Hello Dragan,
thank you for the quick reply. Yes all three users have the performance problem. We all connect through the SQL connection method to the server.
I've allready checked the SQL Server. The Server has nothing to do. I made a trace and the only querries are about ontime (three users) and reporting services (for the same three people, reporting from ontime db). Statistics, Indezis are up to date.
regards
Andreas
