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.
It seems to me only the Thin Client connecting to this Windows 2008 R2 RDS has this issue. I think it could be the security issue, but can’t figure it out.
SOLUTION:
Finally, I fix the problem. The problem is the Thin Client try to access the RD Server using SSL but doesn't have correct certificate. To fix it, go to RD Manager, change the security layer to RDP Security Layer from Negotiate under General tab.
