Windows 2003 ADPrep Fix for Exchange 2000

What do I need to do to make sure Exchange 2000 runs fine on my Windows Server 2003 forest?

If you‘ve installed Exchange 2000 into the forest before running ADPrep, you have to correct some mistakes that were made in the Exchange 2000 schema extensions.
Specifically, both ADPrep and Exchange 2000 define labledURI, houseIdentifier and secretary attributes, but Exchange 2000 does not use the correct LDAP display names (lDAPDisplayName) as defined in RFC 2798.
If you run ADPrep after Exchange 2000 has been installed without fixing these attributes, you can end up with duplicate schema objects with different lDAPDisplayName attributes.
To solve the problem, you must run the inetorgpersonfix.ldf file that is located in \support\ tools\support.cab. This LDIF file fixes the lDAPDisplayName attributes of the three attributes.
First save the inetorgpersonfix.ldf file, then import it using the ldifde utility. Here is an example where we will be importing into the mycorp.com forest:

​ldifde.exe /i /f inetOrgPersonFix.ldf /c "DC=X" "DC=mycorp,DC=com"

Note that inetorgpersonfix.ldf uses DC=X as the forest path, which is why we needed to use the /c switch to replace it with our own forest path.
