After Power failure, OWA and ECP are no longer working - Exchange 2013
Posted on 2014-01-11
We experienced a power failure today and unfortunately, the UPS didn't last long enough. The server was in the process of shutting down when the UPS shut down. After the power was restored, the server appeared to come up properly. However, I am no longer able to access OWA or ECP via browser.
Initially, when I would attempt to login (as Administrator), I was just returned to the login page. However, after doing some research, I changed the Authentication mode from "Basic Authentication" to "Windows Authentication" in IIS for both the owa and ecp virtual. Now, I am getting "The user name or password you entered isn't correct. Try entering it again."
I get this login error regardless of which username/password I use. Please help.
