Hi,I am unable to login CWA .Error: A problem occurred and the session was ended. Please sign in again. If the problem persists, contact your system administrator.(Error code: 0-0-18401-0-0) RegardsDeepak Srivastava

Hi,Most probably it is going to be a certificate issue. Make sure your SSL certificate is assigned to both the IIS site hosting CWA as well as in the CWA admin console. Check your configuration as per the below link: http://technet.microsoft.com/en-us/library/dd425345(office.13).aspx Regards from www.windowsadmin.info
