After installing WhatsUp Gold on Microsoft Vista, the WhatsUp Gold Task Tray Application does not connect to the database if you log in to Windows using any account other than the account used to install the application. To correct this issue, execute this script from the command line in the C:\Program Files\Ipswitch\WhatsUp\DB Scripts\ folder:
sqlcmd -E -S (local)\WHATSUP -d WHATSUP -i grant_all_users_read_access.sql
Important: If you run the above script, all database users (admin and others) are granted read access to the WhatsUp Gold database.
