Corrupted distribution.mdf

We have started getting the following in the application event log:
Error: 823, Severity: 24, State: 2
I/O error (torn page) detected during read at offset 0x00000015ba000 in file
'd:\sqldata\MSSQL\Data\distribution.MDF'.
and is being generated during distribution cleanup.
We have NO backup of the distribution database.
How can I repair the database?
In hopes to recreate replication, I've tried to disable publishing and
distribution, but I get the following error:
SQL Server Enterprice manager could not disable the distribution on xxxxx
Error 823: I/O error (torn page) detected during read at offset
0x0000001115ba00 in file .../distribution.MDF
Also ran DBCC CHECKDB and get:
... CHECKDB found 0 allocation errors and 2 consistency errors in database
'distribution'.
repair_allow_data_loss is the minimum repair level for the errors found by
DBCC CHECKDB (distribution ) ...
It's seems I can't run the repair_allow_data_loss on the the distribution
database even if in single user mode. (tried starting in single user mode,
but can't get in query analyzer to run the repair - is there another way?)
Any Ideas on repairing/rebuilding the database would be appreciated.
resolved myself by:
- generate creation script to recreate current replication configuration
- manually deleting distribution database
- disable publishing and distribution
- run creation script
