Thanks, I just got frustrated. Sometimes they change things that work great and then they screw it up (generally speaking). I was having an issue where I needed to move the Server off the Data Drive - both on H drive and I couldn’t find the setting in the webpage/settings. Now they are separated. Server on C (SSD) and Data on H (a 500 GB, 7200rpm). Thanks for your help.
