sabasigh -> Left over migration issue?? (8.May2005 7:29:00 AM)

Back in 2003 I began the process of migrating from Exchange 5.5 to 2000 on our Windows 2000 domain.

Installed the ADC, moved mailboxes...everything worked out fine, retired the old server, properly removed from site, etc etc etc.

Anyway, I'm now in the process of migrating services off of my main domain controller to retire it. I've brought up another DC, transferred roles to it, started DHCP, got DNS going, pointed Exchange to it. Everything is going just fine.

However, when I bring up AD Sites & Services, there is an Exchange folder next to the NTDS settings under my main DC to be retired. Highlight it on the left and there is nothing on the right hand pane. If you Right Click and bring up Properties, under the object tab is this: my.domain.com/Configuration/Sites/Site1/Servers/DC1/Exchange Settings

DC1 is where ADC was installed...does this folder have anything to do with it?

I demoted my old former PDC and it was still left in AD Sites & Services, but only with the Exchange folder underneath...no NTDS settings item. I just deleted the server.

Exchange "seems" to be working fine, but anytime a domain controller gets rebooted, my Exchange server will log an error saying the former PDC is not reachable:

Event Type: Error
Event Source: MSExchangeAL
Event Category: Service Control
Event ID: 8260
Date: 5/15/2005
Time: 12:53:28 AM
User: N/A
Computer: Exc-svr
Description:
Could not open LDAP session to directory 'oldpdc.mydomain.com' using local service credentials. Cannot access Address List configuration information. Make sure the server 'oldpdc.mydomain.com' is running.

Now, I have another site over a VPN and I manually had to remove a bunch of DNS entries referring to the old server in order to get my site links to update themselves to the new PDC. The only thing
referring to the old server is just the computer account in AD...a member server. This old PDC is completely off-line and Exchange and clients seem to work fine.

...and my first reboot of Exchange after that demotion, I got the following event info:

Event Type: Information
Event Source: MSExchangeDSAccess
Event Category: Topology
Event ID: 2081
Date: 5/15/2005
Time: 12:03:50 AM

Description:

newPDC.mydomain.com

The Configuration Domain Controller is set to DC2.mydomain.com.

So the topology was updated, but that error was still logged when DC2.mydomain.com was just rebooted
