HI all I just go for my 70-330 exam based on security but I failed, got 610, I find it really tought by the way, I got a lot of question based on COM+ security and remoting.. How should I approach my retry? I use the MS press book.. I was using transender as testing but this test was too simple compared to what I get. Should I stay closer to the test of the MS press book ? One thing is hard also is to test Remote situation with COM+ served component from home as I have a single PC nothing else, so sometimes you need to admitt that its like this but I was not reaaly able to reproduce th situation in real and Labs in MSpress are all based on a single machine. HOw to approch my next retry ? thnaks for your help regards Serge
