HP Thin Client can't access Windows Server 2008 R2

We bought some HP Thin Client t410. I setup the Thin Client and connect to one of our Windows server 2008 R2 RDS. It worked for a week. I am back to the office after the new year, it can’t connect to the same RDS. Here are details.

1. If I try to connect the  Windows 2008 R2 RDS (no matter using IP, FQDN), I get this message: “RDP client error: Reboot necessary. The firmware has experienced a critical error”.
2. The HP tech support recommends me to download the new image Z5A42019 to replace Z5A41204. But that doesn’t fix the problem.
3. If I use the Thin Client to access other Terminal Servers, it works fine.
4. I also try another Thin Client, but get the same error.
5. All our XP and Windows 7 access the same Windows 2008 R2 RDS don’t have this issue.
6. The RDS Event Viewer doesn’t have any related errors.
