Curruption of Database

Dear Sir,

I am using Access 2000 with VB6, ADO 2.5 & Microsoft.Jet.OLEDB.4.0 in my 
application.

In my application all Inserting / Deleting & Updating process is within 
BeginTransaction &  Commit Transaction.

All tables of database is having primary key & required other indexes.

All tables of database is related  with parent table and enforce
referential 
integrity.

I am using INSERT, UPDATE, DELETE Query to manipulate data.

I am not binding recordset with any control.

Then also in multi-user environment my data gets corrupted in some of
Local 
Area Network when any of machine is having problem or hangs while saving.

Can any one explain me why this ?

Thanks in advance for sup****t.
