I'm in the middle of a migration from an old virtualized Windows 2003 Terminal Server to a 2008 R2 RDS host. The environment is a mix of several generations of HP thin clients, as well as some Axel hardware terminals.
The first batch of users migrated well, but as we encountered people with older HP devices, we discovered that some simply could not connect to the Windows 2008 R2 server.
One device type is Linux-based. HP thinconnect... and RDP sessions initiated to the new terminal server disconnect immediately. That issue has been traced back to the Linux
The other device type, of which there are many in the environment, is the HP T5510 Thin Client. It runs Windows CE 4. New connections to the terminal server result in:
Because of a security error, the client could not connect to the terminal server
Connecting to the old Windows 2003 server works fine. So this is specific to the HP Thin Client interaction. Network Level Authentication (NLA) is disabled.
Any tips on resolving this?
Will new thin clients need to be purchased?
