Good to see you back here and posting. Even if it is just cause you are stuck!
Been a while since I played that, but if you are where I think you are, there is a control of some kind on that generator that you can shoot or open ... I know it's vague.
Once you activate this, the 2 guards that are keeping you from getting through the door come to see what all the noise is and you can take them out.
I'm sure you will inform me in no uncertain terms if the advice I'm giving is for the wrong are, btw.
and just so you have something to yell at me about -->
