The Exchange 2007 readines check yieled Active Directory Connector must be decommisioned 1st.
I have looked and cannot find it in services or add/remove programs on any of my machines (mail server or DC's). I did find a log on mail server C: showing the install of it on my mail server. The date inside the log matches the date on the the ADC object listing in AD Sites and Services on my DC. I cannot find a service running on that machine and it is not in add/remove programs. I tried running adc setup on the mail server from the Exchange 2003 cd. Setup wants to install it, not give option to uninstall. I don't think it's there anymore.
So can I just delete the ADC item out of Sites and Services?
It could be an installation from an Exchange 2000 CD.
There could also be elements in adsiedit.msc.
Does the log make any reference to a server you no longer have?
Instinct says yes, remove the item, but I am just wary of other bits left behind.
