Active Administrator requires the default collation for the audit database. In SQL Server, collation refers to a set of rules that determine how data is sorted and compared. Active Administrator supports only the default collation and sort order configurations for the audit database.
If you are unsure of the collation assigned to the audit database, use the Microsoft ISQL_w or Query Analyzer tools, connect to the database, enter sp_helpsort, and run the statement. The results list all sort and collation information for the database.
