I have a client that has 2 domains domain.com and domain.org and they have 2 locations with VPN access to see one of another. The reason for the separation is that one location is the corporate office(domain.org) and the other (domain.com) handles donations and such. they are non-for-profit. Corporate employees have offices in the 2nd location, and the networks were originally separated. The separate networks hindered productivity, and we have added everything to the same network. The corporate office has a secondary DC in location 2 just in case internet goes down, so now the 2nd location has the DC with Exchange for donation side, and the secondary DC for corporate. I disabled DNS and DHCP on the secondary DC since on the same network for the donation side. I pointed the secondary DC DNS to the DC in the corporate location. I am not really concerned about the internet going down...
I have to keep the separate domains but be able to see one another, the problem I have are the exchange portion. I can set static IP's on the desktops used on the corporate network and Outlook open successfully. If I have it pull DHCP from donation server, obviously it goes down. I have users that use laptops, and cannot have static IP's and they do not want to have to input one when they go to the 2nd location. I need Exchange to work even if it pulls from DHCP on the donation server (domain.com)
So I tried to create a trust between the domains and it is failing. I am not sure why, I can ping everything but cannot get the trust working. Would the trust help me to get everything to see one another. Do you think any easier solution can be put in place, any suggestions.
I know this is confusing, was a little difficult to type out. lol.. Thank you in advance for any help, I appreciate it.
