Hey , I installed a GT forum in Win2k Advance server(+SQL server+Active Perl) environment, When I want to add a new forum, always getting a Error tips like this:

Failed to execute query: 'INSERT INTO gforum_Forum (forum_last,forum_allow_guest_attachments,forum_allow_user_edit,forum_allow_attachments,forum_name,forum_total,forum_attachments,forum_style,forum_total_threads,forum_new_timeout,forum_last_poster,forum_move_pointer,forum_sort_rank,forum_last_id,cat_id_fk,forum_edit_timeout,forum_desc,forum_hard_delete) VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)' Reason: [Microsoft][ODBC SQL Server Driver] (SQL-22018)(DBD: st_execute/SQLExecute err=-1)

Who knows how to resolve this problem? Thx a lot!

ps:And more about Security ( GT Forum in the win2k ), how to do that? Like forum admin director etc.
