  My Setup: I have a central database (MSSQL express 2008) and some clients (MSSQL 2008 express) .
  
  I build a simple console sample based on http://msdn.microsoft.com/en-us/library/dd918848.aspx
  
  I need to upload two tables (data only) from every client to the server. The two tables have identical structutre at all clients. Each table has a column named "clientid"; this id allows to identify the client sent the data.
  
  
  I am using filtering in clientid column to do the job and fifferent scope for every client but I have the followin problem:
  
  Server: provisiong ok
  First client: provisioning ok, data uploaded ok
  Second client: provisioning ok but the data not uploaded!
  
  TIA
  
  Sample code is shown below :
