allow external computers to access the DC or domain users
this is my first post. I'm sorry if i posted in the wrong area.
I want to allow an external server to be able to use Domain Users or Authenticate the users with Active Directory. I don't want to have to use VPN. How can that be done?
Currently we have a couple applications installed on the external server that uses active directory. The way it works now is that, that external server needs to VPN to the network all the time so that the active directory users can be authenticated.
How can I make it work or which technology needs to be used so that it will still authenticate ? ADFS? create a trust between the external server and the internal DC? how?
Both of the servers are 2008 R2.
