Uninstalling Exchange 2003 without Add/Remove Programs listing

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.

Try setup from the install source and see if the 'Remove' option is available

Otherwise try
setup/?

And see if there is /u for uninstall...

Or maybe just try install the management tools and see if that allows you to remove everything when you run setup again

What's still there? The services or the files or both?

The only things related the Exchange left in Add/Remove Programs are these  two listings:
- Microsoft Exchange Server Best Practices Analyzer Tool
- Microsoft Exchange Server Performance Troubleshooting Analyzer

"Microsoft Exchange" is no longer there, but Exchange is still installed on the server.  I can open the Exchange System Manager.  The Exchange services are still listed in Services.  The program folders are all still there.

It appears that it finally accepted the Cancel command, but removed the Add/Remove Programs listing.

If there's an uninstall executable somewhere in the application folders, I'll run that, but it's a deep and complicated structure and I would only be guessing at what the filename would be.  Does anyone know?

Thanks,

I tried installing the management tools from the installation disk and I got to the screen that would allow me to remove Exchange.  When I continued with that it got to this error:
Setup failed while installing sub-component Exchange ActiveSync with error code 0x80072030...

It then gave me the option of canceling or retying.  Retrying didn't do anything but bring back the same error.  Canceling gave me this error:
Setup failed while installing sub-component Microsoft Exchange OMA Browse with error code 0x80072030...

Canceling this one continues with removing other files.

It completed with this message pertaining to the failed step "Microsoft Exchange Messaging and Collaboration Services":
There is no such object on the server.
Facility: LDAP Provider
ID no: 80072030
Microsoft Exchange Setup

After the reboot, the server came back up and Exchange appears to be gone with 1 exception.  These services are still listed in Services:
- Microsoft Exchange Information Store
- Microsoft Exchange Management
- Microsoft Exchange MTA Stacks
- Microsoft Exchange System Attendant

Any idea how I can get rid of these services?

Srvinstw.exe should be able to remove them

Thanks for the points, did srvinstw.exe manage to remove those services for you?

I haven't gone there yet.  I'll check it out at some point, but that's a much lower priority right now.

I couldn't find srvinstw.exe, but I was able to remove them with instsrv.exe with no problem.

Thanks for all your help!
