If the following error is received when trying to setup and connect to Eralis Services Manager, then the issues lies with the SQLconnection for that logged on Windows user.
Login to SAP Failed: Failed to connect to SBOCommon
The connection that is trying to be established, is using windows authentication and the user that the system was trying to connect as does not have authorization to access the SQL server.
The resolution is to login to SQL Management Studio as sa and add the windows user as a login (give the user sysadmin rights) which then allows the Services Manager to connect.
I would start by trying a validation and then check the windows application event log to see if there was an unsuccessful login to SQL which will also give the username the system was trying to login as.
