We recently rolled out towers to all of our remote offices, and added a domain controller to each site. but when I plug in the towers then I have to give it a static IP so it can communicate with the DC. If you leave at the obtain automatically then it will not communicate with the DC which will not allow the user to login. Out of 7 sites 2 of them work just fine if I plug in the PC it gets an IP address and it works fine, but a previous person set those up. I did the other 5 sites. I can use the static IP, but if something happens I have to remove the tower from the domain an re add it to the domain it will not let me re add unless I was at one of the other 2 sites.
What am I forgetting?
Thank you in advance!
