We have a small 2008 R2 Active Directory environment with 2 domain controllers and 13 member servers. We have no additional features such as an RDP gateway or Federation Services - just a plain AD setup. We now have a requirement from our client to have a two factor authentication solution for each time we logon to any server, either using RDP or locally. We only have 4 admins that ever logon to these servers - we do not have any "regular" users.
Is there anything out there that would work in this environment without having to modify our AD (at least nothing major)?
Thanks
