We recently added a new domain controler, as well as a new dedicated terminal server, to a network. &nbsp;After moving over DNS, DHCP, FSMO roles, files and shares, we shut down the old DC before running DC promo on it as a test. &nbsp;Everything was fine for a couple of hours, but then they started having problems. &nbsp;Outlook would not connect, instead, it gave users the message &quot;outlook is requesting data from the server&quot;. &nbsp;Users could not log in to the terminal server. &nbsp;When we turned it back on, everything came back up. &nbsp;Any ideas on what we should look at?
