Question

I am running into a wall with the whole p/invoke issue. I need to do this programmatically in C#.

Answer 1

I did the p/invoke stuff (with the LSA wrapper) a couple of weeks ago. I got an exception the first time I run the wrapper, but it succeeded the second time on Win2k8 server 64 bit.

Something like this worked for me

try{
   DoThePInvokeMagic();
}
catch(Exception){
    // Sometimes the first invocation fails, but the second time it seems to work       
    DoThePInvokeMagic();
}

Unfortunately we did not have time/prio to investigate further why this happened and why it worked the second time, since we got it working on all our servers.
