You are right. The trial I'm doing is using a single PC with everything on (SQL server 2000, web application and lansweeperservice) The problem was, probably, that the database was involved with lansweeperservice and it has no time to "answer" to the web call. Now all is work properly. Thanks,
Actually sometimes I'm able to open the web consolle but I can't see any data coming from the database. The system have scanned more than 4.000 PC. You can see my desktop.
