During my setup progress I want to run a sql script, but unfortunately setup is unable to connect to my database. From a prestarting setup.exe I set the property IS_SQLSERVER_SERVER and skip the SQLLogin-Dialog. So the IS_SQLSERVER_AUTHENTICATION-property should be by default 0, that's what the property manager says (this means windows authentication). I get the error message, that the user (null) is not part of a trusted sqlserver-connection (ADO Error: -2147467259.
If I try the same thing in M$ SQL Server Management Studio I can connect without any problem to the server...
P.S. I get this error only for sql servers running in LAN, local sql servers work fine. P.P.S. Same problem if I don't skip SQLLogin-dialog...
