Cannot remove ADC after removing 5.5 Exchange Servers

All migration was completed and 5.5 servers removed as per the MS articles.
I cannot uninstall ADC. I get a message saying there are active connectors
that have to be moved. The managment console seems of no help, and I have
been unable to locate any articles that shed light on this. The message
terminates the uninstall.

Any suggestions? Thanks in advance.
