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?
That is the remnant of the ADC. Assuming you have flipped over into Exchange Native mode (or really even as long as you don't have any 5.5 servers any more) then you don't need to worry about this at all. Just go thru the process of decommissioning the Domain controller liked you plan there should be no problems due to this object.

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.

Oh, 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 User: N/A Computer: Exc-svr Description: Process MAD.EXE (PID=1712). DSAccess will use the servers from the following list: Domain Controllers: DC2.mydomain.com newPDC.mydomain.com
Global Catalogs: DC2.mydomain.com newPDC.mydomain.com
The Configuration Domain Controller is set to DC2.mydomain.com.
You are probably getting this error because your Recipient Update Service is pointed to the old domain controller. Simply go into the ESM can point the RUS at a current valid domain controller and this issue should go away.

I do have 2 Recipient Update Services...one called Enterprise Configuration and the other called the same as my Organization name. This was a migration from Exchange 5.5
Which one is safe to delete? I've pointed both of them to my new PDC and they're both set to Always run.
You need both of them they server different purposes. The Enterprise RUS is responsible for system objects and the domain RUS is responsible for users.
