Let me see if I can make this a little clearer. What I am asking has to do
with the Exchange 5.5 LDAP service and the Windows 2000 AD (LDAP service)
when both AD and exchange 5.5 are installed on the same box.
1. When installing Exchange 5.5 onto a Windows 2000 DC you MUST change the
LDAP port from 389 to 390 because the AD uses the default LDAP port of 389.
2. When performing an in-place upgrade MS says that the upgrade process will
fail because the Exchange 2000 setup process will look for the Exchange 5.5
LDAP service on port 389.
3. Microsoft recommends that in this scenario you change the Exchange 5.5
LDAP port back to 389 and re-run the setup.
My question was: At the point you change the Exchange 5.5 LDAP port back to
389, the active directory is still using that port. How can the Exchange
5.5 LDAP service be accessed on port 389 when that port is already in use by
the AD?
Has anyone done an in place upgrade of an exchange 5.5 server running on a
Windows 2000 Domain Controller?

I could not fully grasp your question. However, when you migrate an Exchange
5.5 server to Exchange 2000 In-place, the Exchange 5.5 site becomes a mixed
mode site. In mixed mode you have SRS (site replication sevice) which
replicates information from Exchange DS to AD. This SRS listens on LDAP port
379. Once you migrate to Exchange 2000, your two way connection agreemnets
automaticaly change/reconfigure to port 379.

I am going to be performing an in-place upgrade of our Exchange 5.5 server.
The process is pretty clear with the exception of the reconfiguring of the
LDAP port.
The course, as well as the MS KB article (Q255256: XADM: Upgrade Fails When
Exchange Server 5.5 LDAP Port Has Been Reconfigured):
"Generally, the LDAP port is changed so that a domain controller, Microsoft
Exchange Server 5.5, and Active Directory Connector (ADC) can all be run on
the same computer. When an upgrade is performed, however, it expects that
the Exchange Server 5.5 directory is listening on the default port (389)."
This is exactly the situation with our Exchange 5.5 server. The LDAP port
on the Exchange server is currently 390. The ADC is already installed in
our case and is configured to use port 390 for exchange LDAP. I take it
from this article that the setup program itself also access the Exchange 5.5
server (in addition to the ADC access it) via LDAP to obtain site
information.
To work around this problem the article states:
1. Set the ADC to Replicate Never.
2. Change the LDAP port on the Exchange Server 5.5 computer back to
389.
3. Re-run Setup.
4. After this, the ADC won't be needed for this particular server, and
you can remove it or point it to another Exchange Server 5.5 computer.
Even if the ADC is not replicating, port 389 will still be taken by the AD
LDAP service, will it not? If so, then it will still not be able to connect
with the exchange 5.5 ldap service as it will not work due to the fact that
the port is already taken. The article does state that this solution is for
the scenario when Exchange 5.5 is installed on a Windows 2000 DC however, so
I am a bit confused as to how this will work...
Can you help me understand the process here? Do I have to allow the setup
to fail first with the port as is, then reconfigure it to 389?
