I have spent the last 4 hours looking for solution online including Microsoft sites. So unless you have an EXACT match of solution to problem DO NOT tell me to TRY this or that in any article as I have probably already read it or tried it.
OK onto the issue.
Brand new 2008 R2 SP1 standard Dell server. All updates applied. Joined as a stand alone server to domain. Remote desktop role installed. License server role installed. License server activated. 10 Per User RD (open License) Cals installed. Remote Desk Host Diagnostics gives clean bill of health. No other roles etc. installed. This is strictly a TS server.
Workstations are Wyse thin clients running Windows 7 Embedded. They can see all allowed resources on domain. they can get to the internet as well. network connectivity and navigation confirmed.
So.... When I start up RDP client on said terminals I get error of: The remote computer disconnected the session becase of an error in the licensing protocol.
Remeber this is a Windows 7 embedded. hacks to registry or file copy from other OSes do not apply.
And yes I checked with Wyse support.
other Misc data:
No firewall activated on server
using the administrator account to attempt logon as it is already included in group. (Should not matter as it is a LICENSING PROTOCOL error anyway)
It is part of a 2003 domain.
No I have not edited GP on 2003 system.
Yes the event log has been reviewed. I see NO entries for this issue.
IDEAS?????
