We have an environment where the Active Directory servers are Windows 2003. However, we have built some 2012 R2 Terminal servers that use those Windows 2003 servers to authenticate with. Unfortunately, when a user's password has expired, the 2012 R2 server comes up with a message that I have included in the attachment. We don't know what to do either. I know the AD controllers need to be upgraded, but is there no solution but an ugprade?
