If you have multiple versions of server (e.g. 2003, 2008) you may have compatibility issues with the licensing.

Because you say only the Administrator can access, I'm assuming you have programmed the exception in the firewall and/or windows firewall

The next step would to be to run WireShark https://www.wireshark.org/ on the workstation and compare the authentication traffic for Administrator to another user's logon. Although this might not be productive.

From your description, I keep coming back to thinking that it is a policy.  If the administrator's credentials work and  another user's don't on the same machine, it seems to point to Windows security and not the firewall.  Perhaps the licensing on the RDP server.  Have you checked to validate the application of licenses on the Terminal Server?  The only difference between a user and an administrator logon is groups and policies.  It sure seems like it needs to be there.
