Rows in the sysdepends system table that relate to intra-table dependencies (for example, computed columns or check constraints) may be removed inappropriately under the following conditions:
You may also find that SQL Server generates an Assertion in the SQL Server error log.

Drop, and then re-create the computed columns or check constraints on the affected table to re-create the entries in the sysdepends system table.
Microsoft has confirmed that this is a problem in SQL Server 2000. This problem was first corrected in SQL Server 2000 Service Pack 1.
When you create Full-text index on image columns, SQL server adds one more row to the sysdepends system table for the image column dependency. When you remove a Full-text index, SQL Server deletes that row from the sysdepends system table. However, SQL Server might accidentally delete other rows that keep intra-table dependencies. No errors are reported when the rows are removed from the sysdepends system table inappropriately.
