I have a single W2K3 domain server. I had an issue with my modem and had it swapped by a tech and he gave me new dns entries. I made what I thought were the right modifications... now I keep getting the 5781 error and cant figure out why. I called the ISP and they switched me back to my original dns entries. I know that both forward and reverse zone are both running. I have also ran nltest /dsregdns and it returned no flags. I cant figure out what needs to be changed.... any help would be greatly appreciated!
