EVDashboard is a browser based solution to help manage your Symantec Enterprise Vault environment. Backend scripts collect data outside of business operating hours, the web gui then uses this data to provide MI reports and system health information.
From drawling re 2008 r2 installation:
Just a quick note to help out anyone else trying to get EVDashboard to work with R2. I had to allow "NT AUTHORITY\ANONYMOUS LOGON" db_owner rights on the EVDashboard database (and obviously create a login for that NT account) for it to work. Without this anonymous account, even the Test DB Connectivity page would error out.
