This is a valid question. Surely there are those among you with the experience and expertise to provide guidance on this issue.
Better an inexperienced , yet cautious approach, than pressing the button just to see what happens.
I have the domain administrator password for the domain at my work location. I do not have the Domain Admin password for the domain at our other location. They are reluctant to divulge it unless absolutely necessary. (I do have a Domain Admin rights account on the second domain)
The main reason for the reluctance seems to be tied to the fact they (the senior administrators) are just as reluctant to consider changing the Domain Administrator password.
These domains were started on NT server by administrators who have long retired.
Maybe an intelligent discourse would provide some guidance on what NOT to do along the way, in relation to the Domain Administrator and the issues it may affect down the road
