Crystal report logon failed – We have client-server based on the Visual Basic program, this program is running on Windows 7 Professional and connected to the SQL server. The program is working fine, but when we did a clean install on other machines there is an error message “Logon Failed” on Cyrstal Report Viewer window when a user tried to print a report.
We have had check the security credential on SQL server, check the ODBC setting on the control panel, tried to add a user as local administrator on the client computer, etc. but was not working.
Later on, I found that there is a group on the SQL server called SQLServerMSSQLUser$ranap2$MSSQLSERVER (ranap2 is server name), by adding the domain user account to that local group it solved the problem.
