Server 2000, and all client computers run Windows XP rofessional and Windows Vista. named COMPANY-DB111, which you administer at a regular interval of time. COMPANY-DB111 contains and hosts three databases that support different types of business requirements. The network uses the DBA database that supports internal operations including maintaining data, accounting, and mailing. The network's regular users make use of stored procedures for the data values that need insertion into the tables. The stored procedures used in the network of the company are designed to access SQL variant type parameters and then use the values to build and execute ad hoc query statements that are the part of the SQL statements. During a routine network check, you discover that there are several odd occurrences in the database. The odd occurrences include data deleted from tables and other unauthorized activity. You suspect a user is executing the unauthorized statements through the stored procedures. You are required to stop the unauthorized changes while having least impact on the stored procedures that are in use. Your explanation must use the least administrative effort. What should you do?
