Hi amele1, in the EPO450-CommonSetup.Log file you can see this:
20100324115120 Testing NT Authentication to SQL Server.
20100324115120 Failed to connect to SQL Server [PCVR-WSUS-01\EPOSERVER] with error code [0x80004005]
20100324115120 Description for error code is [Cannot open database "ePO_PCVR-WSUS-01" requested by the login. The login failed.]
20100324115120 Failed in connectToSQLServer with error code .
So either your user does not have permissions on this SQL server or perhaps you don't have TCP/IP Enabled on the database.
If you open the SQL Configuration Manager console you will see if TCP/IP is enabled (same as Named Pipes and Shared Memory)
Hope it helps
