The problem is that I don't have any clue on how to solve this. I've 
googled around and there seems to be similar cases, but no explanation 
solution, maybe there are some restrictions when loading a dll?. Just to 
have a bit more infomration, which Win32 OS are you using, XP, Vista, 7?

And we can't even put a decent timeout since according to

http://msdn.microsoft.com/en-us/library/aa391769%28VS.85%29.aspx

the alternative is to have a timeout of *2 minutes*. I really don't know 
why thi is happening, but I don't think this has an easy fix. BTW this 
function was necessary to obtain a bootup time that does not change with 
hibernation or clock adjusments, previous bootup timestamp function was 
a huge source of problems for Interprocess users.

Best,
