A couple weeks ago, my main ad computer failed. I (with experts help) got it running again. I wanted to make sure my other server was a GC and did so by checking the proper box. WHen I checked later to make sure it worked, this is what I got.
I am getting errors when I tried to make a second server in my domain a GC. I attached a copy of the dcdiag. I am not sure what to do to fix this. My DNS seems to be fine.
I know you will require more information, so just ask.
