I was in the process of uninstalling Exchange 2003 and I came across a problem...
We are now completely on Exchange 2010. All of the Exchange services on the E2003 server have been disabled for a couple of weeks now. I did that to see if there were any errors or problems; there have been no problems. This tells me that nothing is pointing to the old Exchange server.
I went to the Control Panel > Add/Remove Programs and started the uninstallation of Exchange 2003. I didn't realize that part of the process was to stop the IISADMIN service. This is a problem during the day as we have other sites that are being served by this server. It hung up on this step for a long time. I hit Cancel and it told me that it couldn't cancel until this step was completed. I checked a while later and it told me that the uninstallation was completed and a reboot was necessary.
I rebooted the server and checked for Exchange; it's still there. What's strange though is that the listing for Microsoft Exchange is no longer in Add/Remove Programs.
How can I restart the uninstall wizard without the listing in Add/Remove Programs?
Thanks for any assistance.
