Hello everyone I would appreciate any help or direction on this. I am getting even id 4004 errors on my domain and exchange information store won't mount. Looking around I have found a site saying that this happens if you have two domain controllers and wrong dns settings. My settings at the moment are DC1 First dns pointing to itself Second dns pointing to DC2 DC2 First dns pointing to itself Second dns pointing to DC1 According to that link, I have to change it in a way that they first look at each other then them selves. Is this correct? Imean in that case, then DC1 First dns pointing to DC2 Second dns pointing to itself DC2 First dns pointing to DC1 Second dns pointing to itself Thank you for response
