Exchange 2003 can't run Forestprep

I am trying to install the first exchange server in the forest/domain.  After installing it the first time I found that there were remnants of an old Exchange organization in active directory.  I uninstalled exchange 2003 and removed all remnants (including registry) of any version of Exchange as outlined in an MS article.  This process did remove the exchange attributes from the schema.

Now when I go through the steps to deploy the first server, I get an error when I try to run ForestPrep:

"The component "Microsoft Exchange Forest Preparation" cannot be assigned the action "ForestPrep" because:
-To install the first Exchange server in a domain or to run setup in "ForestPrp" mode, you must be an Exchange Full Administrator at the organization level.  You must use an account that has been granted the Full Exchange Administrtor role in the Exchange organization using the Exchange Administrative Delegation wizard."

I am using the Enterprise admin account which is also schema admin, local computer admin and domain admin.  I have even installed the Exchange System Management Tools and used the delegation wizard to make sure that the account has the Exchange Full Administrator role.  The schema is not extended and I do need to run ForestPrep etc.

I am at a loss...help!

Can you verify that you have performed all of the steps listed below?

You may want to review this as well.  You could very well have some remnants floating around.

You run forestprep on the schema master, please check if you are running the command on a Domain controller that hold this role.

Also if you still have the Groups Exchange Domain servers and Exchange Enterprise servers make sure that your Exchange Server is listed as being apart of those groups in AD users and Computers under the "Member of" Tab of the properties of the exchange server

You don't have to run it on the schema master, just from a machine that has access to the Schema Master.  It would not hurt, however, to perform the DCDiag steps listed in the wizard, so that you can verify that the Schema Master is, in fact, up and functional.

Are you installing Exchange 2003 on Windows 2000?

I am running through the steps provided by Bob and have fond that there were some registry entries that I needed to delete.  I am going to make sure that I have exchange removed (I had installed the management tols succesfully) and then try the reinstallation again.  

I have tried running forestprep on the schema master and I did the dcdiag to test for availability.

I am installing exchange 2003 on Windows Server 2003.

I ran through all of the steps to remove Exchange completely.  I am back to getting the same error message when I try to run ForestPrep.

Can you install the Exchange system manager tools?  If you can install those, right-click on the Organization Name and run the delegate control wizard.  See what account is an Exchange Full Admin.  Run the forestprep again using that account, or delegate control to the account which you are using to do the install.
OR, if you remeber the account you utilized to perform the install, use that same account again.

If you need to see the security tab for the org, here is a link to the Microsoft site, which demonstrates how to do this:

1. Start the ADSI Edit snap-in. To do this, click Start, click Run, type adsiedit.msc in the Open box, and then click OK.
2. Locate the CN=Configuration,CN=Services,CN=Microsoft Exchange,CN={335A1087-5131-4D45-BE3E-3C6C7F76F5EC} container.

Note The CN={335A1087-5131-4D45-BE3E-3C6C7F76F5EC} container may also appear as CN=First Organization.
3. Right-click the CN={335A1087-5131-4D45-BE3E-3C6C7F76F5EC} container, and then click Delete.
4. Right-click the CN=Microsoft Exchange container, and then click Properties.
5. On the Attribute Editor tab, click the heuristics attribute if it exists, click Edit, click Clear, and then click OK two times.
6. Run the Exchange 2003 setup /forestprep command again.

Thanks for all of your help.  The links to the knowledge base articles and the other website were very helpful.  I think it was an entry in Active Directory that was preventing forestprep from running even though the acct had the correct privileges.  You guys are awesome!
