A customer uses thinclients with the 2x thinclient operating system.
Since we updated from a 2003 Server to 2008 Enterprise Server (not R2) the thinclients can no longer connect via RDP. Windows xp and windows 7 clients do connect fine.
The error massage on the thinclient is:
Your RDP session has been terminated. (TCSS005)
failed to extract public key from certificate
Connection reset by peer.
There is no log on the server which I can identify to match the event.
Searching the internet I found lots of posts which state the problem is related to an old rdesktop version.
I set up an test environment eaven from the same media as the productiv server. In the test environment the clients with the exact same client os version have no problmens to connect to the server.
The productive server is member of a win 2003 domain. The domainserver is the license server. The RDP-TCP connection is configured as follows (I hope I translated it correctly):
security level: negotiation
encryption level: client-compatible, also tried low
NLA: off
Can anybody help with this problem?
