slove this problem.

I have no idea myself, but under "Nonpartitioned, Bidirectional,
Transactional Replication", Books Online says that to implement
bidirectional transactional replication "substantial customization and
programming is usually required."

So you might get a better response in
microsoft.public.sqlserver.replication, as it seems to be something
quite specialized.
