Active Directory user account connecting to Windows Server 2008 R2 terminal server

Hello,
We have 44 RL90W Wyse clients deployed at a school connecting to a terminal server. Each student has an active directory account to connect to this terminal server. At the beginning of school this year, the AD accounts were setup to change password at first login, but they were unable to change the password through the Wyse Client. After entering the temp password, it comes up saying change password, click ok and then kicks them back to the RDP window to connect again. We have used the same user accounts from a Windows 7 machine to remote desktop and it works fine, but from a a Wyse client, its not working. We can set the user account to not require a password change and it lets them in fine.

Any ideas?

Thank You,
Jason
