace this DC. It runs Server 2003. I can not promote it until I run adprep.

Is 5.5 the issue? I have ran all of the fixes I can find for this error. I forgot to mention that I have also ran "load_iop.bat" as well. Nothing works.

We are planning to upgrade from Exchange 5.5 later this year. However, like I said I'm not trying to do this right now. Would doing the upgrade now get rid of this headache?

Thanks
David



jassyca -> RE: ForestPrep and DomainPrep (3.Jul.2007 4:59:10 PM)

Have you seen this?

"Windows Server 2003 adprep /forestprep command causes mangled attributes in Windows 2000 forests that contain Exchange 2000 servers"
http://support.microsoft.com/kb/314649/en-us

I'm not real excited about the above article because you don't currently have an Exchange 2000 server so it doesn't quite fit your problem.

There's also this:

"Schema mismatch" error message occurs when you try to run the Active Directory Installation Wizard (dcpromo.exe) in Windows 2003 or Windows 2000
http://support.microsoft.com/kb/838179/en-us?spid=3198&sid=1493

That sounds a little closer to what you're seeing but I'm not really excited by it either because, the way the article reads, it sounds like this error comes up because there's something goofed up in AD somewhere. A corrupted AD?! Yikes!

Lastly, I found this:
http://www.microsoft.com/communities/newsgroups/list/en-us/default.aspx?dg=microsoft.public.win2000.active_directory&tid=2bec5339-5553-4190-8a32-e8fe16ff0a8e&p=1

That last link seems to, again, indicate that there might be something not quite right about your AD. In the above case, someone apparently started the process of installing Exchange 2000 but then quit. I wonder if there's a way to know where in the process they stopped? Anyway, this person got the exact same error message that you said you got. Of all three, it sounds the closest to what you're running into.

If none of those help and you're still having trouble, can you answer a few more questions that I stupidly forgot to ask: What OS is the Exchange server sitting on currently? Win2k, Win NT 4, Win 2003? And do you know which domain controller is the Global Catalog? Or domain controllerS, if you have more than one doing that. (Although, from your message, it sounded like you only have one DC, yes?) You using the "adprep" on the Win2003 cd not the Exchange cd, yes? When you try adprep, is the account that you're using a member of the "Schema Administators" and "Enterprise Administators" groups? Also, can you try adprep one more time and write down the specific error message? And explain to me the steps you took. "I logged on to the domain controller using my domain account which is a member of the domain users, domain admin's, schema admin's and enterprise admin's groups. I put the Win2003 cd in to the server's drive, browsed to the program on the cd. Then I took a huge swig of coffee (two sugars, no cream).." Okay, you don't have to get quite that detailed but you know what I mean. [;)]

What version of Exchange are you planning to upgrade to? Exchange 2000, Ex2003 or right to Exchange 2007?
