This is what I have done and what is not working:
On the server I went to each appropriate user and added their machine as a "Local Administrator"
On their local machine when going to the Administrators Group I am not able to add domain_name\User_name
On the location tab the domain is not showing up!
Okay so I believe my problem is related to the DNS information I added to my server so that we would have remote access through a vpn to the server. Our ISP (Cbeyond yuck) gave me the Adapter setting to use so that we could use their VPN portal to access multiple machines remotely throughout the domain. We do not have direct access to their managed router so I had no choice but to follow their steps.
I need help with this, hopefully tonight since I will be here late trying to get this worked our before everyone returns in the morning.
Thanks so much!
