Unable To Drop Index (6.5)

Hi,

I have a table which I am unable to drop the index.
I tried to drop it via the TSQL and GUI interface (Indexes dialog box),
but when I clicked on table refresh, the index still there.

Below is the result after DBCC commands:

1. DBCC checktable(TB_LOCLoan)

Checking TB_LOCLoan
The total number of data pages in this table is 146542.
Table has 1596232 data rows.
Msg 605, Level 21, State 1
Attempt to fetch logical page 462136 in database 'DM_LOCLoan' belongs to object '1744009244',
not to object 'TB_LOCLoan'.

2. DBCC newalloc(DM_LOCLoan)

TABLE: TB_LOCLoan OBJID = 832005995
INDID=0 FIRST=60168 ROOT=642778 DPAGES=146542 SORT=0
Data level: 0. 146542 Data Pages in 18393 extents.
INDID=5 FIRST=463752 ROOT=463739 DPAGES=5304 SORT=1
Msg 2525, Level 16, State 1
Table Corrupt: Object id wrong; tables: alloc page 463616 extent id=463752 l page#=463752
objid in ext=-832005995 (name = -832005995) objid in page=832005995 (name = TB_LOCLoan)
objid in sysindexes=832005995 (name = TB_LOCLoan)
TOTAL # of extents = 18393

3. From Error Msg 2525, I have tried the suggested action

use DM_LOCLoan
go
select indid, name, object_name(id)
from sysindexes
where id=832005995
and distribution=463752
go

This query does not return any row.

I am running out of clue of how to proceed! Anybody come across this problem before?
I am very eager to solve this problem as the table is hanging here, I can't even drop it to recreate
and continue data loading.

Thank you.

Regards,
Joo Pheng
