Something happened to a pc where SQL 2000 & GP is installed locally.
When trying to see the smartlist, the windows is empty. Also when clicking the lookup no contents appear.
However, if we click on the navigator button at button left of of a inquiry window, we get a SQL Error (see pic). If we click on lookup a master record, it works; it gives the error when inquirying a inquiry window that would display transaction.
After reading the error, it looks that it may be the SQL instance
