Running Baseline Configuration Analyzer, I get the "One or more Servers containers in your Exchange organization are empty - Source 325". I am following instructions at https://support.microsoft.com/en-us/kb/2487271
to address this issue, however there is no CN=Services container as described in the article. I have thoroughly checked adsiedit.msc. The only area where I have the CN=Servers container is in the CN=Systems container. And that is not empty. Not sure where else to look to address this issue. We had upgraded in the past from SBS 2003.
