I'm trying to remove the Active Directory Connector from an Exchange 2000 server in a Native Mode environment. It's telling me that setup was unable to find the installation files. When I go and browse to the location of the ADC.exe file, it tells me that the version of the installation program is older than the one previously used. See the screen shot below ADC-uninstall-error.doc
In troubleshooting so far, I went into ADSIEdit and removed the entry from Active Directory Connections under Services in the Configuration container.
