I have finished Wincc redundancy project on master computer and transfer it to "stand by" computer with Project Duplicator.The redundancy is working OK, until I restart the"stand by" computer. The problem is that when I try to open the project on restarted "stand by" computerI get warning "database context does not exist or is invalid". Where is the problem, what should I do? (I try todelete the project and duplicate it again,- the same problem occure)

BC normally at stating period the both computer will sychonize all database and possibly in your case there is conflict during copying data base. Hopefully it gonna be working. Yai
