Unable to remove exchange 2003

I have completed a migration (coexistence) from exchange 2003 to 2010.  I finally decided to uninstall exchange 2003 so I went through add remove programs and selected the option of "remove" and received an error message.  Unfortunately I didn't record the exact error (bad move on my part).  Exchange 2003 doesn't appear within add/remove programs but it seems as if its still partially installed.  It is still apart of AD on this server and system manager is still installed.  So i have done some digging and tried a few different options one of which is to remove the server from first administrative group within system manager, when i try to I get an error

"the system cannot find the file specified"
facility: Win 32
ID no: c0070002
Exchange System Manager

There are so many different articles to sift through so I'm hoping someone can steer me in the right direction.

What you can try is moving the installation files to your Exchange 2003 server and then from there launching the setup.exe. This should then detect the install (if it still exists) and you should be able to continue the uninstall. If you are still unsuccessful, you might have no choice but to remove Exchange using ADSIEdit.msc.

I have had this happen quite a few times. What I usually do is reinstall Exchange 2003 using setup.exe from the installation media - you will get prompts because of the mixed versions. Then attempt to remove it again. Very rarely do I have to adsiedit hack the machine out.

ok so i re-installed exchange 2003 and then removed it again.  I think that its fully removed although all of the old .EDB and STM files are still there.  Is it safe to manually remove these old database files as they are significantly large?  Is there any other way to determine if exchange 2003 has been completely removed?

Thanks

The uninstall process doesn't remove the databases.
Quickest way to verify if Exchange has gone completely is to look in Services and see if any Exchange related services are still there.

Get-ExchangeServer on the Exchange 2010 server shouldn't list it either.

Is it ok to permanently delete the old exchange database files now that it uninstalled?

You shouldn't see any reference to Exchange 2003 in Get-ExchangeServer.
Have you rebooted the Exchange 2010 server since removing the 2003 server?

Removing the database files isn't an issue, those are now useless to you.
