Table Corrupt: Object ID 2, Index ID 0. Keys out of order on page (1:2432),

DBCC results for 'blc'.
CHECKDB found 18 allocation errors and 0 consistency errors not associated
with any single object.
There are 758 rows in 39 pages for object 'sysindexes'.
CHECKDB found 0 allocation errors and 1 consistency errors in table
'sysindexes' (object ID 2).
CHECKDB found 18 allocation errors and 1 consistency errors in database
'blc'.
repair_allow_data_loss is the minimum repair level for the errors found by
DBCC CHECKDB (blc ).
DBCC execution completed. If DBCC printed error messages, contact your
system administrator.
First, with everyone off the database, run DBCC checkdb again to ensure it
was not a transient error caused by multiple users making changes during the
original run...
If the errors go away - no problem.
If the errors are reported again, prepare to restore from backup... Open a
Call to Microsoft PSS as well, they may be able to help you...
