The main challenge I _think_ you will have is that the install will try to create a routing group connector and (depending on how much of the 2000 server is left in AD) use the SMTP virtual server on the Exchange 2000 server to send email.
You can defeat that by, after completing the install, removing any RGCs that are present, and creating an Internet Send Connector on the new server. Obviously - IMO - you should still get that server taken care of. You won't be able to upgrade to Exchange 2010 or later while it is still in AD. Regards, Michael B.

My next task on this network is to install a new E2007 server. (We already have E2007 installed and we're migrating to better hardware). I'm installing E2007SP3 on Win 2008R2 and I'm under some heat to get the new install up and running. The install reports under Mailbox Role Prerequisites that it can't find an RUS for each of our three domains. That makes sense because I removed the RUS as part of removing the last E2000 server. Since E2007 doesn't use RUS, I'm guessing that that this error is due to the remaining E2000 server that I haven't managed to get rid of yet. Does anyone see any problems in going ahead with the E20007 install?

In regedit, there's no "properties" selection displayed. In regedt32, I can get to permissions from the security menu. There a lot of groups with Full Control.

Is there a way to pin down the culprit? In REGEDIT, "registry keys" are displayed as folders. So key==folder. The things that appear in the right pane are "registry values". What are the permissions on the key in question? That is: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application\ You can find out by right-clicking the folder icon for the key in question, and choosing "Permissions". Chances are, the permissions on that key don't grant everything needed to the user account you're using to run the Exchange uninstaller. -- Ben
